Tens and Ones

Play Digit Detective with your child. Write a mystery number up to 40 on a piece of paper, then turn the paper over to hide the number. Use place value language to provide clues about the number. For example, you might say, “The digit in the tens place is 1 more than 2. The digit in the ones place is 1 less than 2. What’s the number?” (31)

Order Whole Numbers

Play More/Less. For every number you say, ask your child to say the number that is 1 more, 1 less, 10 more, and 10 less.
Play Guess My Number. Think of a number, but don’t tell your child. Give clues such as using 1 more, 10 more, 1 less, or 10 less to help your child determine the mystery number. As he becomes more proficient, use clues that challenge him to cross the hundred. For example, “My number is 10 less than 42,” or “My number is 10 more than 39.”

One More/Less, Ten More/Less

Game: 10 More/10 Less

For example, say, "Count to 60, beginning with 27."

Counting Cards

Hundreds Chart

Use a hundreds chart to help your child skip count by 2s, 5,s and 10s.
Encourage your child to skip-count by twos and fives while he washes his hair, gets dressed, or does other daily chores. For example, ask him to start at zero and skip-count by fives up to 50 and back to zero: 0, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 45, 40, 35, 30, 25, 20, 15, 10, 5, 0.
Look for equal groups in your home that your child can identify and skip-count. For instance, when setting the table for dinner, notice equal groups of silverware. When folding laundry, skip-count pairs of socks.
