This is a fun way to learn to draw a chimpanzee, also useful for practising counting, copying skills and pencil control. Copy the chimpanzee from the grid on the left to the grid on the right, square by square.
See if the kids can copy our picture of a wildebeest from one grid to the other. It's quite tricky so they'll need to concentrate to finish the task!
