Number System & Basic Operations
- Reading, writing, and comparing numbers up to 6–7 digits (including Indian system: lakhs, crores)
- Place value and estimation of large numbers
- Roman numerals (basic understanding)
- Whole numbers: addition, subtraction, multiplication, division
- Factors and multiples
- Prime and composite numbers
- Prime factorization (using factor tree)
- HCF (Highest Common Factor / GCD) and LCM (Lowest Common Multiple) — very important
- Divisibility rules (2, 3, 4, 5, 6, 9, 10, 11)
Fractions
- Types: proper, improper, mixed fractions
- Equivalent fractions
- Comparing and ordering fractions
- Addition and subtraction of fractions (same & different denominators)
- Multiplication of fractions (fraction × whole number, fraction × fraction)
- Division of fractions (basic idea: multiply by reciprocal)
Decimals
- Understanding decimal place value (tenths, hundredths)
- Reading, writing, and comparing decimals
- Converting fractions to decimals and vice versa
- Addition and subtraction of decimals
- Multiplication of decimals (by whole numbers and by 10, 100, etc.)
- Division of decimals (basic)
Basic Algebra Introduction
- Use of variables / letters to represent unknown numbers
- Simple patterns and forming simple expressions (very basic exposure from Class 6)
Geometry Basics
- Basic geometrical ideas: point, line, line segment, ray
- Types of angles (acute, obtuse, right, straight, reflex)
- Measuring angles with protractor
- Understanding elementary 2D shapes (triangle, quadrilateral, circle) and their elements (sides, vertices, etc.)
- Symmetry (line symmetry in simple figures)
- Representation of 3D shapes on 2D paper (basic nets / views)
Mensuration (very basic level)
- Perimeter of simple shapes (square, rectangle, triangle)
- Area of rectangle and square
- Idea of volume (only concept, not deep calculation)
Ratio & Proportion (introductory)
- Concept of ratio
- Simple equivalent ratios
- Basic unitary method (very simple)
Data Handling (introductory)
- Collection and organization of data
- Pictographs and bar graphs
- Reading and interpreting simple graphs
Other Important Skills
- BODMAS / PEMDAS rule (order of operations)
- Word problems involving all four operations
- Basic problem-solving and logical reasoning
Most critical prerequisites for smooth transition to Class 7
(these appear repeatedly in Class 7 chapters like Integers, Fractions & Decimals, Rational Numbers, Simple Equations, Lines & Angles, Algebraic Expressions, etc.):
- Good command over fractions & decimals operations
- HCF / LCM mastery
- Prime factorization
- Basic angle measurement & types of angles
- Perimeter & area of rectangle/square
- Understanding of variables & simple patterns
- Comfort with negative numbers concept (even if not fully taught, basic idea helps)
If your child is weak in any of these (especially fractions, decimals, HCF/LCM, or basic geometry), it's best to revise Class 6 NCERT chapters first — particularly Chapters 1–8 from the old NCERT Class 6 book or the relevant units from the new Ganita Prakash textbook.
This foundation makes topics like negative numbers (integers), rational numbers, algebraic expressions, equations, and geometry in Class 7 much easier. Let me know if you'd like resources or specific revision tips for any of these!
