Teaching to do… “To add and subtract fractions, they must have the same denominator.”

Teaching to do… “There is a hierarchy of operations, with powers (and roots) at the top, then multiplication (and division), then addition (and subtraction).”

Teaching to do… “When adding numbers, we add the ones column, then the tens column, then the 100s column and so on…”

Teaching to understand… 756 + 583 139 1339 Notice collecting of same value, and exchange

Teaching to understand 3 × 5 + 2 × 7 15 + 14 29 Cant think about rods, so have to think about value. 3 × 7 + 2 × 7 5 × 7

Teaching to understand 3 7 + 2 7 = 5 7 3 5 + 2 7 21 35 + 10 35 = 31 35
