Fractions for kids, explained simply
A fraction is a way to describe part of a whole. If you cut a pizza into 4 equal slices and take 1, you have 1/4. The bottom number (the denominator) tells you how many equal parts the whole is split into; the top number (the numerator) tells you how many of those parts you have.

The big ideas
Top and bottom have jobs
In 3/4, the bottom number (4) says “split the whole into 4 equal parts.” The top number (3) says “take 3 of them.” Equal parts is the key word.
Different fractions, same amount
1/2 and 2/4 look different but are exactly the same amount — half. These are called equivalent fractions, and spotting them is a real superpower in maths.
Fractions are everywhere
Half an hour, a quarter of a cake, three-quarters of the way there. Fractions aren’t just on worksheets — they’re how we share and measure every day.
A quick quiz
1. In the fraction 1/4, what does the 4 tell you?
Choices: How many parts you take · How many equal parts the whole is split into · To add four
Answer: How many equal parts the whole is split into. The bottom number (denominator) tells you how many equal parts the whole is divided into. The top number tells you how many you take.
2. Which of these is the same amount as 1/2?
Choices: 2/4 · 1/3 · 3/4
Answer: 2/4. 2/4 is the same as 1/2 — both mean “half.” Fractions that name the same amount are called equivalent fractions.
3. You eat 3 of 4 equal slices of pizza. What fraction did you eat?
Choices: 1/4 · 3/4 · 4/3
Answer: 3/4. You took 3 out of 4 equal parts, so that’s 3/4 — three-quarters of the pizza.
For parents: helping your child think about fractions
Fractions are where a lot of children first decide “I’m not a maths person” — usually because the symbols arrive before the meaning. Keep it physical and real for as long as you can. Food is your best friend: cut a sandwich into equal parts and let them serve the family fairly. The word “equal” is doing the heavy lifting — three uneven pieces are not thirds. Once the idea of equal parts is solid, equivalent fractions stop being a trick: fold a paper strip in half (1/2), fold it again (2/4), and they can *see* it’s the same length. That moment of “oh, they’re the same!” is real understanding, not memorising a rule. Connect it to time and money, which they already use: half an hour, a quarter. The thinking skill underneath is “part–whole relationships,” and it underpins decimals, percentages, and probability later on. Keep it calm and curious — there’s no score here, so a mistake is just a chance to look again. Then ask them to explain why 2/4 equals 1/2 in their own words.
Frequently asked questions
What is a fraction in simple terms?
A fraction is part of a whole. If you split something into equal parts, a fraction tells you how many of those parts you have — like 1 out of 4 equal slices, written 1/4.
What do the top and bottom numbers mean?
The bottom number (denominator) is how many equal parts the whole is divided into. The top number (numerator) is how many of those parts you’re talking about.
What are equivalent fractions?
They’re fractions that name the same amount, like 1/2 and 2/4. They look different but are worth exactly the same — a key idea for working with fractions later.
