Introduction

- These cards are designed to be used as mental and oral starters at Key Stages 2 to 4
- Ideally they should be laminated with the sample key questions on the back
- Please add key questions of your own and adapt the cards to reflect the ability of your students

SAMPLE KEY QUESTIONS

CORE

EXTENSION

- On your white boards, write down
- One bigger than t
- 2 greater than t
- 4 less than t
- Double t
- t less than 5

- On your whiteboards write down
- m bigger than t
- 4 less than double t
- 3 greater than t and then doubled
- t squared less than a

SAMPLE KEY QUESTIONS

CORE

EXTENSION

- On your whiteboards, write down
- If m = 2 what is the value of 5m ?
- How about m = 3 , 1, a half ……

- On your white boards, write down
- One bigger than 5m
- 2 greater than 5m
- 4 less than 5m
- Double 5m
- 5m less than 5
- Let m = 0.2 , 0.5 , a quarter ……

- On your whiteboards write down
- m bigger than 5m
- 4 less than double 5m
- 3 greater than 5m and then doubled
- 5m squared less than a
- Let m = 1.2, 0.6, …

SAMPLE KEY QUESTIONS

CORE

EXTENSION

- On your whiteboards, write down
- As many pairs of whole numbers as you can which add up to 6

- On your white boards, write down
- As many pairs of fractions which satisfy this equation

- On your whiteboards write down
- As many pairs of whole numbers which satisfy this equation – one number must be negative
- As above with decimals and fractions

EXTENSION

- On your whiteboards, write down
- As many pairs of whole numbers as you can which make sense in this equation

- On your white boards, write down
- As many pairs of fractions which satisfy this equation

- On your whiteboards write down
- As many pairs of whole numbers which satisfy this equation – one number must be negative
- As above with decimals and fractions
- Express x in terms of y

Using cards A5 to A8

- Give out the 4 cards to 4 pupils
- Ask pupils to stand at the front of the class showing the cards
- Give ‘x ‘ a value e.g x = 1
- Ask the pupils to put themselves in order lowest to highest value of the expression
- Repeat with other values, keep a record of card positions and ask for comments as x increases in value
- Suitable for Core and Extension classes

a , b , c , d…

SAMPLE KEY QUESTIONS

SUPPORT

CORE

EXTENSION

- These letters stand for numbers in a sequence. If the numbers go up in twos and a = 2, what are the other numbers?
- How about if b = 6
- d = 7 …..
- The numbers now increase by 3 each time …..

- The difference is 4 each time. If c = 11 what are the other numbers?
- If d = 5 ……
- Each number is double the previous number. If c = 12 what is a ?
- ……..

The difference is 3 each time. If a =1 what is the nth term?

If a= 4, use the nth term to find the 10th term …….
