CCLS: Mathematics 2.0A, Operations and Algebraic Thinking
To help my students understand Composing and Decomposing Numbers, my students are taught how to play the "Composing Numbers MONSTER PUT-TOGETHER." Oh...they REALLY love this one. Basically, the kids work in partners. They each put a secret number of base 10 units into a cup (up to 10 units). They each spill out their "part" and and them together to get the "whole". Then they use the Monster Building KEY to determine what part of the monster they get to draw. For example, "compose a 2, add an eye," "compose a 15 add a nose."
This is a game they keep going back to time and time again when we have free choice math games. It's great for practicing facts!
