The Hamilton Kids Guide to Money

What Is Money (And Why Does It Matter)?

Money is a tool.

It helps you buy things.
It helps you plan for the future.
It gives you choices.

But money is not the goal.

It’s what money allows you to do that matters.

You can use money to:

• Learn new skills

• Travel

• Start a business

• Help other people

• Feel secure

Understanding money early gives you more control later.

Spending, Saving and Growing

There are three main things you can do with money:

1. Spend it

This is for things you want or need now.

2. Save it

This is for things you’ll need soon — like a new bike or toy.

Saving keeps your money safe.

3. Grow it

This means investing it so it might become more over time.

A simple rule:

Spend some.
Save some.
Grow some.

Balance is powerful and important.

What Is Saving?

Saving means putting money somewhere safe so you can use it later.

Imagine you get £20.

You could spend it straight away.

Or you could put it aside for something bigger.

Saving helps you:

• Plan ahead

• Avoid running out of money

• Feel prepared

Savings don’t usually grow much — but they stay steady.

Saving is about safety.

What Is Investing?

Investing is different.

When you invest, you use your money to buy a small piece of something — usually a company.

If that company does well, your piece may become more valuable.

But investing is not perfectly smooth.

Sometimes values go up.
Sometimes they go down.

Investing is for money you don’t need anytime soon.

It’s about long-term growth.

What Is Compounding? (The Snowball Effect)

Compounding is when your money earns money…And then that money earns money too.

Imagine a snowball rolling downhill.

At first, it grows slowly.

But as it gets bigger, it picks up more snow each second.

The Sweet Jar Example

Imagine you put 10 sweets in a jar.

Each year, the jar magically adds 10% more sweets.

Year 1:
10 sweets becomes 11 sweets

Year 2:
Now you have 11 sweets
10% of 11 is 1.1
So now you have 12.1 sweets

Year 3:
10% of 12.1 is 1.21
Now you have 13.31 sweets

You’re earning sweets on your sweets.

That’s compounding.

Now think of it with Pocket Money

Let’s say you invest £100.

It grows by 5% per year.

After 1 year → £105
After 2 years → £110.25
After 3 years → £115.76

You’re not just earning 5% on £100 anymore.
You’re earning 5% on a bigger and bigger number.

Over time, this becomes powerful.

Time is the secret ingredient.

Why Starting Early Matters

Let’s imagine two people both age 18 who save for 10 years the only difference is when they start:

Alex

Alex invests £50 every month from age 18 to 28.

After 10 years Alex has invested:

£50 × 12 months × 10 years = £6,000

Then Alex stops investing, but leaves the money invested so it can keep growing.

Sam

Sam waits until age 28 to start investing.

Sam invests £100 every month from age 28 to 38.

After 10 years Sam has invested:

£100 × 12 months × 10 years = £12,000

Sam actually invests twice as much money as Alex.

What Happens Next?

If both investments grow at around 7% per year:

By age 60:

Alex’s money could grow to about £45,000

Sam’s money could grow to about £36,000

Even though Sam invested twice as much money, Alex ends up with more.

Why?

Because Alex’s money had 10 extra years to grow.

That extra time allowed compounding to work for longer.

Remember compounding means your money earns money…
and then that money earns money too.

Why Markets Go Up and Down

If you invest, you’ll notice something:

Prices move.

Sometimes they rise.
Sometimes they fall.

This is normal.

Companies grow.
Economies change.
News affects confidence.

Short-term drops don’t mean something is broken.

Long-term thinking matters more than short-term movement.

The Difference Between Investing and Gambling

Investing means owning real businesses that make real products.

Gambling means risking money on guessing short-term outcomes.

Investing focuses on:

Patience
Ownership
Long-term growth

Gambling focuses on:

Quick wins
Luck
Short-term outcomes

They are not the same.

The Tree Example

Think of investing like planting a tree.

At first, it looks small.
It grows slowly.

But after many years, it becomes strong and tall.

If you keep digging it up to check on it, it won’t grow properly.

Money works in a similar way.

It needs:

Time
Patience
Consistency

Diversification

Diversification means not putting everything in one place.

Ice Cream Example

Imagine bringing one flavour of ice cream to a party.

If people don’t like it, you’re stuck.

Now imagine bringing:

🍦 Chocolate
🍦 Vanilla
🍦 Strawberry

More people are likely to find a flavour they will enjoy.

That’s diversification.

Investing Example

Instead of investing in one company, investors often invest in many companies.

That way if one struggles, the others may still do well.

The Rule of 72

A quick way to guess how fast money can double

Sometimes investors want to know:

“How long will it take for my money to double?”

There is a simple trick called the Rule of 72.

It isn’t exact, but it gives a good estimate.

The Simple Rule

Take the number 72
Divide it by the growth rate

The answer tells you about how many years it will take for your money to double.

Example 1

Your investment grows at 10% per year

72 ÷ 10 = 7.2

Your money may double in about 7 years

So: £100 → about £200 in 7 years

Example 2

If your money grows at 6% per year

72 ÷ 6 = 12

Your money may double in about 12 years

So: £100 → about £200 in 12 years

Why This Matters

The Rule of 72 shows something important:

Small differences in growth can make a big difference over time.

Money growing at:

5% doubles in about 14 years

10% doubles in about 7 years

That’s twice as fast.

 Think of It Like This

Imagine planting two trees.

One grows slowly.
One grows faster.

After a few years they might look similar.

But after 20 or 30 years, the faster-growing tree can be much taller.

Money works the same way.

Smart Money Habits

You don’t need to be rich to be smart with money.

Good habits matter more than big amounts.

Strong habits include:

• Saving regularly

• Avoiding impulsive spending

• Thinking long-term

• Staying calm when markets wobble

Money rewards patience.

Money and Responsibility

Money gives you choices.

But it also brings responsibility.

It’s important to:

• Respect it

• Use it thoughtfully

• Understand where it comes from

• Appreciate the effort behind it

Money should support your life not control it. Print and complete our Junior Investor activity sheet here
