Why paint by numbers are so popular?
Though I never considered paint by numbers to be an educational tool, I now see that it just might be if you start young enough. If your child already know their numbers and colors, you are just giving them something fun to do, not that there is anything wrong with that, but if you give this to a younger child, you have just handed them a learning tool. They have to match the colors up with the numbers, and this gives them practice with not only knowing what their colors are, it helps them recognize numbers.
