About factor pairs worksheets

Each number has a row of boxes, one pair for each factor pair, written smallest first. You can give the smaller factor in every pair, so students only fill in the partner, or leave both boxes empty for a full challenge.

The number of pairs tells students when they are done. The solved example shows the check-the-numbers-in-order method: try 1, 2, 3 and so on, and stop when the pairs meet in the middle.
