Year 5: Multiplication and Division

New Maths Curriculum (2014): Year 5 objectives.

Pupils should practise and extend their use of the efficient written methods of short multiplication and short division. They apply all the multiplication tables and related division facts frequently, commit them to memory and use them confidently to make larger calculations.

They should use and understand the terms factor, multiple and prime, square and cube numbers.

Pupils should interpret non-integer answers to division by expressing results in different ways according to the context, including with remainders, as fractions, as decimals or by rounding (e.g. 98 ÷ 4 = 24 r 2 = 241/2 = 24.5 ≈ 25).

Pupils use multiplication and division as inverses to support the introduction of ratio in Year 6, for example, by multiplying and dividing by powers of 10 in scale drawings or by multiplying and dividing by powers of a 1000 in converting between units such as kilometres and metres.

 Identify multiples and factors, including finding all factor pairs Solve problems involving multiplication and division where larger numbers are used by decomposing them into their factors A new resource to help teach this objective will be added soon.
