PROCEDURE & EXPLANATION
Introduction
Begin the lesson by asking students what they know about squares and square roots.
Write down their responses on the board and clarify any misconceptions.
Explain that squares and square roots are important mathematical concepts that are used in many fields of science and engineering.
Understanding Squares
Define what a square is: "A square is a number that is obtained by multiplying a number by itself."
Give examples of squares, such as 1^{2} = 1, 2^{2} = 4, 3^{2} = 9,
and 4^{2} = 16
Explain that squares have many practical applications, such as in measuring area and calculating distances.
Calculating Squares
Show students how to calculate the square of a number, using examples on the board and a calculator.
Have students solve problems related to calculating squares, using worksheets or problems on the board.
Understanding Square Roots
Define what a square root is: "A square root is the inverse operation of squaring. It is the number that, when multiplied by itself, gives the original number."
Give examples of square roots, such as √1 = 1, √4 = 2, √9 = 3, and √16 = 4.
Explain that square roots also have many practical applications, such as in calculating side lengths of squares and finding distances.
Arrange the students either in groups
or individuals and plan an activity of writing the squares of natural numbers
from 1 to 30. Also help students to find the square of other important numbers
like 35, 40, 45, 50, 55 ….. etc.
Teacher may also suggest some
shortcut ways of finding square of such numbers
Calculating Square Roots
Show students how to calculate the square root of a number, using examples on the board and a calculator.
Have students solve problems related to calculating square roots, using worksheets or problems on the board.
Help the students to find the square root by using different methods
like
 Repeated subtraction method of finding the square root of a number.
 Factorization method of finding the square root of a number.
 Long division method of finding the square root of a number.
 Method of estimation of finding the square root
of a number.
Application of Squares and Square Roots
Give reallife examples of how squares and square roots are used in everyday life, such as in measuring the size of a room or calculating the distance between two cities.
Have students work in groups to come up with their own examples of how squares and square roots are used in practical situations.
MIND MAP / CONCEPT MAP
SKILLS ENHANCED
