Fraction equivalents collective memory

This collective memory includes fraction to decimal equivalents. There are also some different shapes with elements shaded in, and labelled using decimals, fractions and percentages. Pupils can be in small groups, with 1 person from each group coming to see the collective memory (the slide is timed at 15 secs). The other members of the group can then take it in turns to come up and look for 15 secs. The pupils try to replicate the collective memory poster on their own sheets. Then swap with a different team and have pupils peer asses.
