Try it
- Draw your bridge plan.
- Build it. Try it.
- What happened? Change your plan and try again.
Make a paper bridge that lets a paper toy cross a gap. Use paper and blocks or folded paper supports. Draw your plan. Build it and try it. Record what happened. Change something for a reason and test again.
Your materials
Open the pupil workbook PDF. Use pages 19.

Teacher lesson plan
Learning goal
Plan, test, persist, and change strategy in a meaningful task.
Before teaching
Can choose a goal and engage with materials using needed support.
Model
Set a purpose: a paper bridge should let a paper toy cross a gap. Draw a plan, think aloud about supports, build, and test. Model noticing a collapse as information: “The middle bent. I can change the support.”
Guide, then apply
Children plan, make, test, and revise a bridge. Invite partners to agree roles and explain changes. Change the gap or toy only when the current task is understood; record the test condition.
Interpret the response
Several designs may work. Look for a goal, action based on a plan, observation, and a purposeful revision. If the child repeats an unsuccessful action, help notice what happened before proposing a strategy.
Support
Offer a choice of designs, pre-folded supports, visual steps, or a partner who carries out the child’s plan.
Extend when ready
Compare two designs under the same test condition and explain the tradeoff. Ask what evidence would change the child’s preferred plan.
Fresh check
Present a new support problem, such as keeping a paper sign upright. Observe whether the child uses a plan-test-revise cycle with less support.
Teacher plans PDF: page 19. Record exact support and revisit the idea later.
