Addition number search

Find hidden addition facts in a grid of numbers: three in a row where two of the numbers add up to the third.

About this worksheet

Unlike a word search, the hidden items are addition facts written as three numbers in a row, such as 5, 4, 9 or 9, 5, 4. Facts run across or down. Students check whether two of the three numbers add up to the third.

The grid hides exactly the facts the answer key lists and nothing else, so there are no accidental extras. Choose sums up to 10 or up to 20, the grid size and how many facts to find.
