LESSON PLAN
Subject: ELECTRONICS
Materials needed: Chalk, Blackboard, Eraser, Visual Aids

I. Topic: Resistor Color Coding

II. Objectives
At the end of the lesson, the students will
1. State the colors of the resistor color coding accordingly. 2. Name the value of resistors based on the color codes.
3. Appreciate the value of using codes.

III. Activities
1. Prayer/Greetings/Introduction.
2. Review of the previous topic.
What is resistor?
3. Motivation: Traffic lights
4. Introduce the topic: Resistor Color coding
Ask the students if they can guess the topic today.
5. Introduce the colors involve in resistor color coding. See the visual aid. 6. Give the technique how to remember the colors.

1st color/band: 1st digit
2nd color/band: 2nd digit
3rd color/band: Multiplier
4th color/band: Tolerance
8. Give at least 3 examples on how to read the value of resistor based on its colors. 9. Ask at least 2 students to read the value of resistor based on a given colors. 10. Discuss the designation of the 4 colors/bands resistors. 5 BANDS

1st color/band: 1st digit
2nd color/band: 2nd digit
3rd color/band: 3rd digit
4th color/band: Multiplier
5th color/band: Tolerance
11. Then give at least 3 examples on how to name the colors of resistor from a given resistor value. 12. Ask at least 2 students to name the colors of the resistor based on a given value. 13. Ask the students if they can follow the discussion.

IV. Evaluation
1. Brown, Black, Red, Gold= 1kΩ ±5%
2. Yellow, Violet, Gold, Gold= 4.7Ω ±5%
3. 100kΩ ±10%= Brown, Black, Yellow, Silver
4. Green, Blue, Black, Black, Brown= 560Ω ±1%
5. Orange, Orange, Black, Red, Brown= 33kΩ ±1%
