Do you remember when you were child and you go to school? And most of us didn't like maths, geometry, science, physics, etc.?
If I had a child I would teach him this subjects with coloured images, so he can have more fun and he can remember better what he studied.
A book full of images is certainly more atractive than one full of signs, especially for the very youngest. Maybe is more expensive, but kids will adore the characters. Or why not teaching maths with strip cartoons?
