Good Grade 7 mathematics revision starts with knowing exactly what the year covers. Grade 7 is the first year of junior school, and its Mathematics lays the base for KJSEA at the end of Grade 9. This guide lists all five strands and 18 sub-strands in the KICD design, shows where the most lessons go, works through typical questions and ends with a four-week plan.

What Grade 7 Mathematics Covers
The revised KICD Grade 7 Mathematics curriculum design suggests 150 lessons across five strands. Junior school has five Mathematics lessons a week of 40 minutes each.
| Strand | Sub-strands (suggested lessons) | Total |
|---|---|---|
| 1.0 Numbers | Whole Numbers (20), Factors (7), Fractions (9), Decimals (6), Squares and Square Roots (5) | 47 |
| 2.0 Algebra | Algebraic Expressions (5), Linear Equations (6), Linear Inequalities (8) | 19 |
| 3.0 Measurements | Pythagorean Relationship (4), Length (6), Area (8), Volume and Capacity (8), Time, Distance and Speed (8), Temperature (6), Money (14 in the summary table) | 54 |
| 4.0 Geometry | Angles (8), Geometrical Constructions (12) | 20 |
| 5.0 Data Handling and Probability | Data Handling (10) | 10 |
Measurements and Numbers take two-thirds of the year. If revision time is short, start there.
Strand by Strand: What to Revise
Numbers
Whole numbers go up to hundreds of millions, with place value, total value, rounding and the four operations. Factors include divisibility tests, GCD and LCM. Fractions and decimals cover all four operations and real-life use.
Try: find the LCM of 12, 18 and 30. Prime factors: 12 = 2² × 3, 18 = 2 × 3², 30 = 2 × 3 × 5. Take the highest power of each: 2² × 3² × 5 = 180.
Algebra
Learners form and simplify expressions, solve linear equations in one unknown, and work with linear inequalities on a number line. Inequalities get more lessons than equations, so do not skip them.
Try: solve 3x − 4 < 11. Add 4: 3x < 15. Divide by 3: x < 5. Show it on a number line with an open circle at 5 and an arrow to the left. More practice is in our linear equations revision.
Measurements
This is the biggest strand. It covers the Pythagorean relationship, conversion of units of length, area, volume and capacity, time, distance and speed, temperature, and money: profit and loss, discount, commission, household bills, postal charges and mobile money transactions.
Try: a matatu travels 90 km in 1 hour 30 minutes. Speed = 90 ÷ 1.5 = 60 km/h. A common mistake is dividing by 1.3 instead of 1.5. For right-angled triangles, see Pythagoras theorem revision.
Geometry
Measuring and drawing angles, then constructions with a ruler and a pair of compasses only: bisecting angles, constructing 90°, 45°, 60° and 30° (and other multiples of 7.5°), triangles and circles. Constructions have 12 suggested lessons, so practise them physically, not just by reading.
Data Handling and Probability
Collecting data, frequency distribution tables, choosing a suitable scale, and drawing and interpreting pictographs, bar graphs, line graphs, pie charts and travel graphs. Check that scales and labels are correct; many marks go there.
Five Mistakes That Cost Grade 7 Marks
- Mixing up place value (the digit’s position) and total value (digit × position).
- Adding fractions by adding the denominators.
- Forgetting to change units before calculating area or speed.
- Drawing inaccurate constructions because the pencil is blunt or the compass slips.
- Skipping working. Method marks matter in school-based assessment.
Why Grade 7 Revision Matters Now
Grade 7 learners sit school-based assessments set by KNEC. As reported by Pulse Kenya, KNEC’s 2026 school-based assessment guidelines listed Mathematics among the Grade 7 written assessments. These scores feed into the junior school record that matters later, so steady revision pays.
A Four-Week Grade 7 Mathematics Revision Plan
- Week 1, Numbers: one sub-strand a day, ten questions each, with corrections.
- Week 2, Algebra and Geometry: equations and inequalities on Monday to Wednesday, constructions on Thursday and Friday.
- Week 3, Measurements: two sub-strands a day, starting with Money and Time, Distance and Speed.
- Week 4, Data and mixed papers: one graph topic, then a full timed paper every other day.
Keep an error book: every wrong answer, the correct working and one line on what went wrong.
Practise With Real Grade 7 Questions
Start with free questions on the Grade 7 Mathematics revision papers page and a quick round on the Grade 7 CBC Challenge. The Grade 7 hub links every learning area. Full papers with worked answers and the Grade 7 holiday pack open with the Monthly Pass (KSh 500 by M-Pesa), and every question is checked by a teacher.

Frequently Asked Questions
What are the strands in Grade 7 Mathematics?
Numbers, Algebra, Measurements, Geometry, and Data Handling and Probability. Together they have 18 sub-strands and about 150 suggested lessons.
Which Grade 7 Mathematics topic has the most lessons?
Whole Numbers, with 20 suggested lessons, followed by Money with 14 and Geometrical Constructions with 12.
How many Mathematics lessons does Grade 7 have per week?
Five lessons a week, each 40 minutes, under the Ministry’s junior school timetabling guidelines.
Is Grade 7 Mathematics examined by KNEC?
Grade 7 learners sit KNEC school-based assessments, which include Mathematics. The national KJSEA comes at the end of Grade 9.
How long should a Grade 7 learner revise Maths each day?
About 30 to 40 minutes on school days is enough if it includes practice questions and corrections, with a timed paper every week or two.
