Reason with shapes and their attributes.
- 2. Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) or three-dimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape.

Materials:

Procedure:

Encourage students to create different shapes on their “trees” using the rubber bands and tacks.
As they are creating, have students name the shapes they are making.
You can ask them to explain how they know it is a particular shape.

**This lesson is designed for students that have previous knowledge about shapes and their names. It is not intended to be an introductory activity.

Assessment:

Take anecdotal notes on what shapes the student was and was not able to name. Go back and review the ones they missed during one-on-one instruction or during small groups.
