3rd Grade — Money & Business

Budgets that hold, comparison shopping, and how ads work on you.

Ages 8–9

The one idea

A budget is a plan you make before the money arrives — and adverts are designed to break it.

Lesson 1 of 6

💼 Earn

Getting paid for skill, not time

You can get paid for an hour of your time, or you can get paid for something you're good at. The second one pays better, because the person buying can't easily do it themselves.

Elif gets faster. Watch what happens to her pay.

Charging $4 an hour

$2.67

A 40-minute walk earns two thirds of an hour's pay. Getting better made her poorer.

✓ Better deal

Charging $4 a walk

$4.00

Same walk, same dog, same neighbour — and now speed is worth something.

She did not raise her price. She changed what she was selling from her time to her result.

Lesson 1 of 6 · A story

The dog walker who stopped charging by the hour

Elif walked her neighbour's dog for $4 an hour. After a few months she was quick at it, and being quick meant earning less — a job that used to take an hour took forty minutes. So she started charging $4 a walk instead of $4 an hour. The neighbour did not mind at all, because what she was buying was a walked dog, not sixty minutes of Elif.

What was the neighbour actually paying for?

The result. Almost nobody buys your time — they buy the thing at the end of it. Charge for the walk and getting faster makes you richer instead of poorer.

Lesson 1 of 6 · Try it

The usual mistake

Charging by the hour for anything you are getting better at. It quietly punishes every improvement you make.

The fix

Price the job, not the clock. "$4 a walk" and "$4 an hour" sound the same and behave completely differently.

Do this

Name one thing they're better at than most kids their age. Work out who would pay for that and what it would be worth.

Say this

"What can you do that other people find hard? That's the thing worth charging for."

Lesson 2 of 6 · A story

The tin you're allowed to open and the one you're not

Jonah kept everything in one tin, and every time something went wrong — a broken kite, a friend's birthday he'd forgotten — the tin got emptied and his bike fund went back to zero for the fourth time. His mum gave him a second tin. One was for surprises. One was for the bike. He got the bike in five months.

Why did two tins work when one didn't?

Because a single pot has to do two opposite jobs: be available for emergencies and be untouchable for goals. It cannot do both, so it does the first one and the goal never arrives.

Lesson 2 of 6 · Try it

The usual mistake

One savings pot. The goal money always gets eaten by the surprises, and the child concludes they are bad at saving.

The fix

Two containers, two names, two rules. The surprise tin is allowed to be opened. That is the only reason the other one survives.

Do this

Split their saving into two labelled envelopes: GOAL and JUST IN CASE. Fund both, even unevenly.

Say this

"What happens if something breaks and all your money is locked into the bike goal?"

Lesson 3 of 6 · A story

Watching the advert instead of watching the show

Sadia's teacher played three adverts and then, instead of asking what the products were, asked what each advert had promised. The chocolate bar had promised friends. The trainers had promised being fast. The phone had promised not being left out. None of the three adverts had said anything about what the thing actually did.

Why sell a feeling instead of the product?

Because a chocolate bar is 40¢ of ingredients and being liked is priceless. The feeling is what carries the price.

Lesson 3 of 6 · Try it

The usual mistake

Telling children adverts lie. Mostly they don't — they are careful and true and still work on you completely.

The fix

Play the game instead: name the feeling being sold within ten seconds. Once you can see the machinery you cannot unsee it.

Do this

Watch three adverts. For each, write down what feeling they're selling and what the product actually does.

Say this

"What are they showing you? Now — what does the product actually do? Are those the same thing?"

Lesson 4 of 6

💝 Give

Giving time is giving

An hour of real help is often worth more than the money you could have earned in that hour. Charities need hands as much as they need cash, and you have hands right now.

Ben gave twice. Here is what each gift did.

$20 from the class

1 bag of compost

Useful, and gone in a week.

✓ Better deal

Two Saturdays of weeding

1 cleared bed

Three years overgrown. Now grows potatoes.

Give what the cause is short of. Sometimes that is money and very often it is not.

Lesson 4 of 6 · A story

Two hours worth more than $20

Ben's class raised $20 for the community garden. Ben also spent two Saturdays there pulling weeds. At the end of the year the garden's organiser said the money had bought a bag of compost, and Ben's two Saturdays had cleared a bed that had been overgrown for three years and now grew potatoes.

Which one helped more?

The Saturdays — because nobody had $200 to pay someone to do them. Time is worth most exactly where money is shortest.

Lesson 4 of 6 · Try it

The usual mistake

Treating giving as only ever a money question. It quietly teaches that people without money have nothing to give.

The fix

Ask what the cause is short of. Sometimes it is cash. Very often it is hands, or hours, or someone who will show up twice.

Do this

Do one hour of genuine volunteering. Afterwards, work out what that hour would have been worth in money.

Say this

"You just gave an hour. If someone had paid for that hour, what would it have cost them?"

Lesson 5 of 6

📈 Grow

The bank pays you to wait

When your money sits in a savings account, the bank uses it and pays you a little for the privilege. That payment is called interest. It's small — but it arrives without you doing anything.

$100, left alone at 5%, doing nothing at all.

Start$100
After 1 year$105
The bank added $5
After 5 years$128
$28 — more than 5 lots of $5
After 10 years$163
$63, and Amara never added a cent

Ten years of $5 would be $50. She got $63, because the interest started earning interest of its own.

Lesson 5 of 6 · A story

$100 that grew while Amara was asleep

Amara put $100 in a savings account paying 5% and left it completely alone. She did not add a cent. At the end of the first year the bank had put in $5. At the end of the second year it put in $5.25, because by then it was paying interest on $105. Amara's dad pointed at the extra 25¢ and said, "That is the most important 25 cents you will ever see."

Why did the second year pay more than the first, when Amara did nothing?

Because the interest earned interest. The pile that is growing is bigger than it was, so the growth is bigger too. That is compounding, and 25¢ is what it looks like at the start.

Lesson 5 of 6 · Try it

The usual mistake

Showing compounding over one or two years. It looks like almost nothing, which is exactly the wrong conclusion.

The fix

Show ten years next to one. The first year is the least impressive year it will ever have — that is the point.

Do this

Work out 2% of their savings total. Then work out what it would be after five years of leaving it alone.

Say this

"You did nothing and the money grew. Small — but it grew while you were asleep."

Lesson 6 of 6

🧠 Mindset

Opportunity cost

Every yes is a no to something else. Spending $20 on a game isn't just $20 — it's also the thing you didn't buy with that $20. Good decisions come from asking what you're giving up.

Ada has $9. Both of these cost $9.

The card game

Hers today. And she turns up to the party empty-handed.

✓ Better deal

A present in two weeks

Not hers, and worth more to her than the game.

The price of anything is the money plus the next best thing that money could have done.

Lesson 6 of 6 · A story

The $9 that was really a decision about a party

Ada had $9 and wanted a card game that cost exactly $9. Her friend's birthday was in two weeks and a present would cost about the same. Her dad didn't tell her what to do; he just made her say out loud what buying the game would mean. "It means I turn up with nothing," she said, and put the game back without being asked.

What did the game really cost?

Nine dollars and the present. Everything you buy costs the money and the next best thing that money could have done — and the second half is the half nobody counts.

Lesson 6 of 6 · Try it

The usual mistake

Asking "can I afford this?" It is the easy question and the answer is usually yes.

The fix

Ask "what does this stop me buying?" instead. Naming the thing you are giving up out loud is what makes the choice real.

Do this

Before their next purchase over $10, write down the other thing that same money could have bought.

Say this

"If you buy this, what are you not buying? Write it down before you decide."

The Four Jars

Move the sliders and watch what each jar becomes. Only the Grow jar is invested, so only Grow compounds — that is the whole reason the numbers separate.

Money in each week

Save30% · $1.50/week

$78 a year → $780 after 10 years

Look ahead:

$2,600

You end up with

$2,911

Grew on its own

+$311

That extra $311 is money nobody worked for. It came from the Grow jar earning 7% a year on a balance that keeps getting bigger.

For parents: About $5 a week. Big enough that trade-offs are real, small enough that mistakes stay cheap.

The 7% is a rough long-run stock market average used for illustration. Real returns vary, some years are negative, and nothing here is investment advice.

📖 The words they need this year

Interest: Money the bank pays you for leaving your money with them.; Like: $100 at 2% earns $2 in a year, without you lifting a finger.
Emergency fund: Money set aside for when something goes wrong.; Like: The envelope you don't touch for the bike.
Opportunity cost: The thing you gave up to get what you chose.; Like: Buying the game means not buying the skateboard.
Advertisement: A message designed to make you want to buy something.; Like: The clip before the video, selling you a feeling.
Account: A place a bank keeps your money for you.; Like: Your savings account at the bank.
Compare: Look at two options side by side before deciding.; Like: Checking three shops before buying the trainers.

📜 This actually happened

Some countries made it illegal to advertise to you

In Quebec, advertising aimed at children under thirteen has been banned since 1980. Sweden banned television advertising aimed at under-twelves in 1991, and Norway did the same. The argument was not that the adverts lied. It was that children cannot yet see that an advert is trying to persuade them — so the adverts were working perfectly, and that was the problem.

Whole countries decided adverts were too effective on children to be allowed. That is worth knowing next time one works on you.

This week's mission

The Advert Decoder

They learn to separate what an advert shows from what the product does — and it doesn't wear off.

⏱️ 30 minutesThree adverts (TV, YouTube, or magazine)Paper split into three columns

1Head the columns: WHAT THEY SHOW / WHAT IT ACTUALLY DOES / WHO IT'S AIMED AT.
2Watch each advert twice — once normally, once with the sound off.
3Fill in all three columns for each one.
4Circle the advert that worked best on you, and work out why.
5Write one sentence: what would this advert look like if it could only state facts?

🚀 Starter business

The Skill Service

"I'm good at this one thing, and I'll do it for you for a fixed price."

What it costs to start

$0–10 depending on the skill

What to charge

Charge per job, not per hour. Fixed prices are easier to sell and they reward you for getting faster.

1Pick the one thing they're genuinely better at than most kids their age.
2Find three people who'd want that done and can actually pay.
3Set one fixed price per job and write it on a small flyer.
4Do the first job brilliantly, even if it takes twice as long as planned.
5Ask that first customer for one referral. Referrals are cheaper than any advertising.

The business lesson underneath

Fixed pricing. Getting faster raises your effective hourly rate — hourly pricing punishes you for the same improvement.

3rd Grade — Money & Business

Budgets that hold, comparison shopping, and how ads work on you.

Full screen — no distractions

For grown-ups: 3rd Grade money

Eight and nine year olds can run a monthly budget and can genuinely learn to spot advertising techniques. This is the year the marketing lesson lands hardest.

Four questions to ask this week

No printing, no materials, no lesson. Ask one at dinner and let the answer go wherever it goes — most of what children learn about money they overhear.

1"What feeling is that advert selling?" Play it for ten seconds and pause before the product appears.
2"What does buying this stop us buying?" Ask it about something real you are deciding on this week.
3"Would you rather be paid for the hour or for the job?" Ask about a chore, and follow the reasoning.
4"What is that charity short of — money, or people?" Then find out which by looking.

Three habits that matter at this age

The money lessons only stick if these are running underneath them.

Ask "compared to what?"

Applied to prices, claims, and adverts alike, this one question does more work than any other single money habit.

Run a monthly review

Fifteen minutes at the end of each month: what came in, what went out, what surprised you. Reviewing is what turns tracking into learning.

Name the skill they're building

Say it explicitly: "You're getting good at pricing." Children invest in skills they know they have.

By the end of 3rd Grade

Tick these off through the year. If one is still open in June, that's the lesson to go back to.

Runs a written monthly budget and adjusts it when it breaks
Keeps separate goal and emergency savings
Identifies the technique an advert is using
Calculates simple interest on a savings balance
States the opportunity cost of a purchase before making it
Sets a fixed price for a service and explains the reasoning

Frequently Asked Questions

What should a 3rd Grade child understand about money?

A budget is a plan you make before the money arrives — and adverts are designed to break it. Concretely: runs a written monthly budget and adjusts it when it breaks; keeps separate goal and emergency savings; identifies the technique an advert is using. The six lessons on this page cover each of those, and the money check tells you which ones have landed.

How much allowance should a 3rd Grade child get?

Around $5 a week is a reasonable starting point at ages 8–9. About $5 a week. Big enough that trade-offs are real, small enough that mistakes stay cheap. The calculator on this page lets you try different amounts and splits.

What business can a 3rd Grade child actually run?

The Skill Service: "I'm good at this one thing, and I'll do it for you for a fixed price." Startup cost is $0–10 depending on the skill. Fixed pricing. Getting faster raises your effective hourly rate — hourly pricing punishes you for the same improvement.

What is the most common money mistake 3rd Grade children make?

Charging by the hour for anything you are getting better at. It quietly punishes every improvement you make. Price the job, not the clock. "$4 a walk" and "$4 an hour" sound the same and behave completely differently. Each of the six lessons on this page names the trap for its own pillar and the smallest change that fixes it.

Is the 3rd Grade money content on this page free?

Yes — all 6 lessons and their pictures, the 8-question check, the 6 stories, the 3 decision cards, the 4 worked money sums, the questions to ask at dinner, the vocabulary, the mission, the starter business, the allowance calculator, and the milestones are free with no signup. The 3rd Grade printable packs in the shop are optional.

Does this work for a child who cannot read yet?

Every lesson on this page has a picture as well as words, so a younger sibling can follow along. If your child is not reading independently yet, start at the Pre-K or Kindergarten page instead — those are built to be spoken and pointed at.
