2Flat vs. Solid: The Six Solids

2D shapes are flat — they live on paper. 3D shapes are solid — you can hold them! Meet the six solids:

Cube

Rectangular Prism

Sphere

Cone

Cylinder

Pyramid

3Name That Solid

Write the name of each solid. Use the word bank: cube, sphere, cone, cylinder, pyramid.

Theo is packing a box with blocks. He has 4 cubes, 3 cylinders, and 2 cones. How many solids that can ROLL does he have? (Hint: which of these solids have a curved surface?)

My thinking:

rolling solids
