This sheet practises taking away with numbers up to 20. 4 of 9 problems cross 10, which is what makes one sheet harder than another at this stage.
The nine problems on this sheet: 7 - 4, 15 - 9, 12 - 3, 11 - 6, 20 - 12, 10 - 3, 9 - 7, 20 - 10, 7 - 3.
Because the sheet corrects itself, a child can fail privately and try again — which matters for children who are anxious about getting maths wrong. One mistake does leave the picture incomplete, so for children who find that discouraging it works better in pairs, or checked after every three pieces.
Best suited to a math center or station rotation, where a child needs to finish something without an adult and without anyone marking it. A complete picture is a five-metre glance-check across the room.
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 At the Supermarket scene.
