Addition and subtraction are mixed on the same sheet, so a child has to read the sign each time: 1 + 1, then 22 - 12. Switching between the two is a separate difficulty from the arithmetic itself. Filed under Grade 1, though the numbers here go above 20 — closer to Grade 2 or Year 3. In Grade 1 it suits children already secure within 20.
The nine problems on this sheet: 18 - 9, 1 + 1, 12 - 7, 2 + 6, 22 - 12, 19 - 12, 3 + 3, 1 + 2, 1 + 3.
A wrong answer breaks the picture, so a child sees the mistake straight away and can fix it without waiting for an adult. It shows where they went wrong, not why. Every sheet uses the same nine answers, 2 to 10. Some children will match by piece shape instead of calculating — asking them to read two facts aloud settles it.
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 christmas scene.
