The program is structured by course, unit, and lesson. Each unit includes formative checkpoints throughout and an end-of-unit assessment. Lessons are approximately 45–50 minutes long. They are intentionally designed to fit within the calendar year, so teachers have pacing flexibility. Here is a breakdown by course of the number of units and lessons.

* Scopes and sequences are intentionally designed for Florida’s accelerated and honors courses.
**The time estimates in these materials refer to instructional time. Some lessons contain optional activities that provide additional practice for teachers to use at their discretion. Additional Centers and Activities are also available to differentiate instruction.

Math Nation Florida is built exclusively for Florida’s B.E.S.T. Standards, providing teachers with a highquality, standards-aligned curriculum that ensures all students can succeed in mathematics.
The design emphasizes:
• Student-centered, inquiry-based learning that builds from what students know.
• Scaffolded instruction within and across lessons, ensuring accessibility for all learners.
• Balanced development: conceptual understanding, procedural fluency, and realworld application.
• Multiple representations to deepen understanding and connect math to authentic contexts.
• Collaboration: students learn together and view mistakes as learning opportunities.
• Transfer learning: spiraling and connecting content across courses to highlight the beauty and interconnectedness of mathematics.
• Mathematical Thinking & Reasoning Standards (MTRs): embedded throughout for deeper engagement.
• Communication skills: consistent opportunities for oral and written mathematical reasoning.
Instruction draws on John Hattie’s Visible Learning research and incorporates:
• Practices with the highest impact on student growth.
• Classroom discourse and rich discussion opportunities.
• Clear strategies and content knowledge support in the Teacher Edition.
Teachers also have access to:
• Progress monitoring tools within a MultiTiered System of Support (MTSS): embedded assessments, reports, and analytics aligned to Florida’s B.E.S.T. Standards.
• Differentiation supports: remediation, intervention, and enrichment at both unit and lesson levels.
• Professional learning: point-of-use digital resources and a teacher community for continuous support.
Math Nation Florida’s Unit and Lesson Guides serve as a companion to our dynamic curriculum. The Unit and Lesson Guides accompany the curriculum for Grades 6–12, acting as an extension and planning partner for further clarification of the purpose, intent, coherence, and language of the lessons.
Each unit includes a Unit Guide that offers additional planning support for the unit as a whole. Florida’s B.E.S.T. Standards are designed to ensure vertical alignment across grade levels and horizontal alignment within each course. In the Unit Guide, the Unit Narrative section describes the content of the unit, including horizontal connections to other units. The Vertical Alignment section of the Unit Guide provides the vertical alignment for the benchmarks taught in the unit.
Each Unit Guide also incorporates instructional strategies for differentiating, enriching, and implementing lessons throughout the unit.
The narrative captures the story of the unit, its progression, and connections to other units and courses. This section also includes a Unit-ata-Glance that gives an overview of the lessons included in the unit.

The differentiation section includes recommendations for incorporating Universal Design for Learning (UDL)™ and information for English Language Learners (ELLs). UDL from CAST© 2008 prioritizes strategies for differentiating instruction that seek to eliminate barriers of entry so that all students can learn. Each Unit Guide offers techniques specific to that unit content through the lens of UDL.
This section offers visual coherence with benchmarks aligned to lessons and clarifications to inform planning and instruction.
This section provides the vertical alignment of the benchmarks taught in the unit by noting the benchmarks from prior courses that are being built upon, and the benchmarks in future courses that students are working toward.
Every lesson includes a Lesson Guide that provides insight into the math thinking and reasoning for effective implementation.
Each Lesson Guide begins with an introduction that captures a snapshot of the lesson content for purposeful preparation. The Lesson Introduction includes the benchmarks and learning targets found in each student lesson. Teacher planning supports include vertical benchmark coherence, essential questions, a brief lesson narrative, a component summary for pacing and adaptation, and resources, including materials and vocabulary.
Each Lesson Guide includes additional planning support, such as:
• Mathematical Thinking and Reasoning (MTR) Standards: one is highlighted for each lesson for intentional focus when planning, though a lesson may integrate several MTRs.
• Common Misconceptions
• Things to Consider
• Literacy and Language Routines
• Differentiation Suggestions: found here and also incorporated throughout the lesson components.
In the Lesson Guide, specific guidance incorporating instructional strategies is provided for each component of a lesson. This support is shown in line with the answer key of the student lesson for point-of-use implementation in the classroom. These recommendations include teacher moves, additional questions to consider asking, differentiation ideas related to the component, and possible enrichment ideas.
Student lessons across all courses feature the same structure. The lessons include several components, each with a specific icon associated with it.


Focus benchmarks are indicated on the first page of each student lesson.
Learning Target(s)
Learning Targets are clearly defined at the beginning of each lesson so student and families have clear expectations.

Every lesson begins with a Warm-Up. The Warm-Ups are designed to vary so that all students have access and a positive start to each lesson. WarmUps include bell work, STEM career profiles, critical thinking, and more.

Every lesson ends with a short Wrap-Up. Wrap-Ups include student reflection, cool downs, error analysis, and tickets out the door that can be used for formative assessment.
Lessons also include some combination of the components indicated below. Green lesson components identify student-led components that are intentionally designed for students to explore, discover, and practice concepts either independently or collaboratively with peers. These activities promote active engagement and deepen understanding of the content.

Explorations are student-led discovery, often involving student collaboration and discussion. The topics explored in these components may not yet be formalized.

Activities include gallery walks, data collection, and games.


Students collaborate in pairs or small groups.
Students may not have reached mastery when completing Try It. These problems are an opportunity to apply previously learned skills to more formal practice problems.
Blue lesson components indicate that lesson components are intended to be teacher-led. These provide opportunities for direct instruction and teacher facilitation of learning and are intended to be rich in student collaboration.

Instruction should be studentcentered during Guided Instruction, but may require more support from the teacher.

Guided Practice presents an opportunity for students to learn new concepts through practice problems.

Bring it Together components formalize concepts explored in the lesson.

Vocabulary and concepts learned in previous units or courses are reviewed in Refresher components.

Your Turn! provides students with the opportunity for independent practice. These problems may also be used for homework.

Lesson Activities serve as the core learning experience in every Math Nation Florida lesson. These engaging tasks:
• Encourage collaborative, student-led discovery through guided investigation, reasoning, and communication of mathematical ideas
• Replace front-loaded instruction with problem-solving, pattern recognition, and strategy development
• Foster a discovery-based approach where students actively construct mathematical understanding
• Purposefully integrate horizontal and vertical alignment, helping students connect concepts deeply and meaningfully
• Include built-in supports in the Teacher Edition for effective student questioning, discourse, exploration, and conceptual clarity

Each lesson includes multiple opportunities for student practice. Here are some examples of meaningful practice and targeted supports in Math Nation Florida:
Your Turn! provides students with a chance for true independent practice of the concepts they are learning in a given lesson.
Math Nation Florida is packed with practice that is designed to have students working collaboratively to solve problems, develop solutions, discover new ideas and strategies, engage in error analysis and much more. With peer-to-peer practice embedded throughout the program, students are provided with ongoing, meaningful collaboration opportunities.



Students may not have reached mastery when completing Try It. These problems are an opportunity to apply skills learned in previous components to more formal practice problems.

Check Your Understanding are a set of three digital practice problems available for students at the end of each lesson to inform and check for understanding.
The Guided Practice components provide opportunities for students to practice their skills in a structured, teacher-led setting. The intention is to practice together with guidance to maximize retention and understanding.
Activities include gallery walks, data collection, and games that allow the students to get additional practice in practical, engaging ways to leverage their critical and creative thinking skills.
Each lesson has a set of additional practice questions to provide another opportunity for students to independently practice what they learned in the lesson. These can be utilized in class or for homework.
Each lesson has a set of digital practice questions called Stepping Stones. These give students targeted practice that moves them toward mastery of lesson-level expectations. They can be used flexibly before or after the main lesson to reinforce understanding.
An additional Florida Independent Skills Practice Book helps students solidify and refine their skills, either in class or for homework. Practice books include embedded tutorial videos in English and Spanish so students and families have 24/7 support.

LITERACY AND LANGUAGE ROUTINES
Notice and Wonder
Students participate in a Notice and Wonder routine during this lesson’s Warm-Up. This positions students to consider how the scales of graphs impact the way data is presented visually and encourages students to draw conclusions about a data set from a graph.
MATHEMATICAL THINKING AND REASONING (MTR) STANDARD
MA.K12.MTR.7.1 Real-World Contexts
5.4.4 Your Turn! positions students to consider how information in the real world can be represented using graphs and coordinate planes. Students graph data relating to temperature in two cities and then NBA player statistics. Encourage students to draw conclusions about the significance of graphing data in the real world.
Throughout this lesson, students engage with the content in a variety of ways. As students graph data points on the coordinate plane, they visually represent the data. The 5.4.2 Try It and 5.4.3 Collaboration activities encourage partner discussion for students to process the learning verbally, providing auditory entry points for learners as well.
Notice and Wonder
Engage the class in a Notice and Wonder routine. Position students to discuss what they see on each graph, ensuring they understand both graphs represent the same data set and information. Students should begin to draw conclusions about the impact of scale on the graphs and consider which graph displays the data in a more understandable way.

Consider providing additional visual support for students, as the graph may be difficult to read given the number of point values and the scales on the x- and y-axes. It may be helpful to project the game board for the class so students can more clearly see where each point value is in relation to the scales, and/or to color-code each point value with the associated region of the gameboard.
If students are struggling to plot rational numbers on the gameboard, consider further scaffolding through questioning like:
• How can you plot decimal coordinates on a graph that uses a whole-number scale? How can you plot fractions on a graph that uses a whole-number scale?
• Do the coordinates need to be plotted accurately in this activity? Why?
Encourage partners to engage in mathematical discussion regarding their strategies.
• Who won? Was their strategy the same as yours?
• Did you have any issues plotting points or coming up with ordered pairs? Why?
• How did your knowledge of graphing points help you in this game?
• How did the scale of the axes impact the guessing game?

5.4.3 Collaboration: Hit or Miss
There are six shapes on the coordinate grid shown. Each partner will select one shape as their game piece. The object of the game is to guess which shape your partner selected before they guess yours. A hit means the point you guessed is inside their shape. A miss means that it is not. Keep your game board hidden from your partner during the game. Game Board

c. Label the point that represents the temperature in Princeton at midnight �������� . Which town was warmer at midnight, Princeton or New Haven? New Haven is warmer.
Students may graph negative fractions and mixed numbers. Consider posing questions to help students reason about where to plot the points, such as:
• How did you know where to plot the fractions whose denominators were more or less than halfway?
• If the time is in hours before or after midnight, what time is zero?
• Why is 2 the highest number on the y-axis?
If students struggle to answer questions 1c and 1d, consider asking the following to provide scaffolding:
• Which coordinates should be compared to determine the warmer town?
• Is a negative mixed number greater or less than a negative fraction?
• As temperatures go further negative, are they getting hotter or colder?
Students can label each column “x” and “y” or write out ordered pairs to help remember which axis each number is on.
MA.K12.MTR.7.1: Mathematics in Real-World Context
Students are graphing specific NBA players’ average points per game and how much they deviate from the average of the rest of the league. Consider asking:
• What does it mean when a coordinate is close to the x-axis on the graph?
• What does it mean when a player’s coordinates are higher on the graph?
• What does it mean when a player’s coordinates are lower on the graph?
Have students who finish early answer the following:
• What jobs do you think use this type of data?
• How would this graph be helpful to them?
• Are they jobs that you are interested in?
d. Explain how to determine which town you selected in Part C is warmer at midnight. Using the ��������-coordinate of both points, 2 10 is further up or greater than 7 2 meaning that it is warmer the other number.

This process allows students to think more analytically and to provide more detailed mathematical explanations.
MATHEMATICAL THINKING AND REASONING (MTR) STANDARD
MA.K12.MTR.5.1 Patterns and Structure
11.4.2 Activity allows students to use visual and mathematical patterns to identify common features of proportional relationships. Students analyze the tables and graphs to look for evidence of a constant ratio between each coordinate pair. Support students as they use their observations of patterns to generalize about proportional relationships.
Read and discuss the problems and scenarios aloud to assist students who benefit from auditory entry points. Emphasize the visual nature of the proportions for students who prefer visual learning methods.
Consider using the Five Practices for Orchestrating Productive Class Discussion to plan for how to facilitate a discussion that highlights various students’ voices and understanding as they further explore these relationships.
Notice and Wonder
Engage students in a Notice and Wonder routine to draw conclusions about the cost of peaches and plums based on the graph. After students complete the Warm-Up independently, consider asking questions like:
• How would you describe the cost-to-pound ratio of plums/ peaches?
• Why do you think cost is shown on the y-axis?
• What does this tell you about the relationship of the cost of an item to its weight?
If time allows during the debrief, suggest students mark where x=1 could be along the x-axis and then discuss with a partner what they notice about the y-values when x=1. Ask if they all had to use the same location for x=1 for this relationship to be true.

The graphs below show the cost, ��������, of buying �������� pounds of fruit. One graph shows the cost of buying �������� pounds of peaches, and the other shows the cost of buying �������� pounds of plums.

1. After looking at the relationships graphed, complete the table with one thing you notice and one thing you wonder.
One thing I notice is… One thing I wonder is… Answers will vary. Answers will vary.
2. Explain which fruit you think costs more per pound. Peaches cost more per pound because the line is steeper, meaning the price for 1 pound of peaches is higher on the �������� axis than for 1 pound of plums.

Several scenarios are described in the chart. Your teacher will give you two sets of cards showing tables and graphs.
1. Work with your partner to match a table of values and graph to each scenario. Write the matching table number and letter of the graph in the chart.
Written Description Table of Values Graph
a. T-shirts are priced $10 each at a store. There is a sale posted that says, “Buy two T-shirts, get the second one half-price.” The table and graph show the total cost, ��������, of �������� T-shirts.
b. A movie streaming service costs $8 49 each month. The table and graph show the total cost, ��������, for �������� months of the subscription.
c. A recipe uses 2 tablespoons of honey, �������� , for every 8 cups of flour, ��������.
d. Camping fees, ��������, at Blue Springs State Park in Volusia, FL include a $6 70 reservation fee and $24 per night, ��������
e. Rachel ran 6 laps in 18 minutes around the track at Riverview High School in Sarasota, FL. She notes the average number of minutes, �������� , that have passed after each lap, ��������
f. Kenneth is filling his fish tank with water at a flow rate of 1 6 gallons per minute. The table and graph show the number of gallons of water, ��������, after �������� minutes.
This activity is scaffolded to allow students to engage with it with their partner rather than be guided through by the teacher. There will be an opportunity to summarize and synthesize in the next component. Students may revise their thinking throughout the activity as they engage with each new question.
Observe and listen as students work with their partners. Make note of student ideas that you can ask them to share in the whole group for 11.4.3 Bring It Together. Additional scaffolding questions are provided, if needed, but this should be a primarily student-directed activity.
Support students as they analyze the tables and graphs by encouraging them to use their observations of patterns to form generalizations about proportional relationships.
2. Complete the statements using the words from the bank.
constant equivalent line ordered origin table
When two quantities are in a proportional relationship, the graph will include the , (0, 0) and the points on the graph will form a straight . The
pairs of the points on the graph match the pairs of values in the representing the same relationship. The ordered pairs in a proportional relationship are ratios. The value of the ratio is called the of proportionality.
3. Work with your partner to determine which scenarios from the card sort represent proportional relationships using the matching tables and graphs. Write the letter P next to the written description in the chart for each relationship that is proportional. Labeled in chart. The written descriptions for b, c, e, and f represent proportional relationships.
4. Use Graph D and the context it represents to complete the following parts with your partner.
a. Discuss why, for this context, it makes sense that every point on the line shown is possible.
b. Explain whether you think the graph representing this relationship will continue increasing every minute that passes.
The relationship should not continue increasing because a fish tank can only h old a set amount of water. Eventually, it would overflow. origin line ordered table equivalent constant
Question 4 and its parts provide an opportunity for the teacher to listen to students’ discussions, to observe whether they understand why the graph is continuous, and if they make connections to constraints on real-world contexts, which they explored in Unit 10. The intention of this question is to provide students with an opportunity to discuss and share their current thinking, not necessarily that they will all get this correct at this point.
The teacher can then use these observations from listening to the discussions about this question (along with the previous ones) to determine which areas may need more emphasis in the remainder of this lesson and Lesson 5, as students continue working on this benchmark.
*Note: It is not expected that students use the vocabulary of “continuous/discrete” or “constraint.” Students can use their own words to describe these concepts as they consider the real-world context.
If students are struggling with question 5, consider asking:
• If a relationship is proportional, what do we know about the ratios formed from each pair of values? (They are equivalent. (Point back to question 2.))
If students are still stuck, ask:
• If the ratios of each pair of values are equivalent for a proportional relationship, how will the ratios compare to each other if the relationship is not proportional? (They will not be equivalent.)
If the majority of the class is struggling with this, consider going over this question before or after the 11.4.3 Bring It Together.
5. Use Graph E and the table it matches to complete the following parts with your partner.
a. The points on Graph E form a straight line, but the situation does not represent a proportional relationship. Explain why it does not represent a proportional relationship. The ordered pairs in the table do not form equivalent ratios. Also, the line does not pass through the origin.
b. Use at least two ordered pairs from the table of values that matches Graph E to show why this relationship is not proportional.
Answers will vary.
This component is intended to be teacher-led and to summarize the key take-aways from the activity in 11.4.2 Activity.
Consider using observations from the activity to determine which key ideas need to be solidified or clarified. This could include discussing specific questions the student worked on. It should not be the teacher going through each question and telling the correct answer. Instead, the teacher might consider calling on students to share their thinking and respond to one another or restating something they heard while observing and asking students to discuss as the teacher leads the conversation toward solidifying these ideas.
Consider incorporating the Five Practices for Orchestrating Productive Class Discussion.


11.4.3 Bring it Together: Determining if a Relationship is Proportional Graphs representing proportional relationships have the following in common.
• The points that satisfy the relationship lie on a straight line.



• The line they lie on passes through the origin, (0, 0) Tables representing proportional relationships have the following in common.
• Each row in the table shows a ratio of the two quantities in the relationship.


• All of the ratios in the relationship are equivalent

LITERACY AND LANGUAGE ROUTINES
Which One Doesn’t Belong?
The 7.5.1 Warm-Up provides students with the opportunity to choose which graph they believe does not belong with the others. All of the options can be selected, so there is no wrong answer. This encourages all students to participate. The focus is having students justify why the graph they selected does not belong.
MATHEMATICAL THINKING AND REASONING (MTR) STANDARD
MA.K12.MTR.7.1 Real-World Contexts
Students graph linear representations of real-world contexts. They determine what information they need from written descriptions to graph the line. For example, in the 7.5.2 Exploration, students must determine the two points given in a written description and then graph the points and connect them to represent the linear relationship.
7.5.2 Exploration, 7.5.4 Guided Practice, and 7.5.5 Your Turn! require students to determine what information they need in a written description to graph the linear relationship. Have students underline, circle, or label the key information. Consider adding scaffolding questions to the 7.5.5 Your Turn! activity, similar to what is included in the 7.5.4 Guided Practice, to help students who are struggling determine the important information. Also, consider having students check their graphs using Desmos or graphing calculators.
Encourage students to use mathematical vocabulary when justifying their choice. Involve several students, ideally students who rarely participate. Participating has the potential to improve students’ efficacy and agency.
• Who used slope as the criteria to determine which graph doesn’t belong? (Call on a student to share.)
• Who used the y-intercept as the criteria to determine which graph doesn’t belong? (Call on a student to share.)
• What other criteria can you use to mathematically justify which one does not belong with the others?
Challenge students who finish early to think of a reason (and even multiple reasons) that would justify why each of the options do not belong. This will keep all students engaged while students who work at a slower pace determine one response.

The graphs of four linear relationships are shown.




1. Circle the graph that doesn’t belong. Explain your reasoning.
Answers will vary. An example would be the bottom right does not belong because it is the only one with a negative slope.

1. When plugged into a USB charger, cell phones charge at a constant rate until they get closer to being fully charged.
When Michaela plugged in her phone, the battery was at 16%. After charging for 15 minutes, the battery level was at 41%
This linear relationship can be represented by a graph where represents the number of minutes the phone was plugged in, and represents the percentage of the battery charged.
Harry said there is enough information from this context to find two points on the graph of this relationship.
a. Work with your partner to determine the coordinates of the two points.
Which point represents the phone’s charge when Michaela plugged it in?
Which point represents the phone’s charge 15 minutes after Michaela plugged it in?
( __0__ ,_16__ ) ( _15__ ,__41 )
b. Graph the linear relationship.
Consider encouraging students to highlight, underline, circle, or label the key information as a form of annotation while they read. Also, use a Think Aloud to help students understand how you determined the key information and used it to graph the line.
How did you determine the points on question 1? How do you know which quantity is x and which is y? Besides being a point on the line, what does (0,16) represent?

Battery Charge (Percentage)

Number of Minutes
c. What information was used to graph the relationship?
