Procedure Teacher’s activity a. Preliminary activities Good morning class… “Let us pray first… (Checking of Attendance)… Attendance)… say present… “Please pick up the piece of paper under your chair … “So How was your Day? Da y? “That’s good! Have you enjoyed your bonding with your family and friends? “OK! A brief recall of our discussion last week, is resistor? (OK! Mr. john Carlo?) “Thank you!! For you!! For wonderful answer)… “OUR discussion for today… (resistor color coding)
Student’s activity Good morning, Sir! (one student will lead the prayer) (student raise their hand and say present as the teacher call their name) (student pick up the piece of paper) “Answer varies… “Of course Sir It was a lot of fun…
( student raise their hand) (Carlo will answer the question)
(student will listen)
b. Motivation …who among of you see a traffic light? .. A traffic light has deferent colors like resistor… c. Lesson proper (introduce the color in resistor color coding ) (Give the technique how to remember the color code ) (Discuss the designation of the four color/ bands) st nd (four bands: 1 digits, 2 digit, rd th 3 multiplier, 4 tolerance ) (three example on how to read the values of resistor based on the color ) (Another is designation of the four color bands resistor five bands ... st nd rd 1 color/band, 2 color/band, 3 th color/band multiplier, 4 color/band tolerance) d. Generalization Class what have you learned from previous lesson? e. Application “Ok! I have three resistors. Who can give the values of this three resistor? 1. Brown, black, red, gold? 2. Yellow, violet, gold, gold? 3. Brown, red, red, gold? ...no.1 Mark can you answer number 1? …Correct, Ok number 2, yes? …Correct, how about number 3, yes Dan? (correct ! thank you Dan )
(the student will raise their hand)
(the student try to analyze the lesson )
(student will share their ideas on they have learned in the lesson)
(student raise their hand ) 1. Brown, black, red, gold. 2. Yellow, violet, gold, gold. 3. Brown, red, red, gold. … (Sir 1kΩ5%). … (Sir 4.7Ω5%). … (Sir 12kΩ5%).
None! Sir…
IV.
Evaluation Get ½ sheet of paper answer the following: 1. 1kΩ5% 2. 4.7Ω5% 3. Brown, black, yellow, silver 4. Green, blue, black, gold 5. 33kΩ5% ___________
(student get their paper) 1. 1kΩ5% brown, black, red, gold 2. 4.7Ω5% orange, gold, violet, gold. 3. Brown, black, yellow, silver 10kΩ10% 4. Green, blue, black, gold 56Ω5%
5. 33kΩ5% yellow, black, red, gold

Procedure Teacher’s Activity a. Preliminary activities “Good morning Class” “Let us start this day by thanking God and ask for guidance, Mr. Mark Please lead the prayer. (Ms. Secretary May I know who are the absent for today) b.

Lesson proper “Our topic deals about steps in designing a PCB. (the student will raise their hands) (Now we are going to study the process of PCB designing, but before knowing the process of designing. Let’s define first What a PCB is, Anyone who has idea? ) (Pick up two student from each group) “Thank you Please is noted that that those students who are participating will get extra point for recitation. “Going back to the lesson, the printed circuit board or PCB is a card made specifically for attaching electronics component. :PCB serves two purpose: 1. It is a place to mount component. 2. It provides the meant of electrical component.
