Lesson 6
Compose and Decompose 10 with Pattern Blocks
Lesson Purpose
The purpose of this lesson is for students to compose and decompose 10 in multiple ways in the context of pattern blocks.
Lesson Narrative
In a previous unit, students solved Put Together/Take Apart, Both Addends Unknown story problems and decomposed 10 in more than one way. Students are not required to find all the ways to decompose 10, but they may use their understanding of how to find a number that makes 10 when added to a given number to help them find different decompositions.
