Class 5 maths: fractions and decimals finally click
Class 5 builds the base for middle school. Fractions get harder, decimals become everyday numbers, and word problems demand real thinking. It is also when many families first try Olympiad-style questions.

What children learn in Class 5 maths
Fractions
Adding and subtracting fractions with different denominators, mixed numbers and fractions of quantities.
Decimals
Place value to hundredths, adding, subtracting and comparing decimals.
Factors, multiples, divisibility
Divisibility tests, HCF and LCM in some books, and prime and composite numbers.
Multi-step word problems
Problems with two or three steps and the habit of checking if an answer is sensible.
Area, perimeter, volume
Rectangles and composite shapes, and an introduction to volume.
Patterns, data and averages
Number patterns, reading graphs and simple averages in some books.
CBSE, ICSE and state boards teach very similar ideas but in a different order and depth, and textbooks are revised from time to time. Tell us your board, your textbook and the topic your child is on, and we will start there instead of guessing.
Common trouble spots
Where Class 5 children usually get stuck
- Unlike denominators. Children add the tops and the bottoms. Show why with a picture, then teach finding a common denominator.
- Decimal place value. Many think 0.25 is bigger than 0.3 because 25 is bigger than 3. Line up decimal points and use money to compare.
- Skipping steps. Multi-step problems need written working. Insist on one line per step.
- Rushing. Estimate first. If 29 ร 31 is about 900, an answer of 90 is clearly wrong.

- 02Week 2: Different denominators
Make a common denominator step by step, then use the fraction calculator to check.
- 03Week 3: Decimals in money
Compare and add prices. Round to the nearest rupee.
- 04Week 4: Two-step problems
Three problems a day, written in steps, with an estimate first.

How online maths classes work
- Tell us about your child. Share the class, board, textbook or topic, what feels hard and how much time is available. A parent or guardian makes the enquiry.
- We confirm the fit. We suggest a starting point and confirm the format, time and availability before anything is booked. If an introductory lesson or assessment has a fee, we say so up front.
- Learn, practise and review. Interactive lessons with the child writing and talking, practice between sessions and a short update for parents. We do not promise marks or ranks.

FAQ
Class 5 maths: questions parents ask
Should my Class 5 child start Olympiad preparation?
If they enjoy puzzles and school maths is comfortable, a light start is fine: a few non-routine problems a week, not a heavy syllabus. See our guides on the IMO and Math Kangaroo for what the papers look like.
How can I help with fractions at home?
Cook or cut something together. Halves, quarters and eighths of a chapati or a bar of chocolate are the best fraction lessons, and our Fraction Pizza game makes the same idea visible.
My child makes careless mistakes. Is it carelessness?
Often it is a weak step, not a lack of care. Look at which step goes wrong (place value, borrowing, a table) and practise that step.
Are group or one-to-one classes better?
One-to-one suits catching up and children who are shy. Small groups can be motivating for confident learners. We discuss which fits before you book.
