• Adding means putting together two numbers to make a bigger number.
  • When we add 7, we start with a number and then count 7 more.
  • We can use fingers, number lines, or objects to help us add.

  • 3 + 7 = 10
    (Start at 3, count 7 more → 4, 5, 6, 7, 8, 9, 10).
  • 5 + 7 = 12
    (Start at 5, count 7 more → 6, 7, 8, 9, 10, 11, 12).
  • 7 + 7 = 14
  • 9 + 7 = 16

👉 To add 7, put your finger on the first number and jump forward 7 steps.

Example:

  • For 4 + 7 → Start at 4 → jump 7 steps → you land on 11.

  • 2 + 7 = ___
  • 8 + 7 = ___
  • 10 + 7 = ___
  • 12 + 7 = ___

Adding 7 is the same as adding 5 + 2.
Example:
6 + 7 = 6 + (5 + 2) = 11 + 2 = 13

  • You can count on to find 7+8.
  • It is easier to start with the larger number. So, start at 8. Count on 7 times.
  • You end at 15.
  • 7+8=15

  • You can also add using doubles plus one.
  • Remember the doubles fact 7+7=14.
  • Notice that 7+8 is 1 more. That makes 15.
  • 7+8=15
  • You can count on to find 7 + 2.
  • Start at 7 and count on 2 times.
  • You end at 9.
  • 7 + 2 = 9
  • You can count on to find 2 + 7.
  • It is easier to start with the larger number. So, start at 7. Count on 2 times.
  • You end at 9.
  • 2 + 7 = 9
