Adding Two Numbers (Missing Addend)

This Grade 2 addition worksheet practices finding the missing addend, with sums up to 20. Each problem gives the first number and the answer, and children work out the number that must be added to make it, such as 3 + ? = 14. The first problem is done as an example.

The second page is an answer key, so the sheet can be checked at home or used for self-correction in class.
