Welcome to the bustling Fraction & Money Market! 👋

I'm Miko the Market Ninja, and I help shoppers, bakers, and stall owners use maths every day.

Today you will learn two very useful skills:

🍕 Fractions to describe parts of a whole

💵 Money change to shop like a clever customer

We will use number lines, pizza slices, coins, and shop problems to train your brain.

Ready to share fairly and spend wisely? Let's go! ✨

A fraction shows part of a whole.

A unit fraction has 1 on the top: 1/2, 1/4, 1/8.

The bottom number tells how many equal parts the whole is split into.

So:

🍰 1/2 means 1 out of 2 equal parts

🍫 1/4 means 1 out of 4 equal parts

🍕 1/8 means 1 out of 8 equal parts

If the parts are not equal, it is not a correct fraction picture.

A number line helps us see where fractions belong between 0 and 1.

1/2 sits right in the middle.

1/4 is smaller, so it sits halfway between 0 and 1/2.

1/8 is even smaller, so it sits closer to 0.

From smallest to largest, the order is:

1/8, 1/4, 1/2

On a number line, bigger fractions are farther to the right.

Before we calculate change, let's remember Australian money values.

Coins: 5c, 10c, 20c, 50c, $1, $2

Notes: $5, $10, $20, $50, $100

Money amounts always use dollars and cents.

For example:

$3.50 means 3 dollars and 50 cents.

$7.05 means 7 dollars and 5 cents.

Always write cents with two digits.

Change is the money you get back after paying.

Change = amount paid - cost

Example: A toy costs $4.75. You pay with $5.00.

Count up:

4.75 → 5.00 is 25c

So the change is $0.25.

Another example: A book costs $6.40. You pay with $10.00.

10.00 - 6.40 = $3.60.

A fruit tart is cut into 8 equal slices.

If you take 1 slice, that is 1/8.

On a number line from 0 to 1, 1/8 sits closest to 0.

If another tart is cut into 4 equal slices, 1 slice is 1/4.

Because 1/4 is bigger than 1/8, it sits farther to the right.

And 1/2 is bigger still, because half of something is a large piece.
