Homework: Draw a 5cm x 7cm grid; Draw a 5" x 7" grid

OBJECTIVE: •To describe in an intuitive way what the word similar means [1.3.1 Understand the concept of similarity. * Identify corresponding sides and angles of two similar figures.* Determine and justify if two figures are similar using the definition of similarity. [CU, RL]* Differentiate between similar and congruent figures, either geometric figures or real-world objects, and justify the conclusion. [RL, MC]* Explain how a scale drawing is an example of similarity. [CU]] •To consider relationships between lengths and between angles in simple, similar figures [1.3.3] ACTIVITIES/ASSESSMENT: Start on next section dealing with Stretching and Shrinking (ratio and proportion) This will begin with an introduction to dilations - model the rubber band model from the SAS book. Demonstrate the projection method and if equipment is available demonstrate the pantagraph. NOTES: Collect/Distribute Texts. HOMEWORK: Draw a triangle, use the projection method to make one larger and one smaller. Measure all sides and place dimensions in a table.

=Homework: Page 13 1a,1b.1c

OBJECTIVE: •To review locating points in a coordinate system •To graph figures using algebraic rules •To predict how figures on a coordinate system are affected by a given rule •To learn that corresponding angles of similar figures are equal and that corresponding sides grow by the same factor[1.3.1]•To compare lengths and angles in similar and nonsimilar figures informally •To experiment with examples and counterexamples of similar shapes [1.3.4] Understand and apply combinations of translations (slides) and reflections (flips) to two-dimensional figures. ACTIVITIES/ASSESSMENT:Read from page 14. Do page 16 Problem 2.1 a & b. NOTES: HOMEWORK: P22 #1, P23 #6
