1. Discover: Three ways to a clean field
Mei proposes more bins, Abu suggests a tidy-up rota, and another group suggests a poster campaign. “How do we choose?” asks Ms Smith. They list criteria: fair, safe, low cost, effective and supported by pupils. They fill a decision matrix with scores and evidence from their survey. “Bins score high on effect but cost money,” says Mei. “Posters are cheap but may not change habits alone,” says Abu. “A mix may be best,” says Ms Smith.
Think: What is the risk of choosing a solution without checking evidence?
2. Understand: Evaluating proposed solutions
Idea 1: Criteria
A solution is a way to improve an issue. To compare solutions, we agree on criteria: is it fair, safe, low in cost, effective, good for the environment and supported by those affected? Is it feasible with the time and resources we have?
Idea 2: Comparing
A decision matrix lists solutions in rows and criteria in columns and gives scores supported by evidence. Check for side effects, such as extra work for the caretaker or cost to families. Try combining solutions, or running a small pilot test.
Idea 3: Justifying
Explain your choice using the criteria and evidence: “We chose bins plus a rota because our survey shows pupils support them and the cost is low.” Admit limits and say how you would check if it works.
3. Worked examples
Example 1 (I show you): Define
Criteria.
- Think.
- Say.
- Check.
Answer: Standards for judging.
Example 2 (We do it together): Define
Feasible.
- Think.
- Say.
- Check.
Answer: Possible with resources.
Example 3 (You try): Give
A side effect.
Show the steps and answer
- Think.
- Say.
- Check.
Answer: Extra work for staff.
Did you know?
Many organisations test small pilot projects before spreading a solution widely.
Why this matters
Evaluating solutions helps us choose actions that really work and are fair.
4. Explore: Decision matrix
Choose two or three solutions for a school issue. Make a matrix with five criteria. Score each from 1 to 3 with a reason. Add up, discuss side effects and justify your choice in three sentences.
- Choose.
- Score.
- Discuss.
- Justify.
Think about it: what did you notice?
What did you notice? Evidence beats guessing.

If a learner struggles
- Find the misconception: “The cheapest solution is always best.” Check all criteria.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Make a solutions chart.
- 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 compares solutions to a school issue. Please talk about weighing choices at home. You do not need to be an expert to help.
- Weigh options.
- Ask for evidence.
- Respect other views.
- 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: define solution, criteria, feasible, effective, side effect; develop criteria; compare solutions with evidence; justify a choice.
Prerequisite knowledge. Grade 5 ideas: sources, evidence, perspectives, civic participation and community issues.
Materials. Matrix sheets. 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 matrix sheets.
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). Tell the three ways to a clean field story.
Explanation (10 min). Teach evaluating solutions.
Guided activity (10 min). Decision matrix.
Independent activity (10 min). Discuss.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. How can we judge which solution is best?
Teacher explanation notes. Start with a picture, story, map or local example. Then talk about what was seen, then draw and write. Always ask “how do you know?” and invite more than one view. Treat every family, culture and community with respect, and never ask learners to share private information.
10–12. Differentiation, formative assessment, common misconceptions
Support. Use pictures, maps, real objects and short sentences, and let learners work with a partner. Let learners point, show, act or draw instead of writing. Extension. Ask learners to find a new example from their own community 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 cheapest solution is always best.” Check all criteria.
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. Make a solutions chart. Enrichment. Find one new example near your home or school, draw or write about 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.
