Part A: Doubles Add. Each problem adds a number to itself.

  1. 1 + 1 = 2
  2. 2 + 2 = 4
  3. 3 + 3 = 6
  4. 4 + 4 = 8
  5. 5 + 5 = 10
  6. 6 + 6 = 12
  7. 7 + 7 = 14
  8. 8 + 8 = 16
  9. 9 + 9 = 18
  10. 10 + 10 = 20
  11. 11 + 11 = 22
  12. 12 + 12 = 24

Part B: Near doubles Add. Use the double, then add one more.

  1. 9 + 8 = 17
  2. 4 + 3 = 7
  3. 12 + 11 = 23
  4. 7 + 6 = 13
  5. 8 + 7 = 15
  6. 13 + 12 = 25
  7. 6 + 5 = 11
  8. 10 + 9 = 19
  9. 2 + 3 = 5
  10. 11 + 10 = 21
  11. 5 + 4 = 9
  12. 2 + 1 = 3

Part C: Mixed Add. Spot the double first.

  1. 4 + 4 = 8
  2. 2 + 2 = 4
  3. 6 + 5 = 11
  4. 7 + 7 = 14
  5. 9 + 8 = 17
  6. 3 + 2 = 5

Tips for teachers and parents

  • Learn the doubles in Part A first, out loud and in order: 1 + 1 = 2 up to 12 + 12 = 24.
  • For near doubles, find the double hiding inside. 8 + 9 is 8 + 8 = 16, plus one more: 17.
  • Point out that every double is an even number. If a doubles answer is odd, it is wrong.
  • Doubles lead straight into the 2 times table: 7 + 7 is the same as 2 × 7.

Common mistakes

  • Adding one to the wrong number in a near double, then counting the extra twice. Have the student say the double first, then "plus one."
  • Mixing up 6 + 6 = 12 and 7 + 7 = 14. Use real objects: an egg carton holds 6 + 6, and two weeks hold 7 + 7 days.

What to practice next

Use doubles and near doubles on the addition within 20 sheet.

Frequently asked questions

What are near doubles in math?

Two numbers that are one apart, such as 5 + 6. Students solve them by using the double, 5 + 5, and adding one more.

Why should children learn doubles?

Doubles are easy to remember, and they give a quick route to many harder facts. They also prepare students for multiplying by 2.

Does the sheet go past 10 + 10?

Yes. Part A covers doubles up to 12 + 12 = 24.
