MD2

2MD–2 Relate grouping problems were the number of groups is unknown to multiplication equations with a missing factor, and to division equations (quotative division).

4MD–2 Manipulate multiplication and division equations, and understand and apply the commutative property of multiplication.

5MD–2 Find factors and multiples of positive whole numbers, including common factors and common multiples, and express a given number as a product of 2 or 3 factors.

AS/MD2 Use a given additive or multiplicative calculation to derive or complete a related calculation, using arithmetic properties, inverse relationships, and place-value understanding.

KS3

• • • • Factors, multiples and primes use the concepts and vocabulary of prime numbers, factors (or divisors), multiples, common factors, common multiples, highest common factor, lowest common multiple, prime factorisation, including using product notation and the unique factorisation property

      • Use integer powers and associated real roots (square, cube and higher), recognise powers of 2, 3, 4, 5 and distinguish between exact representations of roots and their decimal approximations.
