ACTIVITY 2 IN MATHEMATICS 9 FOR LEARNING PLAN
- 2. SAMPLE FOOTER TEXT 2 GROUP DISCUSSION INSTRUCTIONS: TRANSLATING VARIATION BETWEEN TWO QUANTITIES Objective By the end of this discussion, you should be able to: •Identify different types of variation (direct, inverse, joint, combined) between two or more quantities. •Translate real-life situations into mathematical relationships or equations. •Use these relationships to predict changes in one quantity when another quantity changes.
- 3. SAMPLE FOOTER TEXT 3 Exploring Types of Variation (15 minutes) •Direct Variation: When one quantity increases, the other also increases proportionally. Discuss an example where this is true and how you would express this mathematically. •Inverse Variation: When one quantity increases, the other decreases. Share an example, and discuss how this relationship could be written. •Joint Variation: Some situations depend on more than one variable (e.g., area of a rectangle as length ×times× width). How would you write a relationship like this? •Combined Variation: This combines direct and inverse variations. Consider how we might express a situation with both types.
- 4. SAMPLE FOOTER TEXT 4 Translating Situations to Equations (10 minutes) •Each group will get a set of real-life situations. For each, identify the type of variation and write a mathematical equation to represent it. •Example: “The cost of printing varies directly with the number of pages printed.” • (Answer: Cost=(k)(Pages)
