Find every pair that makes ten
Seven and three, four and six, nine and one — the pairs that make ten are the ones first graders are meant to know cold. Hidden in a grid of digits, finding them is a game instead of a drill.
Pick a number, look at its neighbors, add.
A sum search worksheet generator, printable as a PDF. A ten-by-ten grid of digits with the target number in the middle, and a known number of pairs hidden in it: two numbers next to each other that add up to the target. The pairs run across on the easy level, across and down on the medium, and in any direction — diagonals too — on the hard. Ten is the default, and any target from 5 to 15 can be typed in. The sheet says exactly how many pairs there are, and that is the truth: every other square is chosen so that no pair appears by accident. The answer key rings each one.
