## Envision Math Common Core Grade K Answers Key Topic 13 Analyze, Compare, and Create Shapes

**Essential Question:**

How can solid figures be named, described, compared, and composed?

**enVision STEM Project:** How Do Objects Move? Directions Read the character speech bubbles to students. Find Out! Have students observe and describe how objects move using the terms roll, stack, and slide. Say: Objects move in different ways. Talk to your friends and relatives about everyday objects that are cones, cylinders, spheres, or cubes. Ask them how each one moves and whether they roll, stack, or slide. Journal: Make a Poster Have students make a poster that shows everyday objects that are cones, cylinders, spheres, and cubes, and then tell how each one moves.

Answer:

When a force pushes or pulls the object, the object will move in the direction of the force. Then the force can make things move, change shape or change their speed. Some forces are direct and happen when two things touch (like a foot kicking a ball)

Objects move in different ways. The motion of an object might be circular, curved, back-and-forth so on.

The object which has a curved surface that is all circular objects can roll.

Examples: Ball, lemon, orange, apple, football, etc.

The object which has a flat surface can slide.

Example: Rubber, laptop, duster, book, plate, etc.

Answer:

**Pick a Project**

Directions Say: You will choose one of these projects. Look at picture A. Think about this question: Have you eaten any circles or squares lately? If you choose Project A, you will make a kitchen shops poster. Look at picture B. Think about this question: Do you enjoy puppet shows? If you choose Project B, you will create a puppet show. Look at picture C. Think about this question: How would you describe the shapes in this quilt? If you choose Project C, you will design a patchwork quilt.

**Project : A
**POSTER :

**Project :**** B
**puppets are loved by young children for different reasons at different times in their lives. “Puppets have enduring appeal. Children can express these emotions too without upsetting anyone. Their puppet character is the one to feel these emotions. Playing with the emotions of the puppets helps to develop the characteristics of sympathy and empathy too. Children also experience this kind of expression when engaging in symbolic play. So in play schools puppet shows plays a vital role.

Materials required to play puppet show.

Paper ,glue, scissors, cardboards, markers etc.,

Use your scraps to make eyebrows, and lips.

Cut out lots of pieces. You can create lots of characters.

Use other paper with different colors and patterns to make clothing for your puppet.

Once the preparation is done with desired characters suitable for the story, by using our fingers, strings or holding sticks puppet show can be shown to the students.

### Lesson 13.1 Analyze and Compare Two Dimensional (2-D) Shapes

**Solve & Share**

**Directions** Say: Emily wants to figure out which shapes are behind the door. The mystery shapes that are behind the door have only 4 vertices (corners). Use the shapes shown above the door to help you decide which shapes are behind the door. Draw the shapes that match the clue on the door. How many shapes did you draw? Write that number next to the door. Now mark an X on the shapes that are NOT behind the door. Count those shapes and write the number. Look at the two numbers you wrote. Circle the number that is greater than the other number. If the numbers are the same, circle both numbers. Name the shapes that are behind the door.

**Guided Practice**

**Directions** Have students listen to the clues, mark an X on the shapes that do NOT fit the clues, draw a circle around the shape that the clues describe, and then tell how the shapes they marked with an X are different from the shape they drew a circle around. **1** I have 4 sides. I do NOT have 4 sides that are the same length. What shape am I? **2** I do NOT have 4 sides. I do NOT have any vertices. What shape am I?

Answer:

The shape which is marked with X is triangle as it has only 3 sides and 3 vertices.

The shape which is marked with circle is square and rectangle as they have 4 sides and 4 vertices.

The object with 4 sides is rectangle.

The object without 4 sides and vertices is circle.

Question 1.

Answer:

Question 2.

Answer:

**Directions** Have students listen to the clues, mark an X on the shapes that do NOT fit the clues, draw a circle around the shape that the clues describe, and then tell how the shapes they marked with an X are similar to the shape they drew a circle around. **3** Number Sense I am NOT round. I have less than 4 sides. What shape am I? **4** I am NOT a rectangle. I have o sides. What shape am I? **5** I have 4 vertices. I am a special kind of rectangle because all my sides are the same length. What shape am I?

Answer:

The shape which is not round and less than 4 sides is triangle. So students can mark X

The shape which is not a rectangle and no sides is circle. So students can draw circle around the shape easily.

The shape with special kind of rectangle and 4 vertices of same length is square.
