As an elementary computer teacher, I have littles who can't read, and therefore don't know which keys are which on the keyboard. It's helpful for them to have a color coded keyboard that they can keep in front of them and match with their real keyboard. They ask, which is the period key? And I can say, the blue one! Eventually, they will get used to finding the keys on their own without having to ask me. I laminated them on cardstock so that they last.
