Box -car toy

How about getting your toddler to make a fun toy on his own? I saw this from a site while surfing for some craft ideas. A simple and yet a challenging game for little one.

Materials: wide box, pen knife, car

Method:
1. Design some route on the surface of the box
2. Cut them according to the lines
3. Get your little one to move his car on the box

Challenge: Moving on the road to keep the car from falling
