Course description

Class 7th Mathematics introduces students to deeper concepts of numbers, algebra, geometry, and practical applications of math in daily life. The syllabus covers topics like integers, fractions and decimals, simple equations, ratios and proportions, lines and angles, perimeter and area, symmetry, data handling, and practical geometry. Through problem-solving, logical reasoning, and real-life examples, students strengthen their analytical thinking and prepare for advanced mathematical learning in higher classes.

What will i learn?

  • Application of Substitution – Students learn how to replace a variable with a given value in an expression. Concept of Squaring – Reinforces the idea of exponents, i.e., π‘₯ 2 = π‘₯ Γ— π‘₯ x 2 =xΓ—x. Order of Operations – Builds accuracy in following BODMAS (brackets, orders, division/multiplication, addition, subtraction). Algebra to Arithmetic Connection – Shows how algebraic expressions turn into simple numbers when values are substituted. Problem-Solving Accuracy – Improves step-by-step simplification skills. Confidence in Algebra – Strengthens the foundation for solving bigger algebraic expressions and equations in higher classes.

Requirements

  • Knowledge of Substitution – Students must replace π‘₯ x with the given value (3). Understanding of Squares – They need to calculate π‘₯ 2 x 2 correctly ( 3 2 = 9 3 2 =9). Order of Operations (BODMAS) – Apply brackets, multiplication, addition, and subtraction in the correct sequence. Simplification Skills – Multiply, add, and subtract numbers step by step without errors. Algebraic Expression Handling – Recognize that the given is an algebraic expression and solve it for a specific value of the variable.
