Addition Within 100

Accurate addition depends on keeping tens and ones organised. You can use partitioning, a number line or a written method depending on the numbers.

Try This Strategy

  1. Start with the larger number.
  2. Add tens first when that makes the calculation easier.
  3. Add the ones and regroup if needed.
  4. Estimate the total before deciding your answer is correct.

Quick Self-Check

Ask: Is my answer sensible, and did I keep the place values aligned?
