Nine subtraction problems in a 3x3 grid, all within 18. 4 of 9 problems cross 10.
The nine problems on this sheet: 3 - 1, 8 - 5, 17 - 12, 11 - 5, 17 - 10, 18 - 9, 14 - 6, 18 - 8, 12 - 8.
No timer and no score — a child works at their own pace and the picture is the only judge. Because each answer from 2 to 10 appears exactly once, a child who has placed six pieces can deduce the rest. Having them write the answers first keeps it arithmetic.
Useful as cover or substitute work: the sheet corrects itself and the answer key is included, so an adult who does not know the class can run it.
The answer key lists all nine results, which is the quickest way to check the level before printing. Note that crossing 10 only comes up in the subtraction here; adding over ten does not appear on this type of sheet. The completed picture shows a Kitchen Tools scene.
