Count down and fill in the missing numbers. Kindergarteners count back from 20; first graders count back from any number up to 100.

Kindergarten

Grade 1
Counting backwards is harder than it looks — many children who count up fluently freeze when asked to count down from 15. Yet backward counting is the skill that makes subtraction intuitive: taking one away is just saying the number that comes before.
Each question shows a descending sequence with two numbers missing. The kindergarten level counts down from numbers up to 20; the grade 1 level starts anywhere up to 100. Print a fresh randomly generated sheet whenever you need one.
Counting backwards prepares children for subtraction, elapsed time, and mental math. It shows they truly understand number order instead of having memorized a forward-only chant.
The count-back-from-20 sheets fit kindergarten. The count-back-from-100 sheets fit grade 1. Both are also useful review for older children who find subtraction difficult.
