Cippenham Infant School

Teaching Maths

• Foundation Stage – Early Years Outcomes• Key Stage One (Year 1 and 2) – The National

Curriculum 2014

Children are expected to reach the Early Learning Goal (ELG) by the end of Foundation Stage.

Children are assessed against the criteria and judged to be:

‘Emerging’ – Still working towards the ELG‘Expected’ – Have met all the criteria of the ELG‘Exceeding’ - Are working beyond the criteria in the ELG

Foundation StageNumber/Shape, Space and Measures

2014-15

Year Two – National Curriculum 1988-2013Children are assessed using a numbered levelling system.

Year One – New National Curriculum 2014Children are assessed to be meeting expected criteria for their age group.

From September 2015 all children in KS1 will be taught using the new National Curriculum 2014

Practical MethodsAddition/Subtraction

0 1 2 3 4 5 6 7 8 9 1 0 1 1 1 2

Practical methods are best used when adding/subtracting single digit numbers, when answers do not go beyond 20.

A 100 square is used to add 2 digit numbers, when children are developing their understanding of place value.Children need to know ‘2’ in 23 is worth 20!

Written MethodsChildren need to understand partitioning to add/subtract 2 digit numbers.

25 = 20 + 525 = 10 + 10 + 525 = 10 + 9 + 625 = 19 + 6

Count on in tens and ones23 + 12 = 23 + 10 + 2Or36 + 53 = 53 + 30 + 6= 83 + 6= 89

Column Method (no carrying)

Partitioning and place value to add/subtract12 + 23 = 10 + 2 + 20 + 3= 30 + 5= 35

37 – 12 = 37 – 10 = 2727 – 2 = 25

Lets take a look at addition and subtraction!

Practical MethodsMultiplication/Division

• x

Pictorial methods - ArraysThree rows of 2…3 lots of 23 x 2

Counting repeated groups…

2+2+2+2 = 8 4 lots of 2 4 x 2 =

Sharing into equal groups

6 apple shared into 3 equal groups. How many in each group? 6÷3=2

Using a numbertrack or line…3x2=6“Put your finger on 0 and jump forwards in 2’s three times. The answer is the number you land on.”

Jumping back along a numbertrack or line in equal steps8÷2=“Put your finger on 8, jump backin 2’s. The answer is how many jumps it takes to get to 0.

Using and Applying

There are 3 buttons in a bag. I have 5 bags. How many buttons altogether?I have 10 grapes on my plate, my naughty brother ate 3! How many do I have left?I spend 35p at the shops. If I pay with 50p how much change will I get?There are12 chocolates and 3 children. If I share the chocolates equally, how many will they each have?

What are the important numbers?

How do you know?

?What are the

important words?What do you need to do to work out the

answer?

What can you do check your answer is

right?

The most important step for the children is to apply their knowledge in real life situations. When the children are asked questions they have lots of things to think about…

How could the children solve these problems? What calculation would they use?
