12. “YOU BELONG WITH ME” Each group will have an illustration board and paper strips. All the names of tools, equipment, and materials in technical drafting are written in the paper strips. c lassify the paper strips into their correct categories in the table on the illustration board provided.

13. These are handheld instruments that aids in accomplishing a task. In technical drafting, it is typically used to perform accurate or precise dimensions . It can also be termed as reusable for it can be used repeatedly on different drafting projects. DRAFTING TOOLS

14. DRAWING PENCIL One of the most important tools in drawing. The three pencil grades are as follows: Hard pencils – These are used where extreme accuracy is required especially working on graphs, diagrams and charts. Medium pencils – These are used for general purpose work in drawing. Soft pencils – are too soft to be used in mechanical drafting. They are very useful for art work of various kinds.

15. TRIANGLES A three-sided ruler, which typically has two equal sides meeting at a 90 degree angle and to a third side at 45, 30, including 60 degree angles . Typically used in drawing vertical lines and oblique lines. The two types of triangle are as follows: 30 degrees X 60 degrees 45 degrees X 45 degrees

16. T-SQUARE A drawing instrument used when making horizontal lines as well as guiding triangles when drawing vertical lines . There are three (3) types of T-square, namely: Fixed-Head Movable Head or Adjustable Head Detachable Head or Removable Head

17. TRIANGULAR SCALE Generally used when reproducing a drawing in an enlarged or reduced form to some regular proportion . Its main function is to reproduce the measurements of an object in full size, reduced size , and enlarged size .

18. ERASING SHIELD Made up of a plate with irregular holes. A useful tool to protect the rest of the drawing when clearing up smudges, unnecessary pencil lines and other erasures .

19. COMPASS Used when drawing regular curves such as arcs and circles. Composed of one with the pen leg and the needle point leg being held together with a handle. Can be used for both penciling and inking.

20. DIVIDER Used when transferring measurements, dividing lines and arcs into the desired number or equal parts . Can easily transfer accurate measurements by adjusting the divider points .

21. PROTRACTOR A semi-circular instrument divided into 180 equal parts, each of which is called a degree . Used for measuring and setting of angles other than those obtainable with the triangles .

22. PENCIL SHARPENER Used in sharpening pencils whenever they show signs of dullness. It is recommended that a pencil sharpener is sharp enough to create a pointed tip without damaging the pencil. Some of the pencil sharpener’s frame is made of plastic, while some are made of metal.

23. These are used by the draftsman for drawing and designing purposes. Are significantly bigger and need a wider space to manipulate and do drafting activities. DRAFTING EQUIPMENT

24. DRAFTING TABLE A drafting equipment where the drawing paper is being attached on its flat surface to do the drafting works. The board of a drawing table is positioned at an angle of considerable degree which will make the draftsman comfortable in doing his drafting jobs .

25. COMPUTER Are very essential equipment to create, modify, analyze, or optimize drawings through Computer-aided design ( CAD) CAD is a very powerful software for technical drawing. This is used to accumulate the draftsman’s productivity, improve the quality of the design, produce a database for manufacturing and improve communications through documentation.

26. Are things that are said to be consumables . Should be used once, then replace by another, once it was already been used . DRAFTING MATERIALS

27. DRAWING PAPER Is where the draftsman works on his output. Various type of drawing papers are available for use but hand and soft surface drawing papers are recommended to be the best.

28. MASKING TAPE A paper type of adhesive tape . Used for fastening the corners of the drawing paper on the slanting drawing board. Is preferred to use because it does not damage the board and it will not damage the paper when it is detached by pulling it off.

29. SOFT ERASER Is used to clean the dirt off the drawing, erase unnecessary lines and enable corrections . Is advantageous in removing smudges and pencil marks. A gentle pressure on the drawing paper should be observed while using the eraser.

30. “HELP ME IF YOU CAN” The teacher will present situations where each character faces a specific problem. Help each character by telling them the correct tool, equipment, and material to use in each situation.

31. SITUATION 1: 1. Chaewon's drafting paper keeps on falling on the floor. She's been repeating her output for hours because it gets dirty every time it slides from her drawing table. What drafting material does Chaewon need to secure her drafting paper? a. double-sided tape b. masking tape c. duct tape

32. SITUATION 2: 2. Wonyoung is almost done with her artwork. She just needs to draw a perfect circle. What drafting tool can you suggest for Wonyoung to use? a. coin b. compass c. divider

33. SITUATION 3: 3. The members of BTS are filming for a variety show. They are making drawings to give to their fans. However, Jimin keeps on erasing some parts of his drawing unintentionally. What drafting tool should he use to protect the rest of the drawing when clearing up smudges? a. gloves b. plastic cover c. erasing shield

34. SITUATION 4: 4. Yeji loves to draw. However, she doesn't have a specific place to store her tools and materials, so it scatters everywhere. Lia and Ryujin are complaining about Yeji's messy habit. What drafting equipment will you recommend to Yeji ? a. desk organizer b. drawing table c. wooden cabinet

35. SITUATION 5: 5. Hyunjin plans to make a draft of his dream house. He only has whiteboard markers, but it is too thick and dark. What drafting tool is needed so Hyunjin can finally start outlining his dream house? a. drawing pencil b. eyebrow pencil c. colored pencil

36. “BUILD A BEACH HOUSE” Each group will receive tools and materials. The group will design a draft of their ideal beach house using the tools and materials provided. They will present their output and explain how they use the tools and materials.
