Aquadoodle and Home Schooling

My 4 year old wants to do everything his older brother gets to do, unless its school time.  He will fuss and whine about having school time, but just this week I took out our Aqua-doodle that has been hidden away in a box for months now, and let me tell you my preschool home schooling is going so well!  He has been loving drawing with water.  Today he shook the pen over the aqua-doodle to create stars, which went along with our question of the day: being about space and the Earth's weight.  He gets to learn the lower case letters, all his numbers, and learns how to draw: people, dogs, and houses (stick figure style).
