A worked example that makes each step visible.
A proposed Year 8 mathematics practice resource for introducing a two-step linear equation through a short length puzzle.
Challenge
Illustrative brief: create a short mathematics practice resource for Year 8 learners, using a ribbon-length puzzle to introduce a two-step linear equation. The learning-content service is intended for UK schools, tutoring providers, education publishers and edtech teams. This proposed context is synthetic; it does not describe a real client project.
Approach
Start with the objective of representing and solving a two-step equation, then shape it into a worked example that makes the key idea easier to teach and practise. Use the puzzle to write 3x + 5 = 20, undo the operations one at a time, and substitute the result back into the original equation as a check. AI can support exploration and drafting; mathematical judgement, classroom context and human review shape the deliverable. This is an illustrative workflow, not work completed for a client.
Sample output
Year 8 · Solve the equation
A ribbon is 20 cm long.
Set aside 5 cm. Cut the rest into 3 equal pieces. How long is each piece?
3x + 5 = 20
- 1
Subtract 5 from both sides
3x = 15 - 2
Divide both sides by 3
x = 5 cm
Check: 3 × 5 + 5 = 20 cm.
Quick check: which inverse operation removes the +5? The sample is not yet reviewed by the founder or used with pupils.
Try the same structure
- 4x + 3 = 19
- 2x + 7 = 21
Show the teacher answers and checks
4x + 3 = 19 gives x = 4; check: 4 × 4 + 3 = 19. 2x + 7 = 21 gives x = 7; check: 2 × 7 + 7 = 21.
Human review
A reviewer would check the mathematics for accuracy, make sure the reasoning is visible at each step, and test the wording for clarity. They would also consider fit for Year 8 learners and the intended classroom context, then compare the result with the brief.
Relevant review context: the founder has a maths degree from Loughborough University, a PGCE from Leicester University, and currently works as a Maths teacher in a secondary school. These facts describe the founder’s background; they are not evidence that this sample has been reviewed. Founder review is pending.
This illustrative, synthetic sample does not describe a real client, engagement or customer outcome. It has not been used with pupils, and no learner feedback or achieved learning result is claimed. The topic and context are proposed examples, not a report of the founder’s current class or teaching plan.
The founder can inspect and adapt the sample with the learning-resource review checklist before any pilot use.
