How to help

Count the tens first: 10, 20. Then count on the ones: 21, 22, 23. A number with more tens is more.

Watch for: Counting each stick as 1 instead of 10. Saying twenty-ten instead of thirty. Calling 19 more than 21 because 9 is more than 1.

At home: Bundle 10 spoons or sticks with a rubber band. Make numbers to 30 with bundles and loose ones.
