A few little ways
to play.
Start with the printable. See where their imagination takes it.
Make a paper bridge lab
Choose a building challenge from the bundle. Predict what will happen before testing, then keep your result. A bridge that bends gives you a useful clue for your next design.
Look for bridges outside
On your next walk, look for a footbridge or road bridge from a safe public place. Notice the shape, the supports, and what passes over or under it. Sketch something you recognize from the bundle.
Give the design a story
Decide what your capybara crew needs to carry across the river. Turn that little problem into a drawing, a conversation, or the beginning of a story.
Easy on your printer. Ready for their crayons.
Use the PDF that matches your paper, print in portrait, and check the preview before you start. Choose “Fit to printable area” if your printer clips the edges. Read our printing guide.
