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
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
