Lesson objective: Compose three dimensional solids out of two dimensional shapes.

This lesson helps to build procedural skill with shape attributes. Three dimensional solids are used here because they support student understanding of the two dimensional shapes that are used to construct three dimensional solids. This work develops students' understanding that two dimensional shapes can be put together to make either a larger two-dimensional shape or they can be put together in a way that creates a three-dimensional shape. 

Students engage in Mathematical Practice 6 (attend to precision) as they look for specific two dimensional shapes in different three dimensional solids.

Key vocabulary:

  • circular
  • cube
  • cylinder
  • edge
  • face
  • rectangle
  • rectangular prism
  • square
  • square pyramid
  • triangle
  • triangular prism
  • triangular pyramid

Special materials needed:

  • pattern blocks (optional)
  • three-dimensional solid figures
