Name: Period: Date: SCALE DRAWING PROJECT Goal: You will select a cartoon carton or picture and use scale factor to enlarge it to best fit a sheet of paper or half poster. Include in your project: 1. 2. 3. 4. 5. The original picture The enlarged picture (colored to match original) Measurements of the original picture The scale selected to enlarge the picture Self-Completed Evaluation Illustration: Step 1: Measure the length and width of the cartoon character in cm. (It does not matter which side you label the length and width; be consistent with your sides on the large paper) (Lc) Length __________ (Wc) Width ____________ Step 2: Tape your picture on the centimeter grid paper that is provided. Draw a square grid over your picture with a color pen. Be very precise and make sure that all lines are equally spaced. Number the rows and columns so that the boxes have reference. [10pts] Step 3: Measure the paper in cm. (Lp)Length __________ (Wp)Width ____________ Step 4: Select a scale (1 cm on pictures = __________ cm on paper) Scale factor model:original. To do this find the ratio of lengths and widths i.e.: Lp Lc = = _______ Wp Wc = = _________ Then pick the smallest of the two numbers and round down to the nearest whole number (i.e. if you get 4.29 and 4.76 your scale should be 1 cm wrapper = 4 cm on paper) Step 5: Draw the borders Multiply your length and width of the cartoon character by your scale factor and see how much of the paper you have left over for the border. Take the new length of your picture and subtract it from the paper length, then divide it by two, this will tell you how far the border will be away from the edge of your paper. i.e. L C x Scale Factor = _____ Lp – L C = _________ Then ÷ 2 _____ WC x Scale Factor = _____ Wp – WN = __________ Then ÷ 2 ______ SCALE DRAWING PROJECT Name: Period: Date: PROJECT IS DUE BY JUNE 06 OBJECTIVE: To enlarge small picture to poster size your using grid scaleon drawing Draw your border around youra paper before drawing your techniques. paper.

The reflection has to be a paragraph and expressed for your drawing. You will be graded according to the grading rubric located on the answering some of the following questions: The rubric must be turned in with your finished product. HAVE FUN!

Name: Period: Date: SCALE DRAWING PROJECT Rubric: NOTE: When you submit your project, you will first score yourself using this rubric. Be honest and thorough in your evaluation. Remember to include the following parts in your presentation: Include in your project: 1. 2. 3. 4. 5. The original picture The enlarged picture (colored to match original) Measurements of the original picture (front page) Reflection (may be typed or neatly hand-written) Self-Completed Evaluation (this form) 5 Scale Grids Presentation Reconstruction Reflection All calculations and proportions are shown and done correctly All grid lines can be seen on drawing and match the original picture. Clearly measured correctly and scaled properly. The enlarged picture is colored neatly in the lines and colors match original wrapper. All proportions are accurate on the enlarged picture. Reflection is neatly written with no errors and clearly communicates details about scale factor using academic vocabulary. 3 1 Some calculations are missing or are incorrect. Grid lines may not match wrapper but are parallel and show some understanding of scale factor. Some of the enlarged picture is colored neatly in the lines and some of the colors match original comic. Some proportions are not accurate on the enlarged picture Reflection is not wellwritten may contain errors and poorly communicates details about scale factor, but uses some academic vocabulary. No calculations and proportions are shown or all are incorrect No lines are parallel, or measured correctly. The scale does not in any way match the calculations. The enlarged picture is not colored neatly in the lines and does not match original wrapper. No proportions are accurate on the enlarged picture Reflection is poorly written with multiple errors and does not communicate details about scale factor. Uses no academic vocabulary.
