AIMS

To update our Parents on how Numeracyis delivered within KS1(KS2 on February 05/02/14)

To understand the importance of Numeracywithin the curriculum and the wider world

To enhance our children’s learning

To work together as a school and at home

To demonstrate progressive strategies in the 4 operations of number

To share resources and support ideas

How we can all help?Know what your child is learning in school?Learning objectives sent home half termlyPassportsPrepCommunicate with your child about Numeracy and their teacherYear 1 Numeracy diary (Year2)Numeracy involved in the ‘real world’Games and FunOwn opinions- positive and encourageKnow why Numeracy is importantOk to make errors, we learn from them, see where there is a misconceptionDon’t do it for them!Feel confident using the strategies that the children are usingWe didn’t learn it that way when I was at school, I’m not sure how to do it?Use the vocabulary the children understand and the taught strategiesAsk your child to explain how they’ve got to the answer

In our recent Tutor Time, we asked the children

‘Why do we learn Numeracy?’

Positive and important

3 categories• Helps us/ improve/ get better results/ answer

more quickly

• Jobs and future careers- get a better job, go to a better University

• Every day life- know what number house my friend lives, know how many things to box up, cook, play sport, shop, read the time………………

Parental perceptionsChild’s perceptions

Our aim, as a school, is to- Improve calculations and be able to do maths in our heads securely using a variety of strategies for the 4 operations of number and when the numbers start to get too big, to move onto using paper and pencil methods, more formal methods and then to use a calculator.

We want our children to be able to ask themselves….

1. Can I do this in my head?2. Can I do this in my head using drawings and

jottings?3. Do I need to use a compact/ expanded written

method?4. Do I need to use a calculator?

Addition, Subtraction, Multiplication and Division ( 4 operations of Numeracy)

So how do we teach our children to calculate?

Year 2 addition

A continuation of Year 1 methodsMental calculations• pairs with totals of 20• adding multiples of 10 to a given

number• adding pairs of 2 digit numbers• bridging multiples of 10

Year 2 addition

• Written methods

Partitioning into tens and ones:23 + 1223 + 10 = 3333 + 2 = 35

Year 2 addition

• Written methods

Using a number line to partition the second number23 + 12 = 23 + 10 + 2

23 33 35

Year 2 addition

• Written methodsAdding 9 or 11 by adding 10 and adjusting by 1 35 + 9 = 44 +10

35 44 45 -1

Year 2 subtraction

Mental calculations• Number bonds• subtracting multiples of 10 from

a given number• Subtract a pair of 2 digit

numbers by counting back, or counting up

Year 2 subtraction

• Written methodsFind a difference by counting up

42 – 39 = 3 +1 +2

39 40 42

Year 2 subtraction

• Written methodsSubtract 9 or 11, 19 or 21, 29 or 31 etc

35 – 9 = 26 +1

25 26 35 -10

Year 2 subtraction

• Written methods

Use known number facts and place value

37 – 22 =37 – 20 = 1717 – 2 = 15

3 X 4 =

Year 2 multiplication

Mental calculations• Count in 2s, 3s, 4s, 5s and 10s up to

12 x• Begin to understand that

multiplication is repeated addition• Double numbers to 50• Double multiples of 5 to 100

Year 2 multiplication

• Written methodsRepeated addition

2 + 2 + 2 + 2 4 x 2

Year 2 multiplication

• Written methods

Arrays

2 x 4 or 4 x 2

Division

Year 2 division

Mental calculations• Division as grouping – how many

groups of five in fifteen?• Using fingers – saying where a given

number is in the 2s, 5s, or 10s • Halve numbers to 40 and multiples of

10 to 100

Year 2 division

• Written methodsSharing

6 sweets are shared between 2 people. How many do they have each?

Year 2 division

• Written methodsGroupingThere are 6 sweets. How many people can have 2 each?How many 2s make 6?
