Educate your kids through something educating, or perhaps teach them a little something yourself, if you can.
Maybe the OP wants to have something for their kid to do while they're out running errands or something, as opposed to just being bored and having to follow behind mommy or daddy. Wouldn't that be a decent reason?
PS: No reason ever?
