Counting On


In kindergarten, your child will learn to count all the way to 100, by ones and by tens! But wait—Can he count to 100… starting from 29? Twenty-eight… Twenty-nine… Umm… twenty-ten?

Counting forward beginning at a given number, like 29, is a different skill than beginning at 1.

Numbers that end in 9 need 1 more to make a new group of 10. So, nine plus one equals one ten or 10. Nineteen plus one equals two tens or 20. Twenty-nine plus one equals three tens or 30.

This is a skill that needs lots of practice. So next time you’re in line at the grocery store, pick a number and have your child count on!
