4. Central Question ‹#› What is the role of ICT illustration in today’s society and the Philippine economy?

5. ‹#› Perform Mensuration and Calculation Lesson 4

6. At the end of this lesson, the learners should be able to do the following: Identify different instruments used in illustration. Select appropriate measuring tools based on job requirements. Perform mensuration and calculation through four fundamental mathematical operations (addition, subtraction, multiplication, and division). ‹#› Learning Targets

7. ‹#› Let Us Measure and Draw! Recharge

8. ‹#› Instructions Note that this is an individual activity. Look at the figure on board. Copy the figure on your paper. Make your own measurements of the figure using a ruler. I ndicate your unit of measurement . Prepare to share your work with the class.

9. ‹#›

10. ‹#› Activity Processing The appropriate measuring instrument depends on the task and the parts to be measured. Recharge

11. ‹#› Identifying Appropriate Measuring Instrument in Illustration The appropriate measuring instrument depends on the task and the parts to be measured, and we must consider the following factors: size of parts to be measured skills of the operator cost of equipment

12. ‹#› Identifying Appropriate Measuring Instrument in Illustration Size of parts to be measured – It determines the length of the object to be measured. For example, how long the object is, how tall, or how far apart in terms of distance. Use the appropriate measuring device based on the size of the object to be measured.

13. ‹#› Identifying Appropriate Measuring Instrument in Illustration Skills of the operator – The operator must have the knowledge and skills to use the measuring instruments in carrying out tasks. Without such skills, this may damage the measuring tools and the object being measured or might cause harm to the operator.

14. ‹#› Identifying Appropriate Measuring Instrument in Illustration Cost of equipment – Consider the quality of the brand of the measuring instrument. Evaluate the cost of the measuring instrument by associating its function and its maintenance.

15. ‹#› Identifying Appropriate Measuring Instrument in Illustration r uler – for measuring a straight line, for drawing, or cutting T square – for drawing horizontal lines s cale ruler – primarily for drawing architectural, structural, and mechanical details

16. ‹#› Identifying Appropriate Measuring Instrument in Illustration triangle rulers – to draw vertical lines and different angles compass – for small circles and arcs; with an adaptor or ink attachment French curve – for irregular curves in contour lines

17. ‹#› Identifying Appropriate Measuring Instrument in Illustration protractor – to measure angles that can be either circular or semicircular templates – for circles, ellipses, lettering, flowcharting, mechanical, and much more

18. ‹#› Importance of Measuring Instruments Without measurement systems, it will be difficult for us to conduct experiments and form scientific theories. Bad equipment or human error can lead to inaccurate results. For instance, in a mass production process, everyone must be consistent in using the same terminologies about the measuring instruments to create a harmonious style of the final output.

19. ‹#› Identifying Correct Specifications for Measuring Instruments Amplification This is also called magnification or the ratio of the input and output dimension of the measuring instrument. Calibration This is the process of adjusting a measuring instrument to its standard measurement. Stability The capability of measuring instruments to maintain their calibration over time .

20. ‹#› Identifying Correct Specifications for Measuring Instruments Accuracy It is the amount of uncertainty with respect to standard measurement, and it is the true magnitude of the measured dimension. Precision It describes the consistency of the measurement or the degree of reliability standard of a measuring instrument. Resolution It is the process of separating a measurement into parts, and it is the smallest magnitude from the measured value that can be distinguished by an instrument.

21. ‹#› Identifying Correct Specifications for Measuring Instruments Sensitivity It can be defined as the smallest amount of change that can be detected by a measuring instrument. Copying For beginners, copying the exact matter of the drawing is one of the best methods to start measuring without any instrument. Copying also gives training to the eye to correct mistakes in the estimates of lengths .

22. ‹#› Eye Measurements with Rule of Thirds In order to practice measuring by eye, try these steps: By just looking at an object, imagine three vertical lines. Draw another line and divide it into thirds horizontally. Measure the length of each segment after you divide it by the eye. Practice this until you come close to the particular part of an object.

23. ‹#› Eye Measurements with Rule of Thirds

24. ‹#› Identifying Correct Specifications for Measuring Instruments Proportion A proportion is an equation with a ratio on each side. It states that two ratios are equal. For example, 1/2 = 4/8. It is also described as a part, share, or number in comparative relation to a whole that can be written in two ways: two equal fractions a = c b d or using a colon a:b = c:d This simply states that two ratios are equal. In math: 2 = 4 3 6

25. ‹#› Measuring through a Pencil Choose how far away from your subject you will stand. Mark the length, width, or height of the object with your thumb on the pencil. Transfer this measurement to the drawing. When drawing a house, put your thumb on the pencil at the point where you can trace the length of the house. Do this as a standard for other relative measurements.

26. ‹#› Instructions Get your tools for the activity (bond paper, ruler, pencil, triangle, compass, and protractor). Draw the following on your bond paper: five vertical lines using the ruler (3 inches long) horizontal lines using the ruler (10 centimeters long) angles in 30 degrees, 45 degrees, and 90 degrees using the protractor two circles, two concentric circles, and two half circles using the compass Prepare to share your work with the class. Enlighten

27. ‹#› Activity Processing Enlighten To practice measurement and proportion skills, we need to vary the scale of drawings by repeating the same drawing at different sizes .

28. ‹#› Mensuration and Calculation Mensuration deals with the length, area, and volume of different kinds of shapes: both 2D and 3D. Area (A) I t is the surface occupied by a given closed shape. Perimeter (P) It is the length of the boundary of a figure. Volume (V) It is the space contained in a three-dimensional shape.

29. ‹#› Mensuration Formulas Mensuration is the branch of mathematics that deals with the study of geometric shapes, their area, volume, and related parameters. Square: Area = a2 sq. units Perimeter = 4a units Rectangle: Area = l x sq. units Perimeter = 2(l+b) units Cube: Volume: a3 Triangle: Area = √3a2 /4 sq. units Perimeter = 3a units (a = side of the triangle)

30. ‹#› Mensuration Formulas Circle: Diameter = 2r units Area = ℼr2 sq. units Circumference = 2ℼr units Solving Mathematical Problems with PEMDAS P – parentheses E – exponents M – multiplication D – division A – addition S – subtracti o n Cylinder: Volume= ℼr2h

31. ‹#› Instructions Note that this is an individual activity. Read the questions carefully. Answer all problems using the formulas discussed, and show your solution. Prepare to share your answers with the class. Enlighten

32. ‹#› Enlighten Problems: We learned that mensuration deals with the length, area, and volume of different kinds of shapes. Write the formula for the following: area of a triangle diameter of a circle perimeter of a rectangle What is the circumference of a circle if the radius is 5? Show your solution. What is the perimeter of a rectangle if the length is 30 inches and the width is 10 inches? Show your solution. What is the area of a circle if the radius is 8? Show your solution. Solve the following equation using the PEMDAS method: -2 × (-3 × 2)2 – (-2)2

33. ‹#› Activity Processing Enlighten Mensuration plays a big part in real-world applications in illustration industry.

34. ‹#› Logo Design Reexplore Scenario: You are assigned as an illustrator in the journalism club. Your task is to make a creative logo for the school newspaper. Apply your learning to measuring tools. Be creative.

35. School Newspaper Logo Design Geometric shapes used: circle, rectangle, triangle, and arc ‹#› Reexplore

36. ‹#› Instructions Note that this is an individual activity. Get the materials needed for the activity. Create your logo design using geometrical shapes. Use measuring tools for accurate measurement. List the shapes you used in your logo. Prepare to share your work with the class. Reexplore

37. ‹#› Activity Processing Measurement leads us to control and improve our abilities. You cannot measure if you do not understand it. If you cannot control it, you cannot improve it. Reexplore
