What is Number Bond?

Number bonds are pairs of numbers that add together to make another (larger) number.

Often number bonds are used to help students learn pairs of numbers to reach common number boundaries, such as 10, 20, 50 and 100, etc.

Example: a number bond to 20 might be 16 + 4 = 20

Number bonds can also be used with subtraction facts, so if we know 16 + 4 = 20 then we also know that 20 - 16 = 4 and 20 - 4 = 16.

Number Bonds 2nd Grade

At a 2nd grade level, children should know their number bonds to 20.

They should also be able to fluently add and subtract within 20 using mental strategies.

If we look at this part-whole diagram above, we could write down two addition facts related to this number bond to 20, and also 2 subtraction facts.

  • 12 + 8 = 20
  • 8 + 12 = 20
  • 20 - 8 = 12
  • 20 - 12 = 8

However, because the '=' symbol means that the two expressions are equal, we swap the two sides over to write:

  • 20 = 12 + 8
  • 20 = 8 + 12
  • 12 = 20 - 8
  • 8 = 20 - 12

This last set of 4 addition and subtraction facts might seem obvious, but many students often struggle with missing number questions like 8 = 20 - ____.
