What you’ll learn

All the Way to 100Rote count from 0 to 100 by ones, using tens as landmarks.Counting to 100 means saying the numbers in order, one more each time. The tens (10, 20, 30 …) act as signposts, and each number ending in 9 rolls over into a new ten family.
Start AnywhereCount on by ones starting from any given number.Counting doesn't have to begin at 1. From any number, keep adding one: 47, 48, 49, 50. The trickiest spots are the '9' numbers, where you bridge to the next ten.
Counting BackwardCount backward by ones down toward zero.Counting backward means saying one fewer each time, like a rocket countdown. From 10 you count 9, 8, 7 … down to 0. Backward counting builds toward taking away and subtraction.
