Labsheet 3.2 Lines of Symmetry
Measure Drill
Protractor Drill
OBJECTIVE: To recognize similar figures and to be able to tell why they are similar [1.3.3][1.3.1] To understand that any two similar figures are related by a scale factor, which is the ratio of their corresponding sizes To build a larger, similar shape from copies of a basic shape (a rep-tile) To find rep-tiles by dividing a large shape into smaller, similar shapes To understand that the sides and perimeters of similar figures grow by a scale factor and that the areas grow by the square of the scale factor[1.2.1][1.2.3] To find a missing measurement in a pair of similar figures To recognize that triangles with equal corresponding angles are similar above. ACTIVITIES/ASSESSMENT: Measure Drill. Protractor Drill. Labsheet 3.2 will be used with a MIRA to find the lines of symmetry. NOTES: HOMEWORK: P37 #15 a-e

Scale Factor/Symmetry Exercise
OBJECTIVE: See 2-7 above. ACTIVITIES/ASSESSMENT: Measure Drill. Protractor Drill. Draw (not sketch) a scalene triangle#1. label and measure the angles with a protractor, label and measure the sides with a ruler. Make a table to enter the data for 3 triangles. Draw and measure a similar triangle#2 with a scale factor of 2. Draw and measure a similar triangle#3 with a scale factor of 0.5. Explain how the area of triangle#1 relates to the area of triangle#2. Explain how the area of Triangle#3 relates to the area of triangle#2. How does the scale factor relate to the area? Use a picture to demonstrate. NOTES: HOMEWORK: P40 1-4

Problem 4.1 Modified
OBJECTIVE: To use the definition of similarity to recognize when figures are similar To determine the scale factor between similar figures to find the lengths of corresponding sides[1.1.4] To find a missing measurement in a pair of similar figures[1.1.4] To use the relationship between scale factor and area to find the area of a figure that is similar to a figure of a known area[3.2.1] To solve problems that involve scaling up and down[1.1.4] ACTIVITIES/ASSESSMENT: Measure Drill. Protractor Drill. Read page 41. Use the textbook in various locations to determine dimensions. Teacher will pace books; students will determine relative dimensions from their seats using the text size as a reference. [estimating] NOTES: HOMEWORK: P47 1&2
