We are working toward a firm understanding of our teen numbers (numbers 11-19) in kindergarten!
This is an example of a math mountain. There are 12 Tiny Tumblers on top of the 12 Math Mountain. If ten roll down one side, we know there will be two on the other. We practiced this will all of the teen numbers, with 10 ALWAYS rolling down one side. The kids did a GREAT job on their math mountains and most kids are writing their numbers correctly too!
