Explain the relationship between investment in human capital, productivity, and future incomes.
Objective
Students will be able to trace a chain from training through output to income, and name its cost.
Students are successful when they can
- Names what the training lets somebody do.
- Links that to what they can earn.
- Names the cost of getting the training.
What you need
- The board minute on half-time working
- Chain cards: training, output, earnings
- The printable practice sheet linked at the end of this plan
The lesson
Warm-up — the wage they lost
5 min- Read the dissenting members' reason: families depend on the wage.
- Ask what the board was asking those families to give up, and for what.
Teach — three links, and a price
17 min- Build the chain: a child stays at school, can take clerk's work, is paid more than a half-timer.
- Say the middle link plainly: schooling pays because it changes what she can produce.
- Name the cost: the wage the family loses now, for a gain years later.
- Ask why a poor family might rationally refuse that trade. They cannot wait years.
- Do a second chain: a spinner learns four frames, produces more, earns a higher rate.
- Do a broken chain: a weaver's skill in a failing trade earns nothing at all.
- Say the general rule: training pays when a market for it still exists.
“What can they now do that they could not do before, and who paid for the waiting?”
Guided practice — build and price
15 min- Pairs build four chains from cards.
- For each they write the cost of getting the training.
- Groups find one chain that broke, and say when.
Independent practice
10 min- Students complete the 'What Training Changes' page.
- Check the middle link is present.
Close
3 min- Ask what the class is learning now that has a middle link.
What goes wrong, and why
Each of these is a reasoning error rather than carelessness. The fix addresses the reasoning.
Jumps from training straight to money.
Why: It is the slogan people repeat.
Fix: Insert the middle link. Training pays because of what it lets you produce.
Thinks the training is free because school is.
Why: No fee is charged.
Fix: The family loses the child's wage. That is the price, and it fell on the poorest.
Assumes any training pays.
Why: The chain looks automatic.
Fix: A weaver's skill in 1885 earned nothing. Ask whether the market still exists.
If they are not there yet
- Two chains with the middle link supplied.
- Match a training card to an earnings card.
If they finish early
- Build a chain for a skill that stopped paying, and say when it broke.
- Explain why a board would pay for schooling from rates.
- Compare two trainings by how long they take to repay.
Exit ticket
A child stays at school to eleven instead of working half-time. Name the middle link and the cost.
What to look for: She can do work needing reading and writing, at the cost of the wage the family loses meanwhile. Skipping to pay means the middle link needs another run.

Questions about What Training Changes
How long does the What Training Changes lesson take?
50 minutes, split across 5 timed sections: warm-up 5 min, teach 17 min, guided practice 15 min, independent practice 10 min, close 3 min. The minutes are stated per section and add up to the stated length, so the plan can be cut or extended at a section boundary rather than abandoned halfway.
Which standard does What Training Changes teach?
D2.Eco.6.3-5 — D2.Eco.6.3-5, Economics for Grade 3 to Grade 5: “Explain the relationship between investment in human capital, productivity, and future incomes.” In plain terms, explain how training and education change what somebody can earn.
What do I need to teach this lesson?
The board minute on half-time working, chain cards: training, output, earnings and the printable practice sheet linked at the end of this plan. Everything listed is either ordinary classroom equipment or a free printable from this site — there is nothing to buy and nothing to prepare beyond photocopying.
What mistakes should I expect in this lesson?
Three, each a reasoning error rather than carelessness: jumps from training straight to money; thinks the training is free because school is and assumes any training pays. The plan gives the thinking behind each one and the teaching move that addresses the thinking rather than the symptom.
How do I know whether the lesson worked?
The exit ticket asks: “A child stays at school to eleven instead of working half-time. Name the middle link and the cost.” She can do work needing reading and writing, at the cost of the wage the family loses meanwhile. Skipping to pay means the middle link needs another run. That tells you whether the class needs a reteach or a thirty-second conversation before you plan tomorrow.
Is there a worksheet to go with What Training Changes?
Yes — 1 printable D2.Eco.6.3-5 worksheet, linked at the end of the plan and free like the rest of the site. Each one comes with an answer key and 25 versions, so the practice after the lesson can be a different paper on every desk.

Yes. The plan, its printables and their answer keys are free to read, print and photocopy for your own class, with no account and no email capture. It was last reviewed on 7 September 2026. Please do not resell it or republish it as your own.
