Fractions Worksheet for Class 3 ICSE — Free PDF with Answers

Fractions are one of the most important mathematical concepts introduced in primary school. In Class 3, the ICSE syllabus moves beyond the informal "half a roti" understanding that children have from daily life and begins building a structured, mathematical framework for parts of a whole.

The ICSE board, governed by CISCE, introduces fractions visually in Class 3 — through shaded shapes, divided strips, and collections of objects. Children learn to name fractions, compare unit fractions, recognise equivalent fractions, and perform simple addition of like fractions. This visual, conceptual approach sets up the more formal fraction arithmetic that follows in Classes 4 and 5.

Many parents worry about fractions because they remember struggling with them. The good news is that with the right worksheets and practice, Class 3 fractions are quite manageable. This Class 3 ICSE fractions worksheet provides 60 questions across three levels, each with detailed visual and numerical solutions.

The ICSE Class 3 fractions unit covers the following core ideas.

Parts of a whole. A fraction represents equal parts of a whole. If a circle is divided into 4 equal parts and 3 are shaded, the shaded portion is $\frac{3}{4}$.

Numerator and denominator. The top number (numerator) tells how many parts are taken. The bottom number (denominator) tells how many equal parts the whole is divided into.

Unit fractions. Fractions with numerator 1: $\frac{1}{2}$, $\frac{1}{3}$, $\frac{1}{4}$, $\frac{1}{5}$, etc. These are the building blocks of all fractions.

Fraction of a collection. $\frac{1}{4}$ of 20 buttons means dividing 20 buttons into 4 equal groups — each group has 5 buttons.

Equivalent fractions. $\frac{1}{2} = \frac{2}{4} = \frac{3}{6}$. Different fractions that represent the same portion.

Comparing unit fractions. Among unit fractions, the one with the smaller denominator is larger: $\frac{1}{3} > \frac{1}{5}$ because thirds are bigger pieces than fifths.

Comparing like fractions. Fractions with the same denominator: $\frac{5}{8} > \frac{3}{8}$ because 5 parts out of 8 is more than 3 parts out of 8.

Simple addition and subtraction of like fractions. $\frac{2}{7} + \frac{3}{7} = \frac{5}{7}$. When denominators are the same, just add the numerators.

The worksheet uses varied formats, many with a visual component.

• Identify the fraction — A shape is divided into equal parts with some shaded. Write the fraction.
  - Shade the fraction — Shade $\frac{3}{5}$ of a given rectangle divided into 5 equal parts.
  - Fraction of a collection — Find $\frac{1}{3}$ of 18.
  - Write the numerator and denominator — In $\frac{4}{9}$, the numerator is ___ and the denominator is ___.
  - Equivalent fractions — Fill in: $\frac{1}{2} = \frac{?}{6}$.
  - Compare fractions — Use $>$, $<$ or $=$: $\frac{1}{4}$ ___ $\frac{1}{6}$.
  - Add like fractions — $\frac{2}{5} + \frac{1}{5} =$ ___.
  - Subtract like fractions — $\frac{5}{8} - \frac{2}{8} =$ ___.
  - Word problems — Ria ate $\frac{2}{6}$ of a pizza and her brother ate $\frac{3}{6}$. What fraction was eaten in total?
  - True or false — $\frac{1}{3}$ is greater than $\frac{1}{2}$. True or false?

The visual questions are essential at this level — they connect the abstract notation to something children can see and touch.

Level 1 focuses on reading fractions from pictures, naming parts, and basic vocabulary.

Sample questions:

1. A rectangle is divided into 6 equal parts. 4 parts are shaded. What fraction is shaded?
*Answer: $\frac{4}{6}$*

2. What is the numerator in $\frac{3}{7}$?
Answer: 3

3. Write a fraction for: five out of eight equal parts.
*Answer: $\frac{5}{8}$*

4. Find $\frac{1}{2}$ of 16.
*Answer: $16 \div 2 = 8$*

5. Is $\frac{3}{3}$ equal to a whole? Why?
*Answer: Yes. If a whole is divided into 3 equal parts and all 3 are taken, that is the entire whole. $\frac{3}{3} = 1$.*

Level 1 builds the vocabulary and visual understanding that all later fraction work depends on. Children should be able to look at any divided shape and instantly write the fraction represented by the shaded portion.

A useful home activity: cut a roti or sandwich into equal pieces and ask your child to name the fraction of each piece and the fraction eaten.

Level 2 introduces the idea that different fractions can represent the same amount, and teaches comparison of fractions.

Sample questions:

1. Fill in the blank: $\frac{1}{3} = \frac{?}{9}$.
*Answer: $\frac{3}{9}$. Since $1 \times 3 = 3$ and $3 \times 3 = 9$, the missing numerator is 3.*

2. Are $\frac{2}{4}$ and $\frac{1}{2}$ equivalent? Explain.
*Answer: Yes. If you simplify $\frac{2}{4}$ by dividing numerator and denominator by 2, you get $\frac{1}{2}$.*

3. Compare using $>$, $<$ or $=$: $\frac{1}{5}$ ___ $\frac{1}{3}$.
*Answer: $\frac{1}{5} < \frac{1}{3}$. Among unit fractions, the larger denominator means smaller pieces.*

4. Find $\frac{3}{4}$ of 24.
*Answer: First find $\frac{1}{4}$ of 24 = 6. Then $\frac{3}{4}$ of 24 = $3 \times 6 = 18$.*

5. Compare: $\frac{5}{9}$ ___ $\frac{7}{9}$.
*Answer: $\frac{5}{9} < \frac{7}{9}$. Same denominator, so compare numerators: $5 < 7$.*

Level 2 is where the conceptual understanding of fractions deepens. Children learn that a fraction is not just a pair of numbers but a single value on the number line, and that different pairs can represent the same value.

Level 3 introduces addition and subtraction of like fractions and applies fractions to real-life situations.

Sample questions:

1. Add: $\frac{3}{8} + \frac{4}{8}$.
*Answer: $\frac{3 + 4}{8} = \frac{7}{8}$.*

2. Subtract: $\frac{5}{6} - \frac{2}{6}$.
*Answer: $\frac{5 - 2}{6} = \frac{3}{6} = \frac{1}{2}$.*

3. Ananya read $\frac{3}{10}$ of a book on Monday and $\frac{4}{10}$ on Tuesday. What fraction has she read so far?
*Answer: $\frac{3}{10} + \frac{4}{10} = \frac{7}{10}$. She has read $\frac{7}{10}$ of the book.*

4. A jug is $\frac{5}{8}$ full of water. After pouring out some water, it is $\frac{2}{8}$ full. What fraction of water was poured out?
*Answer: $\frac{5}{8} - \frac{2}{8} = \frac{3}{8}$.*

5. Arrange in ascending order: $\frac{1}{2}$, $\frac{1}{5}$, $\frac{1}{3}$, $\frac{1}{8}$.
*Answer: $\frac{1}{8} < \frac{1}{5} < \frac{1}{3} < \frac{1}{2}$. For unit fractions, larger denominators mean smaller values.*

Level 3 questions are typical of what ICSE annual examinations expect. The word problems test whether children can identify the correct operation (add or subtract) and apply it to fractions, not just whole numbers.

Use food. Cut an apple into 4 equal pieces. Your child has eaten 1 piece — what fraction is left? This makes fractions tangible and delicious.

Paper folding. Give your child a rectangular piece of paper. Ask them to fold it in half, then unfold and shade one half. Now fold it into quarters and shade one quarter. Compare the sizes. This visual exploration builds deep understanding.

Fraction strips. Cut paper strips of the same length. Leave one whole, cut another into halves, another into thirds, another into quarters. Line them up to compare: children can see that $\frac{1}{2} > \frac{1}{3} > \frac{1}{4}$.

Connect fractions to division. "What is $\frac{1}{4}$ of 20?" is the same as "What is 20 divided by 4?" Making this connection explicit helps children who are already confident with division.

Avoid rushing to unlike fractions. The ICSE Class 3 syllabus wisely stays with like fractions for addition and subtraction. Do not push your child into unlike fraction operations at this stage — that comes in Class 4.

Praise visual reasoning. If your child draws a picture to solve a fraction problem, praise the strategy. Visual methods are mathematically valid and often more reliable than memorised rules at this age.
