Activity book for Kindergarten lessons on composing and decomposing teen numbers, in terms of 10 and another number. Use the 10 as the last page so that students layer the numbers over the ones place to create teen numbers (modeled after hide zero cards).
Supports students work with place value, base ten understanding, and idea that teen numbers are composed of 1 ten and some ones.
Can be used in a variety of ways. I originally developed this to use during small group math instruction (station rotations or guided math model) on place value and teen numbers.
