Tray-top marble run
Your child designs it and watches it work. That “I made this happen” feeling builds real confidence.
You’ll need: cardboard tubes cut in half lengthways, masking tape, a large marble or ball, a small cup, a lap tray
How to play
- Make two or three half-tube channels.
- Ask “Where should this one go?” and let your child point to direct you.
- Tape each channel where they choose, sloping downwards, with the cup at the bottom.
- Release the marble together. “Faster or slower next time?” Adjust and go again.
