What Does Class 4 Maths Cover?

Class 4 marks a transition from early primary to upper primary maths. The numbers grow to five digits, multiplication becomes 2-digit by 2-digit, and children encounter entirely new concepts like factors and multiples, decimals, angles, and perimeter and area.

The CBSE Class 4 maths syllabus has 12 chapters that demand more reasoning and less counting on fingers. Word problems become multi-step, and children are expected to choose the right operation themselves rather than being told whether to add or subtract.

Here is a chapter-by-chapter overview.

Large Numbers and Arithmetic

Numbers up to 99,999 — The Indian place value system is introduced formally. Children learn about ten-thousands and work with the Th, H, T, O columns. Roman numerals up to 50 are also covered.

Addition & Subtraction of Large Numbers — Operations with five-digit numbers and estimation. Children learn to round numbers and estimate answers before computing — a critical real-world skill.

Multiplication (2-digit) — Multiplying up to a 3-digit number by a 2-digit number using the standard algorithm. For example, 234×26234 \times 26. Word problems involve rate, quantity, and price.

Long Division — Dividing up to a 4-digit number by a 1-digit number. Children learn the formal long division algorithm and understand what quotient and remainder mean.

Example: 2537÷6=4222537 \div 6 = 422 remainder 55

Factors, Multiples & Prime Numbers

This chapter is new in Class 4 and introduces important number theory concepts that will stay relevant through Class 10.

What your child will learn:
- Factors of a number: all numbers that divide it exactly. Factors of 12 are 1, 2, 3, 4, 6, 12.
- Multiples of a number: the times table of that number. Multiples of 4 are 4, 8, 12, 16, ...
- Prime numbers: numbers with exactly two factors (1 and themselves). Examples: 2, 3, 5, 7, 11, 13.
- Composite numbers: numbers with more than two factors.
- HCF and LCM basics: finding common factors and common multiples of small numbers.

This chapter lays the groundwork for fractions (finding common denominators), algebra, and divisibility rules in higher classes.

Fractions and Decimals

Fractions — A significant step up from Class 3. Children now work with like fractions (same denominator), compare them, and perform addition and subtraction of like fractions.

Example: 37+27=57\frac{3}{7} + \frac{2}{7} = \frac{5}{7}

They also learn to convert between mixed numbers and improper fractions: 213=732\frac{1}{3} = \frac{7}{3}.

Decimals — Introduced through the context of money (Rs 25.50) and measurement (1.5 metres). Children learn tenths and hundredths, read decimal numbers on a number line, and compare decimals.

The connection between fractions and decimals (12=0.5\frac{1}{2} = 0.5, 14=0.25\frac{1}{4} = 0.25) is introduced gently.

Both topics require careful teaching. Use visual models — fraction strips, number lines, and base-ten blocks — to make abstract notation concrete.

Measurement, Time & Geometry

Measurement (Length, Weight, Capacity) — Children consolidate unit conversions (km-m-cm, kg-g, L-mL) and solve multi-step word problems involving measurement.

Time — The 24-hour clock is introduced. Children calculate durations, read timetables, and solve problems involving start time, end time, and elapsed time.

Geometry (Angles & Shapes) — A major new topic. Children learn what an angle is, identify right angles, acute angles, and obtuse angles, and classify shapes based on their angles. They are introduced to quadrilaterals (rectangle, square, rhombus, parallelogram) and basic properties of circles (centre, radius).

Perimeter & Area — Children calculate the perimeter of rectangles, squares, and irregular shapes by adding side lengths. Area is introduced through counting unit squares on a grid. The formulas for area and perimeter of rectangles are taught.

Perimeter of rectangle=2×(l+b)\text{Perimeter of rectangle} = 2 \times (l + b)

Area of rectangle=l×b\text{Area of rectangle} = l \times b

Data Handling

The final chapter covers bar graphs — reading them, drawing them, and interpreting data. Children learn to organise raw data into tables, choose appropriate scales, and draw bar graphs on grid paper.

They answer analytical questions such as "How many more students prefer cricket than football?" and "Which two activities together have the same number of students as the most popular one?"

Data handling teaches children to think critically about information — a skill that extends well beyond maths.

Tips for Parents of Class 4 Children

1. Help your child master long division. Break the algorithm into steps: Divide, Multiply, Subtract, Bring down. Use simple problems first and gradually increase difficulty. Patience is key — this method takes time to learn.

2. Build a factor-multiple vocabulary. At dinner, pick a number and ask everyone to name its factors. Play "Buzz" — count in turns and say "buzz" for multiples of a chosen number.

3. Use graph paper for geometry and area. Drawing shapes on graph paper makes angles and areas tangible. Let your child measure angles with a protractor for the first time.

4. Connect decimals to money. Rs 10.75 is a decimal. Let your child read receipts, total up prices, and verify change using decimal addition.

5. Encourage multi-step problem solving. Class 4 word problems often need two operations. Teach your child to underline key information, decide what to find, and plan the steps before computing.

6. Review earlier concepts regularly. Multiplication tables, place value, and basic fractions from earlier classes should remain sharp. A 5-minute warm-up drill each day keeps these skills fresh.
