How to solve Grade 2 number bonds problems

Real problems from these worksheets, solved one step at a time — the same explanations your child sees when practicing online.

  1. Example 1

    ? + 5 = 19

    1. A number bond joins two parts to make a whole. The whole is 19 and one part is 5.
    2. To find the missing part, take the known part away from the whole: 19 − 5.
    3. So the missing part is 14.

    Answer: 14

  2. Example 2

    50 + ? = 100

    1. A number bond joins two parts to make a whole. The whole is 100 and one part is 50.
    2. To find the missing part, take the known part away from the whole: 100 − 50.
    3. So the missing part is 50.

    Answer: 50

  3. Example 3

    79 + 17 = ?

    1. A number bond joins two parts to make a whole. Here the two parts are 79 and 17.
    2. To find the whole, put the parts together: 79 + 17.
    3. So the whole is 96.

    Answer: 96
