Lesson 13

Describe Solid Shapes Around Us

Warm-up: Notice and Wonder: At the Market (10 minutes)

Narrative

The purpose of this warm-up is to elicit the idea that positional words and names of shapes can be helpful in describing objects, which will be useful when students find and describe solid shapes in their environment in a later activity. 

Launch

  • Groups of 2
  • Display the image.
  • “What do you notice? What do you wonder?”
  • 1 minute: quiet think time

Activity

  • “Discuss your thinking with your partner.”
  • 1 minute: partner discussion
  • Share and record responses.

Activity Synthesis

  • “What kinds of shapes do you see in the picture?”
  • “Do you see any objects that look like a sphere? Do you see any objects that look like a cylinder?”
  • As students share, prompt them to use positional words to describe the location of the object by asking “Where do you see that?”

Activity 1: Solid Shape Walk (15 minutes)

Narrative

The purpose of this activity is for students to identify and describe solid shapes in their environment (MP4, MP6). The shape walk can occur in many locations, such as a classroom, school, gym, playground, or library. Additional objects may need to be added to the environment to ensure that there are examples of a variety of solid shapes. Students may identify objects that are not exact examples of solid shapes. If this happens, consider acknowledging similarities between the shapes (“This shape has a point like a cone, but it is not a cone.”). Students use their own language to describe the solid shapes and are not required to use names of solid shapes. As students identify solid shapes, encourage students to describe the location of the object using positional words such as above, below, beside, and next to.

MLR8 Discussion Supports. Use gestures to emphasize the meaning of positional words. For example, gesturing to demonstrate the word below.
Advances: Listening, Representing
Engagement: Develop Effort and Persistence. Invite students to choose one or two solid shapes they will look for on their shape walk.
Supports accessibility for: Organization, Memory

Activity Synthesis

  • Invite students who used positional words to describe the location of shapes to share.
  • “____ saw a round light bulb below the lamp shade. It looked like a sphere.”
  • “_____ saw a book on the bookshelf. It looked like a box.”
  • Display image:
circular clock
  • “Which shape does this clock look like?” (Students say “cylinder” or hold up a cylinder.)
  • Display image:
Party hat in the shape of a cone
  • “Which shape does this party hat look like?” (Students say “cone” or pick up a cone.)
  • “In the next activity, we are going to use clay to make shapes that show the objects we saw.”

Activity 2: Make Shapes in the World (10 minutes)

Narrative

The purpose of this activity is for students to model objects in the environment using clay (MP4). Students choose a solid shape to represent the object and then make the shape out of clay.

Required Materials

Materials to Gather

Launch

  • Groups of 2
  • Give each student a piece of clay. Give students access to solid shapes.

Activity

  • “I saw a basketball on our walk. If I made it out of clay, which shape would it look like?” (Students point to the sphere or describe it.)
  • 30 seconds: quiet think time
  • Share responses.
  • “Pick one object that you saw on our shape walk. Choose the shape that the object is.”
  • 30 seconds: independent work time
  • “Use your clay to make the shape.”
  • 2 minutes: independent work time

Student Response

For access, consult one of our IM Certified Partners.

Activity Synthesis

  • Invite selected students to share the shapes they built.
  • As each student shares, ask the class to point to the solid shape that most looks like the object they built.
  • “Did anyone else see an object that looked like this shape?”

Activity 3: Centers: Choice Time (20 minutes)

Narrative

The purpose of this activity is for students to choose from activities that offer practice with number and shape concepts.

Students choose from any stage of previously introduced centers.

  • Build Shapes
  • Geoblocks
  • Counting Collections
  • Match Mine
  • Shake and Spill
