Grade 4 is the first year of upper primary under CBC, and Mathematics changes gear. Learners move from counting and simple sums to place value in the thousands, written multiplication and division, fractions and real measurement. Many children who coasted in Grade 3 hit a wall here, usually because one foundation skill was never secured. This guide shows parents how to find that gap and close it with short, regular revision at home. The full list of topics is in KICD’s Grade 4 curriculum designs, under Mathematics.

What Grade 4 Mathematics Covers
The Grade 4 Mathematics curriculum is organised into strands. Most schools teach them in roughly this order:
- Numbers: whole numbers up to 10,000, place value, reading and writing numbers in words and figures, rounding, addition and subtraction with regrouping, multiplication and division, and an introduction to fractions.
- Measurement: length in metres and centimetres, mass in kilograms and grams, capacity in litres and millilitres, time (including the 12-hour clock) and money in Kenya shillings.
- Geometry: lines, angles, and properties of common 2D shapes.
- Data handling: collecting data, pictographs and simple tables.
Your child’s teacher may order these differently, so ask for the term’s scheme of work or check the exercise book to see what has been covered.
Start With a Five-Minute Check
Before buying books or booking tuition, sit with your child for five minutes and ask them to do four things: write 4,706 in words, work out 368 + 457, work out 6 × 7 without counting on fingers, and say what half of 18 is. If they struggle with place value, that is the root of most later errors. If multiplication facts are slow, written multiplication and division will stay painful until they are automatic.
A Weekly Revision Rhythm
Ten to fifteen focused minutes a day beats a two-hour Saturday session. A simple pattern that works for many families:
- Monday: place value and number words, using price tags or receipts.
- Tuesday: times tables, a few at a time, said aloud and then written.
- Wednesday: addition and subtraction with regrouping, five questions only, checked together.
- Thursday: measurement in the kitchen, such as measuring water in a jug or weighing flour.
- Friday: one short practice paper or worksheet, marked together.
Turn Everyday Life Into Maths
CBC deliberately ties Mathematics to real situations, and the assessments do the same. Let your child count change at the kiosk, read the time on an analogue clock, compare prices per kilogram at the market, or work out how many days remain until school reopens. These moments build the reasoning that word problems test, and they cost nothing.
Common Grade 4 Mistakes
- Misaligning digits in column addition, which comes from weak place value.
- Forgetting to carry or borrow across a zero, as in 503 − 268.
- Mixing up grams and kilograms, or centimetres and metres.
- Reading word problems too quickly and choosing the wrong operation.
When you mark work, ask your child to explain their steps out loud. You will often hear the exact moment the mistake happens, and correcting the thinking is more useful than correcting the answer.
Use Practice Papers Wisely
Practice papers are most useful after a topic has been revised, not as a first step. Use the cbcguide revision papers to test one strand at a time, then a mixed paper at the end of the month. Look at the Grade 4 hub for all Grade 4 learning areas, and the holiday homework page for packs to use during school breaks. Our free tools also help you keep track of term dates and fees.
When to Ask the Teacher
If your child still struggles with the same topic after two or three weeks of steady practice, speak to the class teacher. Teachers see how your child works in class and can tell you whether the problem is understanding, speed or confidence. Bring a sample of the home practice so the conversation is concrete.
Keep Confidence High
Many Grade 4 learners decide early that they are “bad at Maths”, and that belief does more harm than any single weak topic. Start each session with a question you know your child can answer, praise clear working as much as correct answers, and end on a success. Short, calm, regular practice is the habit that carries a child through upper primary.
