Lesson Plan

Composing/ Decomposing Numbers Up to 10


Two videos feature kindergarten lessons designed to support students as they compose and decompose numbers up to 10 using semi-concrete objects, such as counters and counting blocks. Students share different strategies and engage in a classroom discussion, surfacing that numbers can be viewed in multiple ways.

A document outlining the background and research on the content and standards, unit/lesson goals, and unit/lesson plan accompanies the video.
