  • 🔬 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
