3. Scale Drawing - Room

OBJECTIVE: 1.1.4 Understand the concept of direct proportion. 1.3.1 Understand the concept of similarity and its relationship to congruence. 1.3.3 Describe the location of points on a coordinate grid in any of the four quadrants. 1.3.4 Apply a combination of translations and/or reflections to 2 dimensional figures. ACTIVITIES/ASSESSMENT: Students will complete a scale drawing of the room they brought dimensions of - all students will be assigned a fixed base line for the longest wall. Calculations will have to be shown using scale factors and/or proportions. NOTES: Emphasize the relationship between scale factor and proportion. Stress that it is linear. HOMEWORK: Page 54 16-19
