Take 1 large piece of cardboard, a big bucket of broken crayons, some tape, wooden blocks and all the Hot Wheels you can find. Combine them with a young boy, about the age of 4.
Add rivers, bridges, ponds, farms, roads, and railroads using the crayons. Build houses, barns, and hotels with the wooden blocks. Use a small piece of cardboard and lots to tape to make a bridge over the river.
Add cars, trains, tractors and heavy equipment. Oh, no! A wreck! Call 911, quick. Oh, good. Here come the fire trucks and ambulance. Whew!
Enjoy hours of fun!
