Number Line Addition to 20 Worksheet

Using the Number Line at Home

Point to the first number in the problem and have your child place a finger there. Count each hop out loud together, moving one space to the right for every number being added. For 7 plus 6, that means six hops starting from 7, landing on 13. Saying each number out loud while hopping helps the counting stay accurate.

Making the Problems Easier or Harder

If counting to 20 feels like a lot, switch to numbers within 10 or even within 5. Pictures or a ten frame can give extra support as your child learns to hop along the line. Once adding feels steady, try subtraction on the same line. Hop backward instead of forward from the starting number.

What to Try Next

Once your child hops confidently to find sums within 20, move to bigger numbers next. Problems within 100, using tens and ones, can come after single hops feel easy. A ten frame worksheet can also help them see groups of ten before returning to the line. Mixing tools keeps the idea of adding the same while the tools change.
