About Adding Three or More Numbers

What this skill is

Adding three or more numbers teaches children to group addends efficiently (looking for pairs that make 10 or doubles) to add multiple numbers accurately (e.g., 4 + 7 + 6 = (4+6) + 7 = 10 + 7 = 17).

When children learn it

Adding three addends is introduced in 1st grade and expanded in 2nd grade, aligned to 1.OA.A.2.

Teaching Tips

  • Look for addend pairs that equal 10 first and join them.
  • Cross off each addend number as it is incorporated into the running sum.

Common Mistakes

  • Accidentally skipping one of the addends in long list columns.
  • Adding numbers sequentially without looking for easier make-ten pairings.
