PROCEDURE & EXPLANATION

[Click Here For Complete Explanation]

Start the session by checking their previous knowledge, by asking the questions related to the topic. After this explain the topic to the students.

Introduction and motivation

Teacher will start the session by giving many examples of Algebraic Expressions. Now teacher will explain which types of Algebraic Expressions are called Polynomials. After this teacher will introduce the definition of Polynomial and explain the different components of polynomials.

Polynomial: An algebraic expression in which the exponent of the variable is a whole number is called a polynomial.

Example: 3x² + 5,  4x³ - 8x² + 5x - 3,  5x⁴ + 3x²   are some examples of polynomial .

Important Definitions

Now teacher will explain the Important Definitions like Degree, coefficients and zeroes of the polynomials and their graphical representations.

Degree of constant polynomial is zero and degree of zero polynomial is undefined.

After this teacher will explain the different types of polynomial on the bases of degree and on the basis of number of terms. 

 Teacher will also give examples  and explanations of definitions of the polynomials like linear, quadratic, cubic, bi-quadratic, monomial, binomial, and tri-nomial .

Finding Zeroes from the Graph

Students will be given the knowledge of finding the number of zeroes from the graph of the polynomial.

Number of zeroes of a polynomial is equal to the number of times the graph of that polynomial meet the x - axis.

Graph of a quadratic polynomial is always parabolic.

Zeroes of Quadratic Polynomial

Now teacher will explain the Factor method of finding the zeroes of quadratic polynomials and will explain the Relationship between zeroes and coefficients. 

Teacher will also provide some problems to the students to check whether students can apply the method or not.

Now teacher will explain the method of finding the quadratic polynomial from the zeroes and explain the topic by taking some examples.

Division Algorithm

By taking some examples, teacher will explain the method of dividing one polynomial by another. To verify the result of division teacher will explain the Division Algorithm.

Dividend = Divisor ❌ Quotient + Remainder

Zeroes of Bi-Quadratic Polynomial

Now teacher will explain the method of finding all zeroes of bi quadratic polynomials by using factor theorem and division algorithm. Method will be well explained by taking examples. 

Teacher can also give some problems to the students to check whether they will understand the concept or not.

Zeroes of Cubic Polynomial

Now concept of cubic polynomial is also be introduced. Students will be given the knowledge of cubic polynomial, its general form, its zeroes and the relationship between zeroes and coefficient.

STUDENTS DELIVERABLES:-

• Review questions given by the teacher. 
• Student can prepare the presentation on the topic relationship between zeroes and coefficients for quadratic as well as cubic polynomials. 
• Solve NCERT problems with examples, 
• Solve assignment on Multiple Choice Questions (MCQ) given by the teacher.

MIND MAP

EXTENDED LEARNING:-

Students can extend their learning through the RESOURCE CENTRE and can find more valuable and interesting concepts on mathematics at  cbsemathematics.com

ASSESSMENT TECHNIQUES:-

Assignment sheet will be given as home work at the end of the topic. Separate sheets which will include questions of logical thinking and Higher order thinking skills will be given to the above average students.

 Class Test , Oral Test , MCQ worksheet and Assignments can be made the part of assessment.

Re-test(s) will be conducted on the basis of the performance of the students in the test.
