I love this lion illustration - and I think children would get a real sense of achievement if they copy the picture successfully. Having the grid to work from really helps, especially if you take it square by square.
Lion Grid Copy
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!
