Ask on WhatsApp - opens WhatsAppClass 6 maths introduces integers and the number line below zero, ratio and proportion, and the first algebra - letters used to stand for unknown quantities. Fractions and decimals are rebuilt as two ways of writing the same thing rather than as separate topics. It is the first year the subject asks for reasoning about quantities a child cannot picture.
Class 6 is the year maths changes character. Everything in primary could be counted, drawn or shared out; a child who could picture the situation could usually get the answer. From Class 6 that stops being true. Integers extend the number line below zero, where nothing is being counted. Algebra puts a letter where a number should be. Ratio compares two quantities without producing a third. Each of these asks a child to reason about something abstract, and the capacity to do that runs out quickly if the arithmetic underneath is still taking conscious effort. That is why a child whose tables are shaky meets Class 6 as a wall rather than a step, and why the useful work in this year is often repair rather than acceleration.

Large numbers, place value into lakhs and crores, estimation and rounding, and the properties of whole numbers - commutativity, associativity, distributivity - stated as rules for the first time rather than used silently.
Factors, multiples, prime and composite numbers, prime factorisation, HCF and LCM. This chapter is the foundation for every fraction simplification that follows, and it is the one most often half-learned.
The number line extended below zero, with addition and subtraction of negatives. The first genuinely abstract idea in school maths: minus three of something that cannot be held.
Rebuilt as two notations for the same quantity rather than as two topics. Addition and subtraction with unlike denominators, and conversion between the two forms.
Letters standing for unknown numbers, forming expressions from word descriptions, and the idea of an equation as a statement of balance rather than an instruction to compute.
Comparing two quantities multiplicatively rather than by difference, and the unitary method - the technique that carries into percentage, speed and every Class 7 comparison.
Points, lines, angles, triangles and quadrilaterals named precisely, plus perimeter and area of rectangles and squares with units handled properly.
Reading and drawing pictographs and bar graphs, and lines of symmetry - the visual topics that carry marks cheaply and are often left until the night before.
Large numbers and estimation, factors and multiples with HCF and LCM, integers on the number line, fractions and decimals treated as one topic, the first algebra, ratio and proportion, basic geometry and mensuration, and data handling. Roughly a third of it is genuinely new; the rest is primary material stated more formally.
The syllabus looks longer than Class 5 and much of it is familiar material being restated with proper names. What is genuinely new is small and concentrated: integers, algebra and ratio. Those three account for most of the difficulty in the year, and they are the three that carry forward hardest.
Two chapters do more work than their length suggests. Playing with numbers - factors, multiples, prime factorisation, HCF and LCM - is the machinery behind every fraction simplification for the next four years, and a child who half-learns it will find Class 7 and 8 fractions unaccountably slow. And ratio and proportion introduces the unitary method, which reappears as percentage in Class 7, as speed and distance later, and in most word problems from here on.
If your child's Class 5 was shaky, the useful move is to check backwards before pushing forwards - see Class 5 maths for what should already be secure.
Because it asks for reasoning about quantities that cannot be pictured - negative numbers, letters standing for unknowns, ratios that compare without producing a third quantity. Abstract reasoning uses working memory, and if arithmetic is still effortful there is no capacity left for it.
Primary maths could always be modelled. Three apples shared between four children is a picture. Class 6 asks about minus three, and about n, and about the relationship between two quantities rather than about either of them. None of that can be drawn in the same way.
The practical consequence is one most families miss. Abstract reasoning consumes working memory, and so does arithmetic that is not yet automatic. A child who has to reconstruct 7 x 8 in the middle of a factorisation has less capacity available for the factorisation itself, so they fail at the new thing while the actual bottleneck is the old thing. This is why fixing tables in Class 6 often improves algebra marks, which looks like a coincidence and is not.
The single highest-value diagnostic this year is therefore backwards, not forwards: are tables and fractions automatic? Our times tables and mental maths sprint are free and take five minutes to answer that question, and this post covers what to do if the answer is no.
Because the minus sign now means two different things - subtraction and negativity - and children are rarely told this explicitly. Most integer errors are not carelessness but an unresolved ambiguity about what the symbol is doing.
In primary, a minus sign is an instruction: take away. In Class 6 it is also a property: this number is below zero. So -3 - 4 contains both meanings in one expression, and a child who has only ever met the first reads it as a subtraction problem they cannot do.
What resolves it is a physical model held consistently, not a rule. Temperature works well because negatives are already familiar there, and so does a number line walked in steps: face the direction the sign tells you, then move. The rules for signs then follow from something the child can check rather than something they must trust.
Worth watching for: a child who gets integer questions right but cannot explain a single one. That is a memorised rule, and it holds until Class 7 introduces multiplication and division of negatives, at which point it silently stops working - which is exactly the pattern described on our Class 7 page.
As generalised arithmetic - a letter is a number whose value we do not know yet, not a label for an object. The 'fruit salad' reading, where a stands for apples, produces correct answers for a term and then breaks completely.
There is a common and damaging shortcut in which 3a + 2a = 5a is explained as three apples plus two apples. It works, briefly. It then makes a x a = a² incomprehensible, because three apples times two apples is not six apples of anything, and it makes substitution meaningless.
The correct framing costs nothing extra at the start: a letter is a number we have not been told. Then 3a + 2a is three of something plus two more of the same something, whatever it turns out to be, and substitution is simply finding out what it was.
Two habits worth building immediately, because they are cheap now and expensive later: write the expression before computing anything, and read an equation as a statement that two sides are equal rather than as an instruction to work something out. The second is what makes solving equations in Class 8 feel like reasoning rather than like following steps.
Because from Class 6 the method carries marks of its own. A child who computes mentally and writes only the answer is discarding marks they earned, and the habit is far easier to change now than in Class 9.
This is one of the most common and most fixable causes of a Class 6 mark drop. Nothing is wrong with the child's maths; the presentation is costing marks that were genuinely earned.
Worth telling your child directly, because most have never been told: showing working is not a formality, it is where a large share of the marks live. Our post on studying hard but getting low marks covers this in more depth, and why marks drop in Class 6 covers the wider transition.
By checking the Class 4 and 5 foundations first, then teaching the three genuinely new ideas - integers, algebra and ratio - with a model the child can check rather than a rule they must trust.
The first session is diagnostic rather than instructional, and it usually looks backwards. Are tables automatic? Can fractions be simplified by spotting a factor? Is place value secure into lakhs? Those three answers determine whether Class 6 content can be taught at all this term, or whether a fortnight of repair comes first. Repair is nearly always faster than pushing on.
After that, the new material is taught from your child's own textbook, in the order their school is covering it, so the tuition supports the class rather than competing with it. We match on board as well as class - CBSE and ICSE handle the Class 6 split differently, and a teacher who does not know that will teach the wrong lesson well.
Free and useful tonight, no sign-up: times tables to 20, the mental maths sprint pitched at Class 6, and printable worksheets with answer keys. The free assessment is 20 minutes and will tell you whether the problem is Class 6 or something two years earlier.

On track by the end of Class 6 looks like
Where it usually goes wrong
Class 6 sits in Class 6 to 8. Separate maths and science streams, taught by specialists.
Per child, per month. See every plan and what is included.
Everything above about the syllabus is checked against the boards’ own material rather than against other tuition sites. If a claim cannot be traced back to one of these, it is not on the page.
Meaningfully, yes - but the step is in the kind of thinking rather than in the volume. Class 6 introduces quantities that cannot be pictured: negatives, letters standing for unknowns, and ratios. A child whose arithmetic is automatic usually copes well; a child still computing effortfully finds it much harder than the syllabus alone would suggest.
Playing with numbers, integers, algebra and ratio. Factors and HCF/LCM are the machinery behind every later fraction; integers and algebra are the first abstraction; ratio introduces the unitary method that reappears as percentage, speed and most word problems.
Usually nothing about the child. Primary maths could be pictured, and Class 6 maths often cannot. If arithmetic is still taking conscious effort there is no working memory left for the new abstract reasoning, so the failure appears at the new topic while the real bottleneck is tables or fractions.
Use temperature or a number line walked in steps rather than the rules for signs. Ask your child to explain why -3 - 4 is -7. If they can produce the answer but not the reason, they have memorised a rule that will stop working in Class 7 when multiplication of negatives arrives.
No. The fruit-salad reading works for a term and then breaks - three apples times two apples is not six apples of anything, so a x a = a² becomes incomprehensible. A letter is a number we have not been told yet, and that framing costs nothing extra at the start.
Not directly - there is no Class 6 board - but the algebra and integer work here is assumed by Class 9 and never retaught. Most Class 9 algebra difficulties trace back to Class 6 or 7 rather than to Class 9 itself, which is why this year is cheap to fix and later years are not.
A group is enough for most children who are broadly keeping up. One-to-one earns its cost when there is a specific gap to close quickly - which is common in Class 6 precisely because the gaps are usually two years old. Both are published on our fees page.
Twenty focused minutes most days beats two hours at the weekend, and the practice should include five minutes of pure arithmetic fluency until it is automatic. Practice on the new abstract topics is worth much less while the arithmetic underneath is still slow.
