Grade 7 CBC Mathematics 2026: All Strands, Sub-Strands and What to Study Each Term

Information current as of Term 2, 2026.

Grade 7 Mathematics under Kenya's Competency Based Education (CBE) system is organised into strands and sub-strands: never chapters and topics as under the old 8-4-4 system. If you are a parent, teacher or Grade 7 learner trying to understand exactly what is covered and when, this guide gives you the full picture for 2026, including worked examples, a term-by-term planning table, and the mistakes that cost learners the most marks.

Why CBC Maths Uses "Strands" Not "Topics"

KICD uses the language of strands and sub-strands to emphasise that mathematical thinking is interconnected, not a series of isolated topics ticked off and forgotten. A strand like Numbers runs throughout the entire year, deepening in complexity each term rather than being "finished" in Term 1 and abandoned. This is a deliberate design choice to build mastery over time: see What Are Strands and Sub-Strands in CBC (CBE)? for the full rationale behind this terminology shift away from 8-4-4 language.

Strand 1: Numbers

Numbers is the foundational strand and occupies the most time in Grade 7. Sub-strands include:

• Integers: directed numbers, number lines, operations with negative numbers
• Fractions: equivalent fractions, operations, mixed numbers, word problems
• Decimals: place value, conversion, operations, rounding
• Squares, Square Roots, Cubes and Cube Roots: computation and application
• Indices: laws of indices, scientific notation
• Ratio and Proportion: sharing in ratios, direct and inverse proportion
• Percentages: percentage of quantities, profit, loss, discount, VAT

Numbers concepts appear in approximately 35–40% of any Grade 7 Maths examination or assessment. Learners who are weak in Numbers will struggle across every other strand, because Algebra, Geometry and Measurements all assume fluent number work as a foundation.

Worked Example: Percentages

Question: A shop sells a school bag at KSH 1,800 after giving a 20% discount off the original price. What was the original price?

Solution, step by step:

1. The sale price represents 100% − 20% = 80% of the original price.
2. Let the original price be P. Then 80% of P = 1,800.
3. Write this as an equation: 0.8 × P = 1,800.
4. Divide both sides by 0.8: P = 1,800 ÷ 0.8 = 2,250.
5. Answer: the original price was KSH 2,250.

This is exactly the kind of multi-step, real-world percentage problem that recurs in Grade 7 assessments: learners who only practise "find 20% of 1,800" without practising the reverse calculation often lose marks here.

Strand 2: Algebra

Algebra introduces learners to abstract mathematical thinking. Grade 7 sub-strands include:

• Algebraic Expressions: simplifying, expanding brackets, collecting like terms
• Linear Equations: solving one-variable equations, forming equations from word problems
• Linear Inequalities: representing on number lines, solving simple inequalities
• Sequences and Patterns: finding the nth term, arithmetic sequences

Worked Example: Linear Equations

Question: Solve for x: 3x + 7 = 22.

Solution, step by step:

1. Subtract 7 from both sides: 3x = 22 − 7 = 15.
2. Divide both sides by 3: x = 15 ÷ 3 = 5.
3. Answer: x = 5. Check: 3(5) + 7 = 15 + 7 = 22: correct.

Algebra is heavily tested because it underpins higher Mathematics. Learners who struggle with algebra in Grade 7 typically find Grade 8 and Grade 9 Mathematics very difficult, since both grades build directly on these one-variable equation skills: see CBC Grade 8 Mathematics Revision Notes for how the algebra strand develops in the following year.

Strand 3: Geometry

Geometry develops spatial reasoning and logical proof. Sub-strands include:

• Angles and Lines: types of angles, parallel lines, transversals, angle sums
• Triangles: classification, Pythagoras' theorem, congruence
• Quadrilaterals and Polygons: properties, angle sums, area
• Circles: parts of a circle, circumference, area
• Transformations: reflection, rotation, translation, enlargement on a grid
• Construction: using compasses and ruler to construct angles and shapes

Worked Example: Angles on a Straight Line

Question: Two angles lie on a straight line. One angle is 3x degrees and the other is (x + 40) degrees. Find the value of x and the size of each angle.

Solution, step by step:

1. Angles on a straight line add up to 180 degrees, so 3x + (x + 40) = 180.
2. Combine like terms: 4x + 40 = 180.
3. Subtract 40 from both sides: 4x = 140.
4. Divide both sides by 4: x = 35.
5. The two angles are 3(35) = 105 degrees and (35 + 40) = 75 degrees.
6. Check: 105 + 75 = 180: correct.

This question combines Algebra and Geometry, which is exactly the kind of cross-strand application KJSEA-style assessments reward: see the worked Algebra example above for the equation-solving skill this question depends on.

Strand 4: Measurements

Measurements connects Mathematics to real life. Sub-strands include:

• Length, Mass and Capacity: units, conversions, calculations
• Area and Perimeter: composite shapes, real-world applications
• Volume and Surface Area: cuboids, cylinders
• Time and Speed: average speed, distance-time calculations
• Money and Financial Literacy: budgeting, interest, currency conversion

Strand 5: Data Handling and Probability

This strand builds statistical literacy. Sub-strands include:

• Data Collection and Presentation: frequency tables, bar charts, line graphs, pie charts
• Measures of Central Tendency: mean, median, mode
• Probability: simple events, experimental vs theoretical probability

What Is Covered Each Term

KICD's Grade 7 Mathematics Scheme of Work distributes the strands across three terms approximately as follows:

Some schools adjust the pace based on their learners' needs. If your child's school is ahead or behind this sequence, that is normal: the KICD Scheme of Work is a guide, not a rigid law. For a full term-by-term planning document rather than just the headline distribution, see the CBC Grade 7 Schemes of Work 2026 template.

Case Study: Brian's Algebra Turnaround in Eldoret

Take Brian, a Grade 7 learner at a school in Eldoret. By the end of Term 1, his teacher's CBA record showed AE (Approaches Expectation) in Algebra, even though he was scoring ME in Numbers. His parents initially assumed Maths was simply "not his subject." A closer look at his marked exercise book showed the real issue was narrower: Brian could simplify expressions correctly but consistently made sign errors when solving equations with negative coefficients: a single, fixable sub-strand gap, not a general weakness. Ten minutes of daily targeted practice on solving equations (not redoing Numbers work he had already mastered) moved him to ME by the Term 2 assessment. The lesson: a CBA band tells you something is wrong in a strand, but only the exercise book tells you exactly what.

Common Mistakes Grade 7 Learners Make in Mathematics

• Skipping working in Algebra and Geometry. CBA and written assessments reward shown method: a correct final answer with no working can lose marks.
• Confusing "topic" language from older siblings' 8-4-4 books with current strand terminology, which can cause real confusion when self-studying from mismatched resources.
• Treating Numbers as "finished" after Term 1. Because Numbers reappears with new sub-strands every term, gaps from Term 1 silently resurface in Term 2 and Term 3.
• Memorising formulae for Measurements without understanding units. Mixing up centimetres and metres mid-calculation is one of the most common avoidable errors.
• Practising only easy questions. Confidence-building is good, but learners need to attempt harder multi-step word problems regularly, not just repetition of simple drills.

How to Support Grade 7 Maths Revision at Home

1. Identify the weak sub-strand, not just the weak strand. "Algebra" is too broad a target: "solving equations with negative numbers" is something you can actually fix in a week.
2. Practise little and often. 15–20 minutes daily produces better retention than one long Sunday session.
3. Use real past papers and marking schemes so learners see exactly how marks are awarded for working, not just final answers.
4. Connect Maths to daily life: shopping discounts, M-Pesa transaction calculations and matatu fare splitting are all genuine Grade 7 Numbers and Ratio practice.
5. Check in every term, not just before exams, since strands compound across the year.

Frequently Asked Questions

Do Grade 7 learners sit formal exams?

Yes. Junior Secondary (Grade 7–9) includes formal end-of-term assessments alongside continuous school-based assessment. Unlike lower primary (Grade 1–3), Grade 7 learners do sit written tests.

How is Grade 7 Maths graded?

School-based assessments use the four-level competency scale: EE (Exceeds Expectation), ME (Meets Expectation), AE (Approaches Expectation), BE (Below Expectation). End-of-term tests may also use percentage marks converted to these levels: see What Do BE, AE, ME and EE Actually Mean? for a full explanation of each band.

My child struggles with algebra: what should I do?

Start with the basics: confirm they can simplify expressions and solve simple one-step equations before moving to word problems. Daily practice of 10–15 minutes on algebra alone is more effective than one long weekly session covering everything.

Which strand carries the most marks in Grade 7 Maths?

Numbers, typically around 35–40% of any given assessment, followed by Algebra and Geometry. This is why a learner who is weak in Numbers tends to underperform across the whole subject, not just one strand.

Is Grade 7 Maths harder than the old Standard 7 syllabus?

The content overlaps substantially, but CBC's Grade 7 Maths places more emphasis on application and word problems rather than recall, in line with KJSEA's competency-based question style: see the KJSEA 2026 guide for how this question style carries through to Grade 9.

Where can I get a full term-by-term Grade 7 Maths plan?

See the Grade 7 KICD Curriculum Design Walkthrough for a strand-by-strand planning guide, or download full notes and schemes directly.

How many marks come from Geometry compared with Numbers?

Geometry typically carries slightly less weighting than Numbers: roughly 20–25% of a Grade 7 Maths assessment, compared with 35–40% for Numbers: but Geometry questions often combine with Algebra, so a learner weak in equation-solving can lose marks in what looks like a "Geometry" question.

Should my child use a calculator for Grade 7 Maths?

Most Grade 7 school-based assessments expect learners to calculate by hand to build genuine number sense. Check with your child's specific school on its calculator policy, since this varies and is not centrally mandated at this grade.

Bottom Line for Parents and Teachers

Grade 7 Mathematics rewards consistent, strand-aware revision far more than last-minute cramming. Numbers and Algebra deserve the most attention because every other strand depends on them. Identify the specific sub-strand gap, not just the general subject weakness, and practise that gap directly.
