Decomposing Numbers and Equations

In this math lesson, students learn about solving problems with multiple answers by decomposing numbers. The teacher introduces the concept of decomposition, explaining it as breaking apart numbers, using jelly beans and apples as examples. Students explore different ways to decompose the numbers six and seven, understanding that equations can be written in various forms. The lesson emphasizes creativity in math and provides visual methods to help students grasp the concept of decomposition.
