Math: My kids like to play Zip Horse. While riding in the car, everyone keeps an eye out for horses! Every horse (not donkeys) is worth 2 points. Solid white horses are worth 5 points. Whoever gets to 21 points wins the game. Kids learn to be observant, and learn what combination of numbers makes 21 points (such as 8 regular horses and one white horse make 21, or 3 white horses and 3 regular horses. I guess this is math, taught as soon as a child can find horses. Parents help with adding until the child can add on his own.
