Match the Same Number: 11 to 20

Seven big numbers from 11 to 20 sit down the left side: 11, 13, 15, 16, 17, 19 and 20. The same numbers appear in a different order on the right. Your child finds each number's twin and joins the pair with a line from dot to dot.

Most numbers from 11 to 19 start with a 1, so the second digit is what tells them apart. Pairs such as 13 and 15 or 16 and 19 look alike at a glance. Matching them teaches children to check both digits before deciding, not just the first one they see.

Say each number's name as your child points to it. If two numbers get mixed up, cover the 1 with a finger and compare the second digits.
