A substantial Coding Without Screens project

Branching shape path is a Team project designed to stay available for about 60 minutes. Children investigate design thinking, sequencing, systems reasoning and iterative problem-solving through a concrete shared task rather than completing identical work.

Educational purpose

This invitation gives children opportunities to develop design thinking, sequencing, systems reasoning and iterative problem-solving. Look for the decisions children make, the language they use to explain an idea and the evidence they notice after trying it. A finished model is optional; the planning, testing and discussion are valuable parts of the experience.

Goal

Design a working branching shape path solution for a clearly identified user or task.

Materials

Large paper, markers, clean construction materials, tape, picture cards, role cards and optional blocks or loose parts. Add arrow cards, user cards, testing tokens and a simple design-record sheet.

Set up

• Present the branching shape path as a specific problem with more than one possible solution.
• Create a building table and a separate route or feature-testing zone.
• Offer designer, builder, tester, recorder and user-feedback roles.

Run the activity

1. Choose who will use the branching shape path and state the exact task it must complete.
2. Draw the key parts or sequence with arrows, labels and a clear start and finish.
3. Build the smallest version that can test the most important feature.
4. Ask a tester to use it without extra explanation; record where the design fails or confuses.
5. Change one feature and explain how the evidence supports the revision.

Educator prompt

Who is this for, what must it do, and how will a tester show whether it works?

Adapt participation

Use a ready-made user card, fewer construction choices, picture sequences and a partner builder or scribe.

Extend the challenge

Add a size, material, accessibility, energy or route constraint and justify the trade-off made.

Safety

• Check tools, materials, floor space and supervision against local service procedures.
• Keep walkways clear and use only clean, lightweight construction materials suitable for the children present.
• Participation, observing and an alternative activity remain available choices.

Reflection

Which test revealed the most useful problem, and how did the design respond?

Printing notes

The two-page A4 guide follows the same clean format as the printable physical games. Page two includes a cut-off quick-reference card that can be stored with the activity materials or laminated.
