What children learn in Level 2

Counting back means saying the numbers that come before. It's like a rocket countdown! 10, 9, 8, 7.
You can count back from any number. Start at 53: 52, 51, 50, 49.
On the hundred chart, each step to the left is one less. At the start of a row, jump to the end of the row above: 51, 50, 49.
Your turn! Tap the number that comes right before 110.
Your turn! Start at 102 and tap the number line to count back 3.
Counting back: each number is one less than the one before.
