03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | 1 square centimetre | Area of a square is side times side, and 1 times 1 = 1 square centimetre. |
| 2 | 15 square centimetres | Area of a rectangle is length times width, and 5 times 3 = 15 square centimetres. |
| 3 | 16 square centimetres | Four times four = 16 square centimetres. |
| 4 | 4 centimetres | 24 divided by 6 = 4 centimetres, since length times width gives the area. |
| 5 | 40 square centimetres | Eight times five = 40 square centimetres. |
| 6 | 12 square centimetres | Each square is 1 square centimetre, so 12 squares make 12 square centimetres. |
| 7 | 7 centimetres | Seven times seven = 49, so each side is 7 centimetres. |
| 8 | 3 squares | 12 divided by 4 = 3, so 3 squares fit exactly. |
| 9 | 6 squares | Each row fits 9 divided by 3 = 3 squares in 2 rows, giving 6 squares. |
| 10 | 24 square centimetres | Area uses multiplication, and 6 times 4 = 24 square centimetres; 20 comes from the perimeter method. |
04 What to do after marking
- After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
- Repeat the same item two days later; move to the next paper only when both attempts are correct.
- Parents only need the answer and note columns; there is no need to explain every item.
