In this video, Amy Berns, a Kindergarten teacher, engages her students in decomposing numbers. The students use gummy bears and a visual representation of a book shelf to model different ways to decompose the number 5 into two or more parts. Students are asked to find and represent all possibilities for decomposing the given number into two parts, to share their thinking, and to write an equation to correspond to the representations.
