- Many ideas help find a good one.
- We test our solution.
- We improve it afterwards.
Words to know
something that needs fixing
an answer to a problem
to try something out
to make better
1. Discover: The muddy path
After rain, the path to the school gate is muddy and slippery. Class 2 asks, “How can we fix it?” They suggest stones, boards and a drain. They test stones and a plank bridge. Both work, but the plank is easier to walk on. “We improved our path,” says Yaw.
Think: Which idea would you choose?
2. Understand: Solving problems
Idea 1: Find the problem
Look and ask: what is wrong? A problem is something that needs fixing, like a muddy path or no shade.
Idea 2: Ideas and choice
Think of many ideas. Choose one that is safe, simple and uses things we have. Plan it and list materials.
Idea 3: Test and improve
Try the solution and test it. Does it work? What went wrong? Improve it and try again.
3. Worked examples
Example 1 (I show you): Problem
A muddy path.
- Wet and slippery.
- Needs fixing.
- Problem.
Answer: A muddy path is a problem.
Example 2 (We do it together): Ideas
Stones, boards, drain.
- Three ideas.
- Choose one.
- Test.
Answer: Many ideas help us choose.
Example 3 (You try): Improve
Plank slips.
Show the steps and answer
- Add grip.
- Test again.
- Better.
Answer: We improve after testing.
Did you know?
Engineers often try dozens of ideas before they find one that works well.
Why this matters
Problem solving helps communities be safer and cleaner.
4. Explore: Problem solver
Pick a school problem and plan a solution on paper.
- Name the problem.

Mastery and remediation
| Objective | Bronze (Developing) | Silver (Proficient) | Gold (Advanced) |
|---|---|---|---|
| O1 Identify a community problem | 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 |
| O2 Suggest ideas | 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 |
| O3 Choose and test an idea | 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: “The first idea is always best.” Compare ideas.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Explain how to solve a problem step by step.
- 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 practises problem solving. You do not need to be an expert to help.
- Spot a problem together.
- Ask, “What could fix it?”
- Plan a solution.
- 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: identify a community problem; suggest ideas; choose and test an idea; say how to improve it.
Prerequisite knowledge. Grade 1 ideas: caring for our environment, keeping clean and healthy and noticing how people use materials.
Materials. Paper, crayons and craft materials. 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. Prepare problem cards. Prepare 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). Show a muddy-path picture and ask, “What can we do?”
Explanation (10 min). Teach steps.
Guided activity (10 min). Learners plan.
Independent activity (10 min). Learners present.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. What is the problem? What is your idea?
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. “The first idea is always best.” Compare ideas.
13–15. Assessment questions, answer keys, marking scheme
Use the quiz, the 8-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 how to solve a problem step by step. 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.
