Composing and Decomposing Shapes and Area
This module describes the concept of how composing and decomposing shapes supports other mathematical concepts, the idea that smaller units can be combined to form larger units and vice versa, concepts about area that students can work on before learning to calculate area, and how tiling and partitioning can be used to prove the calculation of area.

Perimeter, Volume, and Mass
The basic concepts of perimeter, volume, and mass will be discussed. Participants will understand how to use the Anchor, Think and Do, Apply lesson format when planning instructional activities using perimeter and volume as an example. Using the Anchor, Think and Do, Apply format, participants will match Essential Elements to purposes for instruction and determine anchor activities that match purposes.
