Using cards a5 to a8 l.jpg

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

  • 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 …….
