1. Warden Hill Infant School
Maths Activity Workshops

2. Diennes
We use Diennes to help us understand place value and for adding and taking away numbers.

3. Using jottings for Addition
= 59

4. Using jottings for Subtraction
= 114

5. Inverse
The pupil can recognise the inverse relationships between addition and subtraction
Pupils can use this to check calculations and work out missing number problems
Δ − 14 = 28
= 42

6. Fractions
Children need to be able to find fractions of a length, a shape and a set of objects and understand the role of the numerator (top number) and the denominator (bottom number).
First children find half (½) or a quarter (¼) of an amount by sharing objects:
Children move on to using jottings (images, pictorial representations) as below: 1/3 of 6 = 2 ● ● ●
½ of 8 =4
¼ of 8 =2

7. ¼, ½, ¾, 1 Children need to be able to count in fractions eg:
And explain that:
Can your child tell you
½ of any even number to 24?
1/5 of any multiple of 5 up to 60?

8. Can children work out the problem by selecting the correct operation?
Problem Solving
Can children work out the problem by selecting the correct operation?
There are 20 balloons
7 fly balloons fly away.
How many balloons left?

9. Problem Solving
The pupil can solve word problems that involve more than one step.
Which has the most biscuits, 4 packets of biscuits with 5 in each packet or 3 packets of
biscuits with 10 in each packet?

10. Multiplication
Children should be able to understand and calculate multiplication as repeated addition supported by practical resources as below: Children show how multiplication calculations can be represented by an array using practical apparatus and jottings to support their understanding:
= = 15

11. Repeated addition can easily be shown on a number line:
5 x 3 =

12. Commutativity
Children should know that 3 x 5 has the same answer as 5 x 3 and can be represented on a number line and also using jottings:
Jottings to show
3 x 4 = 12
4 x 3 = 12
