Counters are a great resource that we can use in mathematics in a number of ways, for example to show patterns, to model our thinking or to keep track of moves. We have put together a number of activities that all use counters - can you work out the different ways in which the counters are used? Can you find some ways which aren't mentioned? Are there examples where stones or pebbles or … would
be just as good? Are there examples where the roundness of the counter matters? Are there examples where lots of the same thing is important?
