Powerpoint for Radicals

1. PRAYER

2. CHECKING OF ATTENDANCE

3. Review / Drill Simplify the following radicals: What do you notice when simplifying radicals?  

4. Why is adding or subtracting radicals important in real life?

5. Addition & Subtraction of Radicals

6. Objectives 1. Simplify, add, and subtract radicals. 2. Work cooperatively in groups showing fairness, respect, and responsibility. 3. Use ICT tools (interactive quiz / game) in practicing addition and subtraction of radicals. 4. Apply concepts of radicals in solving real-life problems.

7. Like Radicals or Unlike Radicals

8. Like Radicals Definition: Like radicals have the same index and radicand. Rule: Add/Subtract coefficients and rewrite the radical only. Examples: √5 + 3√5 = 4√5 2√3 – √3 = √3

9. Unlike Radicals Reminder: Unlike radicals cannot be combined directly. Example: √8 + √18 – √50 Simplify radicals first, then combine if possible.

10. Guided Practice (Group Work) Work in groups of 4–5 members. Solve problems on manila paper. Present your answers and give peer feedback.

11. ICT Integration – Interactive Quiz Join our Quizizz/Kahoot activity! Scan the QR code or use the link provided. Answer 5 items on addition and subtraction of radicals.

12. Application Problem: An engineer calculates √64 m² and √36 m². How much larger is the first area than the second? Solve individually, then compare with your seatmate.

13. Generalization Q1: When can we add or subtract radicals? Q2: What happens with unlike radicals?

14. Evaluation Answer the following: 1. 2√7 + 5√7 2. √12 – 2√3 3. √8 + √18 – √50 4. 3√2 + 4√5 – √2 5. A square garden has area 48 m² and another 75 m². Find the difference between their sides.

15. Assignment Research: Find at least one real-life situation where radicals are added or subtracted. Write and solve it. “Mathematics is not about numbers, equations, or algorithms: it is about understanding.”
