NOTES ON 2005 MEMORANDUM – Mathematics Education

1. There are 5 tiles in every metre because 1000 cm ÷ 200 cm = 5. So 15 × 10 = 150 tiles 2. Do not count the poles on the corners twice! 4 × 10 – 4 = 36 4. C – a rotation to the right through 90° 5. 4 reds – 10 greens – 3 purples. So 12 (3×4) reds – 9 (3×3) purples 6. nth row has 2×n – 1 dots, so 7th row has 13 dots 7.
