What does this painting have to do with math? Piet Mondrian reduced his subjects to colorful geometric shapes. In this painting, bold, black horizontal and vertical lines frame the colorful squares and rectangles in red, black, yellow, and more. Do any of the shapes seem similar? Do you notice that the smaller shapes are added together to create bigger shapes? How many shapes do you see in total?

FAMILY MATH

Module 1 Topic A

Classify to Make Categories and Count Dear Family, This newsletter will keep you up to date on what we are learning during math time. Use what you read to help your family talk about math and to practice math at home. You can expect a Family Math newsletter to come home every time our class begins a new topic. To begin the year, students are learning to sort objects into groups by color, type, shape, or size. After they sort, they count the objects in each group and tell how many.

Words We Are Learning sort count number

A student sorts by size and then counts how many in each group.

A student sorts by type and then matches a number to each group.

At-Home Activities Activity Idea 1 Whisper and Shout Count together from 1 to 10 by using a whisper voice. Then count again in a loud voice. Count to 10 a few more times. Vary the counting by using silly voices, taking turns, using gestures as cues to start and stop, or by counting while marching, hopping, or doing jumping jacks. As your child is ready, count to 20 or beyond.

Activity Idea 2 Sort Sorting is a way for students to organize their world by thinking about how things are alike and different. Give your child a set of household items that can be sorted into different categories. Kitchen utensils, laundry, or food make good choices. Let your child decide how to sort the objects. They might sort by color, shape, size. Or, they might use categories that are more personal, such as foods they like and foods they don’t like.

After they sort ask questions, such as: •

How did you sort?

Why did you sort this way?

How many are there in this group? Can you show me how you figured that out?

Module 1 Topic B

FAMILY MATH Answer How Many Questions with Up to 5 Objects Dear Family,

Students are learning to count groups of up to 5 objects. Counting each object only once can be a challenge, especially when objects are not lined up neatly. Students are using three strategies (touch and count, move and count, and mark and count) to help them organize and count accurately. Students are learning to use these strategies to determine whether they have enough when passing out classroom materials.

Words We Are Learning strategy enough line

Touch and count A student touches each object as they count.

Move and count A student picks up each sticker and moves it to the mat as they count.

Mark and count A student puts a mark on each white flower to show it has been counted.

At-Home Activities Activity Idea 1 Number Match Cut out the dot cards and number cards. Set aside the cards for 6–10 to use later. Hold up a dot card. Ask your child to tell how many dots. Then ask your child to find and hold up the matching number card. Have some fun with the number: Ask your child to stand up and hop, clap, or touch their toes the same number of times. (You can do it, too!) When cards 0–5 become easy for your child, move to cards 6–10. CHALLENGE: Show the dot card for only two seconds.

Can your child recognize how many without counting?

Activity Idea 2 Are There Enough? As part of everyday activities we often ask the question, “Are there enough?” Children may ask themselves this question as they set the table, have a tea party with stuffed animals, or share with siblings or friends. As your child participates in everyday tasks, have them practice counting out enough by using the strategies they learned in class.

Strategies to Count Students learn three counting strategies to help them count accurately and find how many are in a group.

Touch and Count

“1”

Say the number while touching the object. This strategy works best when objects and pictures are in a line.

Move and Count

“1”

Say the number while moving the object away from the ones that are not yet counted. This strategy is good for tracking objects that can be moved, especially when they are scattered.

Mark and Count Say the number while crossing off each object.

“1, 2, 3, 4, 5&quot;

This strategy is good for tracking which objects have been counted, especially when objects are not neatly lined up and cannot be moved.

FAMILY MATH Write Numerals and Create Sets of Up to 5 Objects Dear Family,

Students are learning to count out up to 5 objects from a larger group. This is harder than it seems! It can be hard to stop counting at a specific number and not keep counting the entire group! Students are also learning to write numbers 1 through 5 by using writing rectangles and practicing rhymes. Look for more information about this important skill on the back of this page.

Students count out 3 cubes from a larger group to match the number.

Students know there are enough cubes because each dot gets a cube.

Students show 4 by using drawings and numbers.

At-Home Activities Activity Idea 1 Count Out a Group Give your child a container of household items such as pasta, beans, or pennies. Show a number from 1 to 5 and ask your child to count out the same number of items. When groups of 5 become easy for your child, count out groups up to 10. Tip: Use the number cards from the set sent home with Family Math, module 1 topic B, or write the numbers 1–10 on index cards or sticky notes.

Activity Idea 2 Trace Numbers Practice writing numbers 1 through 5 by asking your child to trace each number with their finger. Use the rhymes on the back of this page to remind them how to write each number. Then make it a game by asking your child to trace a number on your back. See whether you can guess the number your child traced. Once your child has had time to practice each number, trade places and see whether your child can guess the number you traced. © Great Minds PBC •

Writing Rectangle The writing rectangle is a guide to help children correctly write numbers. The dot at the top of each writing rectangle gives children a place to start. Children are less likely to reverse their numbers when they start from the dot and keep their writing inside the rectangle. Eventually, they will be able to write numbers without the writing rectangle, but this tool provides them with structure to form numbers correctly from the start.

It is normal and developmentally appropriate for kindergartners to occasionally reverse numbers, or write them backward. Reversal of numbers should not be cause for concern. Instead, simply remind your child to begin at the dot and use the writing rectangle, while repeating the number rhyme (see below), to help write the number.

Starting numbers and letters from the top is an important habit for your child to build in kindergarten. It will help them write quickly and neatly when writing demands increase in later grades. A dot reminds children to start their numbers at the top.

Number Writing Rhymes

Module 1 Topic D

FAMILY MATH Decompose Numbers Dear Family,

Your child is learning about the relationship between numbers by sorting objects in more than one way. You might be thinking, Why are we still sorting? Sorting is a way to see how numbers can be broken into parts. For example, 5 bears can be sorted into 4 yellow bears and 1 red bear. The number sentence 5 is 4 and 1 represents this situation. 5 bears can also be sorted into 3 big bears and 2 small bears. Your child might say, “5 is 3 and 2” to represent this sort. Invite your child to show you counting the math way—a new way they are learning to count on their fingers.

Words We Are Learning number sentence

Sorting by color—5 is 4 and 1.

Sorting by size—5 is 3 and 2.

At-Home Activities Activity Idea 1 Sorting Different Ways Give your child a group of 4 or 5 items, such as toys, markers, or coins, that they can sort into different categories by color, shape, or size. Let your child decide how to sort. Then ask the following questions to help your child think about the total number of objects and the number in each group. •

How many ______ are there?

How many groups did you make?

How many are in this group?

Put the objects back into a pile. Ask your child to sort in a different way, and then ask the same questions. Did this sort result in the same number of groups?

Activity Idea 2 Nature Hunt Ask your child to find ways to sort or count objects while taking a walk or driving. For example, “I see 4 trees. 3 are big, and 1 is small.” If possible, collect objects like leaves, pine cones, or rocks for sorting and re-sorting later.

Counting the Math Way Using fingers for math is not babyish. In fact, young children who are able to represent numbers or problems on their fingers do better with counting, comparing numbers, and estimating in later years. Early work with fingers builds a part of the brain that is used for arithmetic. Students learn to “see” a representation of fingers in their brains even when they don’t use their fingers to solve problems. Your child is learning to count from 1 to 5 the math way, starting with their left pinkie finger and lifting one finger at a time until they reach their thumb.

In counting the math way, students can see and feel the number of fingers increase as they count from 1 to 10, moving from the left pinkie to the right pinkie without interruption. This left-to-right movement will be familiar when children begin to use tools such as the number path and, in later grades, the number line. Think of this work as push-ups for the brain!

FAMILY MATH Answer How Many Questions with Up to 10 Objects Dear Family,

Students are learning to count groups of up to 10 objects. It is harder to keep track of the count in these larger groups, especially when objects are scattered or in a circle. Students are practicing the three counting strategies (touch and count, move and count, and mark and count) to keep track of objects already counted.

COUNTING CONFIGURATIONS

Linear

5-Group

Array

Circular

Scattered

At-Home Activities Activity Idea 1 Beep Number Game Play Beep Number by saying a few numbers in order, replacing one of the numbers with the word beep. For example, if you say, “2, 3, beep, 5,” your child should respond, “4.” Use the number cards (sent home with topic B) in order as an extra support so your child can touch each number as you count. When your child is ready, invite them to say the numbers, while you guess the beep number.

Activity Idea 2 Count Toys Use toys or other household objects to make different counting configurations like the ones shown above. Encourage your child to touch and count or move and count the toys to find out how many there are.

5-Group Formations Why do we use 5-groups? You may have noticed that the dot cards (sent home with topic B) show 5 dots in a line. Groups of 5 help children visualize numbers 6 through 10 (5 and 1, 5 and 2, etc.). The dots make it easy to see each number as 5 dots plus some more dots.

6 7 8 9 10 Dots are not the only way to show 5-groups. Using fingers to count the math way emphasizes the relationship between 5 and the numbers 6 through 10 (5 fingers on one hand and some on the other). Organizing objects and drawings in groups of 5 can help children see this important relationship.

Module 1 Topic F

FAMILY MATH Write Numerals and Create Sets of Up to 10 Objects Dear Family,

Students are learning to count out up to 10 objects from a larger group. Just as with counting out a smaller group, it can be hard to stop counting at a specific number. Some students will want to keep counting the entire group! Students are also learning to write numbers 6 through 10 by using writing rectangles and practicing rhymes. Ask your child to share some reasons why we write numbers and share some reasons of your own!

Why Do We Write Numbers? - play restaurant - remember the count - make grocery list - share your phone number - faster than drawing - make a calendar - room numbers - keep score - play a game - make a birthday card

Students count out a group by drawing and by circling objects in a picture.

Students answer the question, “Why do we write numbers?” Students see their ideas recorded on a chart.

At-Home Activities Activity Idea 1 Hunt and Count Show a number card from 1 to 10 (sent home in topic B), and ask your child to find that many blocks, spoons, pennies (or any other fun item) in your home. When the hunt is over, have some fun with the number: Ask your child to hop, clap, or touch their toes the same number of times. (You can do it too!) When this becomes easy for your child, increase the numbers to 12, 15, and then 20.

Activity Idea 2 Write Numbers Practice writing numbers 0 through 10. Use the rhymes on the back of this page to remind your child how to write each number. Then make it a game by asking them to write the number in a rectangle of shaving cream (spread on a baking tray or the side of a bathtub). Make a dot at the top, using your finger or a bead, to help your child get started.

FAMILY MATH Analyze the Count Sequence Dear Family,

Students are exploring the sequence of numbers from 1 through 10. The number stairs make it easy to see that the next number in the count sequence is 1 more: “1; 1 more is 2.” Then “2; 1 more is 3 …” As they count back, students see the opposite, that each number is 1 less.

1-more number stairs

1-less number stairs

At-Home Activities Activity Idea 1 Number Detective 1. Use the number cards from topic B or cut out the number cards included with this letter. Mix up the cards and have your child place them in order from 0 through 10. 2. Once the cards are in order, flip a few cards so some numbers are hidden. Point to a flipped card and have your child use the numbers shown to figure out the hidden number.

Activity Idea 2 Number Match Game Mix the number cards and dot cards (included with this letter) together, and then lay 6 cards face up. Take turns matching cards that show the same number. Replace the matched cards with cards from the deck. Play until all cards are matched. Challenge your child to put the matched cards in order from 0 through 10.

Number Stairs In class, students build number stairs from 0 to 10 and find that the next number in the count sequence is 1 more. Number stairs allow students to visualize, or see, the pattern of 1 more in the forward counting sequence. They will also build number stairs from 10 to 0 to see that when counting back, each number is 1 less. We call this the 1-less pattern.

Why do children need to understand the pattern in the forward and backward count sequences? This understanding helps them know how many objects are in a group when they add 1 or take away 1. Without that understanding, a child might add a penny to a group of 24 and then count the whole group from 1. Students will see the number sequence represented on a number path and, in future grades, on the number line.

What does this painting have to do with math? Piet Mondrian reduced his subjects into colorful geometric shapes. In this painting bold, black horizontal and vertical lines frame the colorful squares and rectangles in red, black, yellow, and more. Do any of the shapes seem similar? Do you notice that the smaller shapes are added together to create the bigger shape? How many shapes do you see in total?
