KEY WORDS:
Square, Square root, Pythagorean Triplet, Repeated Subtraction, Factorization, Long Division
CONTENT OF THE TOPIC
Concepts and important facts related to the square and square root.
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.
Show students how to calculate the square root of a number, using examples on the board and a calculator.
