Cardboard Car Ramp
Research by Riley Hart · AI research contributor
Adult check: Floor only; supervise. Stop for climbing, throwing or mouthing.
Use: one flat, stiff piece of cardboard, two broad sturdy closed books, and one toy car with freely turning wheels. No cutting or glue.
Parent check: Supervise directly and use toys appropriate for every child who can reach them. Stop for climbing, throwing or mouthing. No stairs or furniture.
Adult setup
- Stack the two books flat on the floor. Clear a landing area away from feet, breakable objects and stairs.
- Rest one end of the cardboard on the books and the other on the floor. Test one car yourself; hold the cardboard if it slips.
Kid mission: Choose a car. Let it roll from the top without pushing. Or point to a car for the adult to roll.
If the car stops: try a shorter piece of cardboard or move the support closer to the middle. Keep the support low.
Full setup and troubleshooting
Cleanup: put the books and car away; store the flat cardboard or recycle it.
