Addition and subtraction are mixed on the same sheet, so a child has to read the sign each time: 1 + 1, then 23 - 14. 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: 1 + 1, 16 - 13, 16 - 8, 23 - 14, 5 + 1, 3 + 4, 6 + 4, 8 - 3, 9 - 5.
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. The answers are always 2 to 10, one per piece, so ask children to solve all nine before placing any — otherwise the last few can be found by elimination.
Nine problems is about five to ten minutes for a secure child, which fits early finishers and morning work. It practises something already taught rather than introducing anything new.
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 4th of July scene.
