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?

Module 2 Topic A

FAMILY MATH Analyze and Name Two-Dimensional Shapes Dear Families,

Students are learning to recognize and describe two-dimensional, or flat, shapes, including by using the number of straight sides and corners a shape has. Students also learn that triangles, rectangles, squares, hexagons, and circles are all closed, or have no gaps. These defining attributes are then used to sort figures into categories of examples and nonexamples. For example, “I know this is a triangle because it has 3 straight sides and 3 corners. This one is not a triangle because 1 side is curved.” Students also practice using position words by listening to directions and placing shapes above, below, behind, in front of, next to, or on top of an object.

Words We

Triangles

Not Triangles

Are Learning describe triangle rectangle circle square hexagon

A student touches and counts each corner and side of a triangle.

A student decides whether a shape has all the features of a triangle.

A student listens to directions and uses acquired understanding of position words to place shapes.

At-Home Activities Activity Idea 1 Almost or Exactly Like Shape Search Cut out the five flat shape cards. Ask your child to choose any card and to look around the room for something that is exactly like that shape. Then ask your child to find something that is almost like that shape. Have your child share why their object is exactly or almost like that shape. Now, you take a turn and share why it is exactly or almost like that shape. For example: An exact rectangle: a picture frame, a television screen, a door. An almost rectangle: a pillow, a toaster, a sandwich.

Activity Idea 2 Where Is It? Use the shape cards to play “Where Is It?” Ask your child to close their eyes. When their eyes are closed, hide one of the cards near or on a toy and give clues as to where the shape is. For example, “The square is next to your teddy bear.” Encourage your child to use the clues to find the shape. Then ask your child to choose a card and hide it while you close your eyes. © Great Minds PBC •

Module 2 Topic B

FAMILY MATH Analyze and Name Three-Dimensional Shapes Dear Families,

Your child is learning to describe three-dimensional, or solid, shapes. This includes learning to distinguish between flat and solid shapes, naming the shapes, and counting faces, edges, and corners. In class, students use their own words as well as math language to describe the features of solid shapes. They begin to match solid shapes to the flat shapes that they see in them.

Words We Are Learning flat shape solid shape pyramid sphere cube cone rectangular prism cylinder

A student sorts by flat and solid shapes and then matches a number to each group.

A student looks at a group of objects and finds the solid shapes that they resemble.

At-Home Activities Activity Idea 1 Almost or Exactly Like Shape Search Cut out the six solid shape cards. Ask your child to pick a card and to look for an object that is almost like that shape. Then ask your child to find an object that is exactly like that shape. Have your child share why the object is exactly or almost like that shape. Now you take a turn and share why it is exactly or almost like that shape. For example: Exactly like a sphere: a baseball, a soccer ball. Almost like a sphere: a pair of socks rolled up, a blueberry, a piece of puffed cereal.

Activity Idea 2 Find Another One Use the real-world solid shape cards to play this game. Start by shuffling the cards and spreading them out picture side down. Take turns picking up two cards at a time to see if

EUREKA MATH2 Tennessee Edition

K ▸ M2 ▸ TB

they show the same type of solid shape. This game uses only the cylinder, rectangular prism, and sphere. If the cards match the same solid shape, you keep them. If they don’t match, put them back facedown. Describe why the photos match or do not by using language about the features. For example: If you choose the photos of the book and box on your turn, you might say, “These are rectangular prisms. They both have 6 faces and 8 corners.”

What Makes a Solid Shape? Students learn these features for each shape.

CYLINDER 2 round or circle faces No corners Smooth around middle Looks like a can CONE 1 round or circle face 1 tip

SPHERE No edges or faces No corners or tips Rolls like a ball

FAMILY MATH Construct Shapes Dear Families,

Your child is working to apply what they have learned about flat and solid shapes to create models of shapes by using materials such as clay and straws. The act of making shapes helps children understand the most important features of the shapes. They also discover how one shape can help build a different shape, and they explore how shapes can fit together like a puzzle.

K ▸ M2 ▸ TC ▸ Lesson 14

EUREKA MATH2

Fill in the puzzles.

Students build models of 5-sided flat shapes with straws or craft sticks.

Students build models of solid shapes by using straws and clay.

PROBLEM SET

Students create two new shapes by using 1 hexagon and 2 rhombuses.

At-Home Activities Activity Idea 1 Shape Builder Invite your child to explore household materials to build a shape. Consider using toothpicks or building blocks for shapes with straight sides. Your child can use string or cooked spaghetti to explore shapes with curved sides. Consider asking, “What is the name of that shape? How do you know?” For an extra challenge, give your child clues to build a specific shape. For example, “Here is the clue. The shape I’m thinking of has 4 sides and 4 corners. Can you build it?”

Activity Idea 2 Make a Silly Face Use the empty pumpkin shapes to play this game. Start by drawing one shape at a time on the pumpkin from the choices at the top. Try to use as many different shapes as possible at least once. You can combine the shapes to make new ones. This isn’t meant to be a a contest but an opportunity to have creative fun with your child. © Great Minds PBC •

So Many Ways to Make a Flat Shape Students put shapes together and try to see how many different ways they can make a new shape. This is an added challenge because the outline of the shape is shown and students have to manipulate the shapes while staying within the boundary of the new shape.

RHOMBUS 2 triangles

TRAPEZOID 1 triangle and 1 rhombus 3 triangles

HEXAGON 2 triangles and 2 rhombuses 6 triangles 3 triangles and 1 trapezoid 2 trapezoids 3 rhombuses

MATH IS EVERYWHERE Do you want to compare how fast you and your friends can run? Or estimate how many bees are in a hive? Or calculate your batting average? Math lies behind so many of life’s wonders, puzzles, and plans. From ancient times to today, we have used math to construct pyramids, sail the seas, build skyscrapers—and even send spacecraft to Mars. Fueled by your curiosity to understand the world, math will propel you down any path you choose. Ready to get started?
