🚀 Grade 8 – CBSE Mathematics Curriculum

Grade 8 Mathematics builds a strong foundation for high school and competitive exams. Students explore algebra, geometry, data, and real-world applications through hands-on problem solving and conceptual clarity.

🔢 Number System & Exponents

  • Rational numbers and their properties
  • Laws of exponents (powers with integers and rational bases)
  • Scientific notation and standard form
  • Square and cube roots (manual and prime factorization method)

🧮 Algebra

  • Algebraic expressions and identities
  • Expansion and factorization
  • Solving linear equations in one variable
  • Solving word problems using equations
  • Introduction to linear equations in two variables

➗ Mensuration

  • Surface area and volume of cubes and cuboids
  • Cylinders, cones and spheres (intro concepts)
  • Conversion between units
  • Practical applications in volume and area

📐 Geometry

  • Properties of quadrilaterals and triangles
  • Angle sum property
  • Exterior angle theorem
  • Construction of triangles using given measurements
  • Basic concepts of 3D geometry (edges, faces, vertices)

🔷 Understanding Shapes & Congruence

  • Congruence of triangles (SSS, SAS, ASA)
  • Applications of congruence in solving triangle problems
  • Properties of parallelograms and special quadrilaterals

🔁 Comparing Quantities

  • Percent increase/decrease
  • Profit, loss, discount
  • Simple and compound interest
  • Time and work / time and speed problems

📊 Data Handling & Probability

  • Organizing data in tables and graphs
  • Pie charts, bar graphs, line graphs
  • Measures of central tendency (mean, median, mode)
  • Introduction to probability (basic events, equally likely outcomes)

📈 Introduction to Graphs

  • Cartesian plane and plotting points
  • Linear graphs and interpretation
  • Graphs from real-life data (distance-time, temperature-time, etc.)

🧭 Practical Geometry (Using Tools)

  • Construction of quadrilaterals with given sides and angles
  • Angle bisectors, perpendicular bisectors
  • Drawing with ruler, compass, and protractor

🎯 Learning Goals by the End of Grade 8

  • Confidently solve algebraic expressions, equations, and geometry problems
  • Apply math to real-world scenarios (finance, measurement, data)
  • Build strong reasoning skills for board exams and Olympiads
  • Prepare for Grade 9 and competitive math topics
