Key things to remember
1. The importance of developing rapid recall of number facts such as times
tables, doubling and halving and quick working out of fractions is vital
2. The development of mental strategies begins before written methods and
then runs parallel to them – it is the thing that children will use most in life
3. Formal methods are important but not at the expense of understanding
(efficient methods are used increasingly as the children get older)
4. The language of and discussion in maths is important i.e. an important term
for the children to know with multiplication is product as this is used a lot
Multiplication
Informal groups > numberline > arrays
Multiplication
Grid method (efficient) > formal (efficient)
Multiplication examples from Y1/2 and from Y6
There are 4 apples in each pack.
Work out the number that is halfway between
27 × 38 and 33 × 38
Show your working.
(this one might be easier than it looks)
Mrs Pullen buys 3 packs of apples.
How many apples does she buy?
Division
Dividend – the big number
Divisor – the small number
Note about remainders:
remainders as numbers in KS1
and Y3. Increasingly expressed
as fractions as children move
into Y5,6. E.g. 36 ÷ 5 = 6r1 in
Y3 but 6 and 1/5 in Y5
