We tried a number of different challenges this week. We filled grids with four different coloured counters and no counters of the same colour were allowed in the same row, column or diagonal. We had to get from the start square to the house square by visiting every square in the grid only once. We had to fill the triangle with three different coloured counters so that no counters of the same colour were touching. We played the coin game and we had to place four coins, one at a time, in an empty space and slide it straight along a line into another empty space. Two coins were not allowed to occupy the same space. We had lots of fun trying these challenges.
