Halloween missing addend worksheet for 1st grade
A missing addend problem like 9 + _ = 14 asks children to think about addition backwards. It is an early step toward algebra and a strong way to build the link between addition and subtraction.
This single Halloween page has 20 addition sentences with one number missing, all with sums up to 20, and an answer key page. The Kindergarten-1st Grade Halloween pack ends with a missing-number section too, after the counting, picture and fact pages, so children meet these problems once the basics feel easy.
If a child guesses, ask them to check the guess by adding. That habit is worth more than the answer itself.
