Student lesson
- Engineers solve problems.
- The steps are ask, imagine, plan, create, test, improve.
- Failure gives useful information.
- Good designs are improved many times.
Words to know
a person who designs solutions to problems
a plan for how to make something
a first model to test
to repeat and improve
1. Discover: The wobbly desk
Kojo’s desk wobbles. Instead of complaining, he asks what is wrong, imagines fixes, plans one, tries it, tests it and improves it. “That is how an engineer thinks,” says his teacher.
Think: What would Kojo do if the first fix failed?
2. Understand: Design steps
Idea 1: The steps
Engineers ask about the problem, imagine ideas, plan the best one, create a model, test it and improve it.
Idea 2: Repeat
The process is a loop. A test that fails shows what to iterate. Most real products are improved many times.
Idea 3: Teamwork
Engineers work in teams, share ideas and listen to the people who will use the design.
3. Worked examples
Example 1 (I show you): Order
Steps.
- Ask.
- Plan.
- Test.
Answer: Ask, imagine, plan, create, test, improve.
Example 2 (We do it together): Explain
Failure.
- Shows a weakness.
- Gives data.
- Leads to change.
Answer: Failure is useful.
Example 3 (You try): Apply
Wobbly desk.
Show the steps and answer
- Find cause.
- Try a wedge.
- Test.
Answer: Fix and retest.
Did you know?
The Wright brothers tested hundreds of wing shapes in a homemade wind tunnel before they flew.
Why this matters
The design process turns problems into useful solutions.
4. Explore: Paper tower
Design a paper tower that holds a small toy at 20 cm using only paper and tape, then test and improve it.
- Ask what is needed.
- Sketch two ideas.
- Build the best one.
- Test and improve.
Think about it: what did you notice?
What did you notice? The first version needed changes.

|---|---|---|---|
| O1 Name the steps | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |

Courseversity badge thresholds (overall quiz score): Gold = 90–100%; Silver = 80–89.9%; Bronze = 70–79.9%. A badge is never a full record of progress.
If a learner struggles
- Find the misconception: “Failure means stop.” Use it.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Explain the design process.
- Guided practice: work through one example together and let the learner try the next one.
- Reassess: use the quiz again or the worksheet.
- Move on when the learner shows Silver-level evidence independently.
For parents and guardians
In this lesson your child follows the engineering design process. You do not need to be an expert to help.
- Spot a problem.
- Ask “What could we try?”
- Celebrate mistakes.
- Ask “how do you know?” after each answer, and listen.
- Praise effort, not only right answers. Mistakes are how we learn.
- Ten to fifteen minutes a day is better than one long session.
Teacher package
1–5. Objectives, prerequisites, materials, preparation, duration
Lesson objectives. Learners will: name the steps; order the steps; explain why we repeat steps; apply the process.
Prerequisite knowledge. Grade 4 ideas: testing fairly, improving a design and using simple technology.
Materials. Paper, tape, small toy, ruler. Low-resource options: use chalk or charcoal on a board or wall, drawings in the sand, and objects from the classroom instead of printed materials.
Preparation. Gather materials.
Suggested duration. 45–60 minutes. It can be split into two shorter sessions.
6–9. Teaching procedure, explanation notes, guided and independent activities
Introduction (5 min). Present a wobbling table and ask, “How would you fix it?”
Explanation (10 min). Teach the steps.
Guided activity (10 min). Learners build.
Independent activity (10 min). Learners improve.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. What step are you on? What did the test show?
Teacher explanation notes. Start with real objects and safe, hands-on observation. Then talk about what was seen, then draw and write. Always say “how do you know?”. Keep to the safety notes, and use local, safe materials.
10–12. Differentiation, formative assessment, common misconceptions
Support. Use real objects and pictures, short sentences and a partner. Let learners point, show or draw instead of writing. Extension. Ask learners to find a new example at home and explain how they know.
Formative assessment. Listen to learners read and explain, ask “how do you know?”, and check the independent work.
Misconceptions. “Failure means stop.” Use it.
13–15. Assessment questions, answer keys, marking scheme
Use the quiz, the 10-mark exam practice and the worksheet on this page. All answers and marking guides are in the answer sections above. Re-check every answer before use.
16–19. Remediation, enrichment, homework, teacher reflection
Remediation. Explain the design process. Enrichment. Look for one new example near your home or school, draw it and explain it to someone. Homework. See above.
Teacher reflection. After teaching, record: which ideas learners understood; which misconceptions occurred; which activities worked; which learners need more practice; and what to improve next time.
