Ok, this is a really cool idea for teaching decomposing/composing numbers! Rainbow to 10 Math Anchor Chart. Could be the best way to teach Composing/Decomposing Numbers ever!

I like this idea a lot for my Ss to practice number sense, but is greater/less than a concept they can understand or need to know? "The Lesson Plan Diva: FREE Dice Games Greater Than or Less Than"

This math station is called "in and out". The students simply drop a handful of cubes onto the in and out board. They record the number in the circle for the first addend and the cubes outside of the circle as the addend. Then solve the number sentence.
