# Make a plan and improve it

Plan, test, persist, and change strategy in a meaningful task.

## Try it

1. Draw your bridge plan.
2. Build it. Try it.
3. 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.

## 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.
