Worked examples

Real problems from the practice worksheets, solved one step at a time.

  1. Example 1

    ? + 2 = 3

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

    Answer: 1

  2. Example 2

    2 + 1 = ?

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

    Answer: 3

  3. Example 3

    2 + ? = 3

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

    Answer: 1
