HOMEWORK: Tranformations - reflect and rotate samples
Space Bunny II
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 ACTIVITIES/ASSESSMENT: Complete the space bunny 2 assignment. On another sheet, practice enlargements and reductions. Discuss Ratio (Show video) NOTES: HOMEWORK: Draw 2 similar triangles with unit sides (no fractions or decimals). Measure the sides. Write the sides as ratios. Model

HOMEWORK: Side Ratios of Triangles
Terms Paragraph
OBJECTIVE: See 1-24 above. ACTIVITIES/ASSESSMENT: Page 31 Problem 3.3 'Subdividing to find rep-tiles' This will be a group project (groups of 4) formed when the paper is done. Students will cut out the shapes and assemble into appropriate 'rep-tiles'NOTES: Write a paragraph with 10 of the vocab terms in a manner which shows understanding. Model on the board. Underline in final copy. HOMEWORK: P36 11-14. Area does not have to be determined by formula calculation.
Example: To compare two images means to see how they are alike. If the angles are congruent or identical that is one part of the comparison. If the line segments or sides of the object can all be multiplied by the same number or factor, them the sides are compared.

OBJECTIVE: See 1-24 above. ACTIVITIES/ASSESSMENT: Page 31 Problem 3.2 part 'a' and follow-up 1 and 2. NOTES: Students will work in groups of four with tiles to determine which shapes will repeat in a 'rep-tile' (repeating tile pattern) They are to draw the pattern used on the lab sheet. Each person must have a drawing. Use rulers to be accurate. HOMEWORK: Page 38 18&19
