A story with choices
The Paper Bridge
Piko and Tosbi make a little bridge over a pretend river. Choose what they will try. No hurry, no penalty for changing your mind.
A river on the table
Piko puts two cardboard hills on the table.
What should they try first?
Try it on paper
With an adult, place two books a short distance apart on a table. Test a flat paper strip and a folded one. Which supports a small paper shape more steadily? This is a table model, not a real bridge.
