Building Simple ModelsActivities & Teaching Strategies
Active learning works for this topic because building simple models transforms abstract design ideas into concrete, testable forms. When Year 3 students physically shape cardboard or drag simple shapes in software, they see their creative thinking take form, which strengthens their ability to communicate and refine solutions. Hands-on prototypes also let students immediately spot flaws and opportunities, making the design process visible and engaging.
Learning Objectives
- 1Design a low-fidelity physical model of a proposed solution using craft materials.
- 2Create a low-fidelity digital model of a proposed solution using a drawing or block-based coding tool.
- 3Explain how a simple model communicates the function of a design concept to an audience.
- 4Compare the advantages of physical models versus digital models for representing specific design ideas.
- 5Evaluate the effectiveness of a model in conveying a design solution based on peer feedback.

Pairs: Cardboard Shelter Builds
Pairs select materials like cardboard, straws, and tape to construct a simple shelter model for a scenario, such as animal protection. They test stability by adding weights like books, then label parts to explain functions. Pairs swap models for peer testing and feedback.
Prepare & details
Compare the benefits of physical versus digital models for different projects.
Facilitation Tip: During Cardboard Shelter Builds, circulate to ask guiding questions like, 'What part of your shelter will hold the books? Show me how it works.'
Setup: Varies; may include outdoor space, lab, or community setting
Materials: Experience setup materials, Reflection journal with prompts, Observation worksheet, Connection-to-content framework
Small Groups: Digital Low-Fi Sketches
Small groups use a simple drawing app or paper to create digital-style prototypes of a class project, like a recycled toy. They add annotations for moving parts and share screens. Groups vote on clearest models and suggest one digital tweak.
Prepare & details
Explain how a simple model can convey complex ideas.
Facilitation Tip: In Digital Low-Fi Sketches, model how to use basic tools (e.g., shapes, colors) to show function, not decoration.
Setup: Varies; may include outdoor space, lab, or community setting
Materials: Experience setup materials, Reflection journal with prompts, Observation worksheet, Connection-to-content framework
Whole Class: Model Comparison Challenge
The class builds two versions of the same idea: one physical with craft items, one digital via shared tablet sketches. Students test both for ease of change and clarity, then chart pros and cons on a class poster. Discuss findings as a group.
Prepare & details
Design a low-fidelity model of a proposed solution.
Facilitation Tip: For the Model Comparison Challenge, set a two-minute timer for groups to agree on one feature that makes their models clear and one that could be improved.
Setup: Varies; may include outdoor space, lab, or community setting
Materials: Experience setup materials, Reflection journal with prompts, Observation worksheet, Connection-to-content framework
Individual: Quick Clay Prototypes
Each student molds air-dry clay into a low-fidelity model of a personal design solution, like a lunchbox organizer. They photograph it with labels and present to a partner. Revise based on one piece of partner advice.
Prepare & details
Compare the benefits of physical versus digital models for different projects.
Facilitation Tip: During Quick Clay Prototypes, remind students to keep shapes simple and focus on the core idea they're testing.
Setup: Varies; may include outdoor space, lab, or community setting
Materials: Experience setup materials, Reflection journal with prompts, Observation worksheet, Connection-to-content framework
Teaching This Topic
Teachers should treat this topic as a cycle of build-test-share, not a single outcome. Start with low-fidelity materials to keep focus on function over finish. Use routines like think-pair-share after building to help students articulate ideas before refining them. Avoid over-directing; instead, ask open questions that guide students to notice what works and what doesn’t in their own models.
What to Expect
Successful learning looks like clear communication of a design idea through a low-fidelity model, supported by simple explanations or labels. Students should be able to explain what their model does and why they chose its materials or shapes. Peer feedback should focus on clarity and function, not perfection.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Cardboard Shelter Builds, watch for students who focus on making their shelter look like a real house rather than showing how it holds books.
What to Teach Instead
Prompt them with, 'Point to the part that keeps the books off the floor. Could a simple box or shelf show this better than detailed walls?' Then ask them to rebuild with that focus.
Common MisconceptionDuring Digital Low-Fi Sketches, watch for students who add colors, patterns, or extra shapes that distract from the core function.
What to Teach Instead
Ask, 'What does this shape do? Does adding glitter help someone understand how the swing moves?' Guide them to delete non-functional elements and label key parts.
Common MisconceptionDuring the Model Comparison Challenge, watch for students who assume the 'best' model is the one that looks most realistic or detailed.
What to Teach Instead
Have groups compare function first: 'Which model makes it easiest to see how the bridge supports weight?' Then ask, 'What details do we actually need to show that?'
Assessment Ideas
After Cardboard Shelter Builds, give each pair a sticky note and ask them to write: 'One thing our shelter does well: ______. One thing we would change next time: ______.' Collect notes to check for focus on function.
During Digital Low-Fi Sketches, pause the class for a quick discussion. Ask: 'When you built your shelter, you could hold it. When you sketch a digital model, what can you still show well? What can’t you show?' Have two students share their answers to assess understanding of each model type’s strengths.
After the Model Comparison Challenge, have students use a simple checklist to give feedback to one peer. The checklist should ask: 'Does the model show how it works? Is it easy to understand? What is one label or shape you would add to make it clearer?' Collect the checklists to assess clarity and explanatory thinking.
Extensions & Scaffolding
- Challenge early finishers to build a second version of their model using different materials, then compare how each version tests the same idea.
- Scaffolding for struggling students: Provide labeled templates (e.g., a simple house shape with slots for doors/windows) or sentence starters like, 'This part shows... because...'.
- Deeper exploration: Invite students to research real-world shelters or playgrounds, then sketch or build a new model that combines two ideas they found.
Key Vocabulary
| Model | A representation of an idea or object, used to test or show how something works before building the final product. |
| Low-fidelity model | A basic, simple model that quickly shows the main idea of a design, often made with readily available materials or simple digital tools. |
| Prototype | An early model or sample of a product built to test a concept or process, which can be improved upon. |
| Design concept | The main idea or plan behind a solution to a problem, before detailed design or construction begins. |
