This interactive, self-checking activity is based on a groupwork task from SMP 11-16 (Cambridge University Press). In the original SMP version the clues were printed on cards. The cards were dealt out face-down to the members of a small group of four or five pupils.
The pupils were allowed to read out the information on any of their cards at any time and as often as they wished but they were not allowed to show their cards to anyone else.
The group then had to recreate the pattern using real counters on a printed grid.
There were 20 clues in the original SMP version.
