Welcome to the Numeracy information evening for KS1
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?
