KS1 Maths – supporting your child at home. How we teach the 4 number operations. How you can support your child at home with maths.

Addition Phase 1 – adding by counting objects and finding how many there are in one or more groups. Phase 2 – adding by counting on from a number. * Number tracks! Phase 3 – partitioning numbers. Phase 4 – using known number facts. Phase 5 – beginning to use expanded written methods, moving onto column addition.

Phase 1 – adding by counting objects and finding how many there are in one or more groups = Phase 2 – adding by counting on from one number. * Number tracks!

Phase 3 – partitioning numbers. 8 =

Phase 4 – using known number facts = I know = is 1 less than 20 so the answer must be 1 less, therefore = …… = 100 I know = 10 so must = = I know double 3 is 6, so it must be 1 more than that.

Phase 5 – beginning to use expanded written methods, moving onto column addition

Subtraction Phase 1 – taking objects away or crossing pictures out. Phase 2 – subtracting by counting back from a number. * Number tracks! Phase 3 – partitioning numbers to take away from ones and tens. Phase 4 – using known number facts related to addition. Phase 5 – beginning to use expanded written methods.

Phase 1 – taking objects away or crossing pictures out = Phase 2 – subtracting by counting back from a number. * Number tracks!

Phase 3 – partitioning numbers to take away from ones and tens. 14 – 3 = – 3 = – 6 = 10 – 6 = 4 8

Phase 4 – partitioning numbers and using number lines to support subtraction. 71 – 24 =

Phase 5 – beginning to use expanded written methods. 5 – 2 = 3 20 – 10 = 10

Multiplication Phase 1 – counting in jumps of more than 1 (10, 5, 2 is the order that we learn these in) Phase 2 – making groups of the same and adding them together – repeated addition. Phase 3 – using arrays

Phase 1 – counting in jumps of more than 1 (10, 5, 2, 3 is the order that we learn these in)

Phase 2 – making groups of the same and adding them together – repeated addition. 4 x 2 = Children would have to count in 2’s to work out the answer before they could move onto the next phase of learning!

4 x 2 = Children can see that 4 x 2 = 2 x 4. Phase 3 – using arrays 2 4

Division Phase 1 – sharing objects between 2, 5 and 10 Phase 2 – grouping objects. Phase 3 – using known number facts

Phase 1 – sharing objects between 2, 5 and 10 6 ÷ 2 =

Phase 2 – grouping objects 6 ÷ 2 =

Phase 3 – using known number facts 8 ÷ 2 = If I know that 2 x 4 = 8 then 8 ÷ 2 must = 4

How you can support your child at home with maths. Make numbers ‘normal’ at home! Encourage children to handle money and work out what coins or notes they would need to use to pay for things. If they can – would they get any change and how much would they get? Look at the clock as often as you can – How long until…? What time do we…? How long was that…?

How you can support your child at home with maths. When cooking, encourage your child to weigh and measure different ingredients. Play number games. Make a number track game. When children are learning about numbers they need to see them as being linear so they can visualise them getting bigger and smaller. If you make a track game, try and make it on a straight line so that children can see them getting bigger and smaller.

How you can support your child at home with maths. Learn doubles and halves – if children grasp these early, it really helps! Number bonds up to and including 10. Can you think of a way that I haven’t thought of yet? When they are ready – times tables. Start with 10, 5 then 2. 10’s can easily be related to counting in 1’s. 5’s – hi- fives! Count how many fingers there are in groups of 5. 2’s – shoes! 1 pair of feet = 2 shoes. A great way to help children remember!
