Step inside! Mr. Fraction will guide you through everything — from what fractions are, to simplifying, operating, and converting them. Pick a station below to get started.
STATION 01
Discover what fractions are, why they matter, and how to read them. Interactive activities included!
STATION 02
Find the Greatest Common Factor and shrink fractions down to their simplest form, step by step.
STATION 03
Add, subtract, multiply, and divide fractions with visual rectangle models showing exactly what's happening.
STATION 04
See how fractions, decimals, and percentages all describe the same amount — just in different ways.
Work through each step — click, explore, and answer questions as you go.
A fraction tells us about a part of something whole.
Imagine you have a pizza cut into 4 equal slices. If you eat 1 slice, you've eaten one-quarter of the pizza. We write that as a fraction: 1/4.
Click on the pizza below to eat slices and see the fraction change!
Every fraction has two parts. Let's use 3/4 as an example.
The number on top is the Numerator — it tells you how many parts you have.
The number on the bottom is the Denominator — it tells you how many equal parts the whole is cut into.
In the fraction 5/8 — what does the 8 tell us?
The Factory produces three types of fractions. Click each one to learn more!
Which of these is an improper fraction?
Some fractions look different but are worth the same! We call these equivalent fractions.
Look at the pattern below. Can you spot what's happening? Use the sliders to explore!
| Multiply by | Numerator (×) | Denominator (×) | Equivalent Fraction |
|---|
Which fraction is equivalent to 2/3?
Which is bigger — 1/2 or 1/3?
When the numerator is the same, the fraction with the bigger denominator is actually smaller — because you're cutting into more pieces!
Use the builder below to compare two fractions visually.
Fractions live on the number line between whole numbers! Drag the slider to place a fraction and watch where it lands.
Fractions are everywhere! Match each real-life situation to the correct fraction.
Amazing work! You've learned the basics of fractions. Here's what you now know:
