5. Activity 1 - Perfect match game
 Teachers will choose 5 learners for each group of 2
 Group A members will hold each metacard of a written words
 Group B will hold also a metacard with a written words different from
Group A
 Teachers will instruct the Groups to see their metacard and they will
match each metacard with the other members of the opposite group,
the first couple who match will declare the winner

7. 1. What have you experience on the activity “Perfect Match Game”?
2. What do you observe about the things that are group and match?
3. Why is it necessary to determine the matching of things?
4. How can you say about matching the things in the game and compare it
in the tools and equipment?
GUIDE QUESTIONS

8. 1. Accuracy means how near the instrument reading to its actual value.
2. Amperage means electricity; electrical current flow; and electron flow which is measured at a point within a circuit.
3. Bender is a tool used to make various angles or bends in conduit.
4. Calibration is a technique of testing and adjusting an instrument by referring to another instrument or device of
known accuracy and precision.
5. Chuck is a portion of drill that holds the bit.
6. Cross handle is the handle set across a power tool to prevent the tool from burning.
7. Cutter is a hardened steel device used to cut holes in metal boxes.
8. Die is a component that bucks up cutter on opposite side of the metal box.
9. Cold is the absence of heat. A temperature which is considerably below normal.
10. Ground is an electrical point or any good conductor that is connected to a common chassis with zero relative
voltage. Usually, conductors are connected to the earth.
11. Hydraulic is using pressurized fluid oil to accomplish work.
12. Hydraulic oil is specially formulated oil for hydraulic pumps.
NOTE: No oil or other fluid should ever be used as a substitute hydraulic oil.
13. Knockout punch is a device used to make openings for conduit in metal enclosures.
14. Ram is a device used to transfer hydraulic pressure to a mechanical device.

9. ACTIVITY 2 – “Tool Story”

10. After watching Tool story, You will answer the
following questions?
1.What will the video tell us about the different
tools?
2.What is the cause of accident of all tools and
equipment?
3.How can you give implication about the Tool
Story?

11. Advantages of using the proper tools
1.Efficiency of the work is met.
2.High quality of work is achieved.
3.Speed of accomplishment is faster.
4.Accuracy is obtained.
However, these advantages depend upon the three factors:
 availability and sufficiency of materials
 experience and skill of the workers in their respective fields
 quality of tools and equipment

12. Different kinds of construction tools maybe
classified according to the different kinds of trade
namely:
 carpentry tools
 masonry tools
 tinsmith tools
 painters’ tools
 plumbing tools
 electrical tool

13. General safety rules for using power equipment
 Always follow manufacturer’s operating instructions
 Never place hands in a pinch point.
 Use eye protection.
 Wear gloves when working with hot equipment or materials.
 Always secure loose clothing such as shirt sleeves and shirttails.
 Tie back long hair and do not wear dangling jewelry.
 Never exceed rated capacity of the equipment.
 Never remove protective guards from the equipment.
 Be prepared for an unexpected event.

14. Common Defects of Electrical Power Tools
1. Mechanical Parts
a. Chuck – rusted or stock – up
b. Bearing – worn – out
c. Rotor Shaft – worn – out
2. Electrical Parts
a. Switch (lock, reversing and trigger) – defective
