I read this idea in my FamilyFun magazine: Tape a "lesson" to the back of the front seat (ie. so the kids can see it). The picture in the magazine had a money sheet listing coins and what they were worth. I could adapt this idea to put up words we're working on, math problems, or shapes and colors. I would even try putting up copies of my favorite art pieces. Something to look at, something to think about, a little change from the "Alphabet game".
