Expectations Year 5 • Solve one step and two step problems involving whole numbers and decimals and all four operations, choosing and using appropriate calculation strategies • Use efficient written methods to add and subtract whole numbers and decimals up to 2 places. • Refine and use efficient written methods to multiply and divide up to HTU and decimal numbers
Expectations Year 6 • Solve multi step problems and problems involving fractions, decimals and percentages; choose and use appropriate calculation strategies at each stage • Use efficient written methods to add and subtract whole numbers and decimals, to multiply and divide whole numbers and decimals. • These are a guide. • We work from your child’s maths skills • revisiting where needed • challenge where needed
Addition • Using a range of resources • Counters, number lines, number squares • Blank number line for addition
Addition: Partitioning 47 40 + 7 + 7670 + 6 __ 110 + 13 = 123

+4 +2 18 20 24 Subtraction: Counting On • 24 – 18 = This is the same method people use in shops when counting out your change. e.g. You need to pay 65p. You give a £1 coin. They say ‘65…70….90…£1’. = 6 22.4 – 17.8 = = 4.6
Subtraction – Expanded method 4 5 7 -2 4 8 40 400 50 7 -200 40 8 200 00 9 We would start by showing how to partition and calculate this using apparatus (e.g. hundreds, tens and units blocks). = 209
Subtraction – Short Column method 743 – 367 = 600 130 6 ‘3 700 40 3 700 40 ‘3 7 4 ‘3 - 300 60 7 - 300 60 7 - 3 6 7 300 70 63 7 6 Video example

Multiplication (Written methods)
MultiplicationStage 1: Recap Informal recording may look like this: 14 x 3 10 x 3 = 30 4 x 3 = 12 30+12 =42
Multiplication Stage 2 An expanded method which uses a grid. It links directly to the mental method as an alternative way of recording the same steps. 38 x 7 = x 30 8 210 + 56 7 210 56 266
Multiplication: Grid method 56 x 27 = x 50 6 1000 20 1000 120 120 7 350 42 350 + 42 1512
Multiplication Stage 3: Expanded short T U 38 X 7 56 (7 x 8) 210 (7 x 30) 266
Multiplication: Expanded method T U 56 x 27 42 (7 x 6) 350 (7 x 50) 120 (20 x 6) + 1000 (20 x 50) 1512
Stage 4: Short multiplication The recording is reduced further, carrying digits below the line. T U 4 5 x 6 2 7 0 3
If children make errors with carrying digits or adding in this way, we would then get them to return to the expanded method.
Stage 5: two-digit by two-digit 56 x 27
T U 5 6 x 2 7 3 9 2 + 1 1 2 0 1 5 1 2 1 34 x 23 = 4 1
Begin with practical examples - sharing (10 ÷ 2 =) 10 objects shared between 2 people grouping (10 ÷ 2= ) 10 objects grouped into groups of 2 Using multiplication knowledge (very important to think about division when practising times tables)
Grouping using a number line 30 ÷ 6 =

Three girls have a quarter of a cake. What fraction is left? ¼ x 3 = ¾ 1 - ¾ Or 4/4 – 3/4 = 1/4
