But it doesn’t have to be,
If I lie down on a piece of paper
You can draw a life-sized me!
If you’re confined for space or you can’t organise a big piece of paper, you can just do hands or feet. Alternatively, you can trace around other objects. But, as Boxie says, you can’t beat colouring in a full-sized person!
If you can’t find a big piece, try taping pieces together until you have a piece of paper bigger than the children! If you are using tape, try to keep it to the side you won’t be drawing on.
Decide beforehand, are you doing a different drawing with each child? Or are you all colouring in the one picture.
