Lesson Plan in Mathematics (Grade 8)
June 17, 2015
I. Objective
At the end of the period, the students should be able to get the product of cubing a binomial.
II. Subject Matter
A. Topic: Special Products
B. References: Grade 8 Module 1,p.17
Elementary Algebra
C. Materials: FlashCard
D. Strategies: Brainstorming, Discussion
E. ValueFocus: Patience
II. Development of the Lesson
A. Review (Oral Recitation)
Give example items of cube a binomial
B. Motivation (Math Game)
Have a short spelling contestusing
C. Lesson Proper (board work and discussion)
➢ Given their examples, ask for 3 volunteers to answer the given items
➢ Then let them explain the process of getting the product of cubing a binomial..
➢ Insert during discussion, they need patience in solving in order to get the correct answer.
D. Practice(think-pair-share)
1. (m+4) 3
2. (n-2) 3
3. (2s+3) 3
E. Generalization
The students should be able to conclude that “To find the cube of a binomial, we need to:
a. Find the cube of each term to get the first and last term;
b. The second term is three times the product of the square of the first term and second term;
c. The third term is three times the product of the first term and the square of the second
term
F. Application
Think of objects/ things where you can apply cubing of binomial in real life situation.
IV.Evaluation
Let the students get the product cubing binomials using the patterns they have learned
