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
