Answer Key

Speedy Sums Answer Key

Addition Facts

  1. 5 + 3 = 8
    Thought Process: Starting at 5, count up 3: 5, 6, 7, 8.
  2. 7 + 2 = 9
    Thought Process: Starting at 7, count up 2: 7, 8, 9.
  3. 4 + 6 = 10
    Thought Process: Think of a number bond to 10. If you have 4, you need 6 more to make 10.
  4. 8 + 1 = 9
    Thought Process: Adding 1 is simply the next number in the sequence.
  5. 9 + 0 = 9
    Thought Process: Adding 0 means the number stays the same.
  6. 6 + 5 = 11
    Thought Process: You can think of this as 5+5=10, then add 1 more.
  7. 3 + 9 = 12
    Thought Process: You can count up from 9: 9, 10, 11, 12.
  8. 7 + 7 = 14
    Thought Process: This is a double fact.
  9. 8 + 5 = 13
    Thought Process: Count up from 8: 8, 9, 10, 11, 12, 13.
  10. 10 + 4 = 14
    Thought Process: Think of place value, adding 4 to the ones place.
  11. 2 + 11 = 13
    Thought Process: Count up from 11: 11, 12, 13.
  12. 12 + 3 = 15
    Thought Process: Count up from 12: 12, 13, 14, 15.

Subtraction Facts

  1. 10 - 3 = 7
    Thought Process: What number do you add to 3 to get 10? (7)
  2. 9 - 4 = 5
    Thought Process: What number do you add to 4 to get 9? (5)
  3. 11 - 5 = 6
    Thought Process: What number do you add to 5 to get 11? (6)
  4. 8 - 2 = 6
    Thought Process: Starting at 8, count back 2: 8, 7, 6.
  5. 12 - 0 = 12
    Thought Process: Subtracting 0 means the number stays the same.
  6. 14 - 7 = 7
    Thought Process: This is a double fact in reverse (7+7=14).
  7. 13 - 6 = 7
    Thought Process: What number do you add to 6 to get 13? (7)
  8. 16 - 8 = 8
    Thought Process: This is a double fact in reverse (8+8=16).
  9. 15 - 9 = 6
    Thought Process: What number do you add to 9 to get 15? (6)
  10. 18 - 10 = 8
    Thought Process: Subtracting 10 often means just changing the tens digit.
  11. 17 - 5 = 12
    Thought Process: Starting at 17, count back 5: 17, 16, 15, 14, 13, 12.
  12. 19 - 8 = 11
    Thought Process: What number do you add to 8 to get 19? (11)
