General Math Lesson Plan 2t464f

LESSON PLAN IN GENERAL MATHEMATICS I. LEARNING OBJECTIVES At the end of the lesson, the students are able to:  represent real-life situations using functions, including piece-wise functions; and  evaluate a function. II. LEARNING CONTENT A. Subject Matter: Functions and Their Graphs B. Lesson:

Functions as Models ( Lesson 1) Evaluating Function ( Lesson 2)

Cooperative Learning

III. LEARNING ACTIVITIES/PROCEDURES A. Preliminary Activity  Prayer  Checking of Attendance  Drill : Integer Flashcard Activity B. Review  What is a function as introduced during your Grade 8 Mathematics? C. Lesson Proper 1. Motivation Present a scenario where functional relationships exist. Solicit additional real-life situations from the students. 2. Presentation Students are divided in groups where they will be given different topics to brainstorm and come up with a creative presentation. Here are the topics to be given: a. Difference of function and relation b. Function as a machine c. Function and relations as a table of values d. Function as a graph in Cartesian plane e. Function as representations of real-life situations f. Evaluation of Functions

3. Discussion Highlight the idea to the students that real-life situations may be represented using functions and need to be evaluated. 4. Developmental Activity The students will be given more examples on functions and will be given more exercises in evaluating functions. 5. Synthesis/Generalization

 

What are the important things to take note about functions? Why is there a need to be careful in evaluating functions?

IV. EVALUATION 1. Write 2 classroom scenarios that represent a function. 2. Evaluate the following: a. x + 4 , where x = 5 b. 2x -3, where x = -2 c. 5 – x, where x = -3 V. ENRICHMENT A math puzzle involving evaluation of functions will be given to students.
