### Starter Cards - ALGEBRA

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

A1

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

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, …

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
• Express x in terms of y

CORE

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

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 …….
