Projections Examples
Start Page 20 Problem 2.2
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: Pages 18-20 Problem 2.2 'Nosing around' NOTES: Need more projection practice. HOMEWORK: Redo Page 13 - Modified directions.Change the statement in #1 to read 'Measure this rectangle and draw one twice as big.' Answer questions 1a, 1b, and 1c.

Create Similar Objects
OBJECTIVE: See 1-24 above. ACTIVITIES/ASSESSMENT: Draw (with a ruler) a triangle. Measure and label the angles with a protractor. Create a new triangle with a scale factor of 2. Measure and label the new angles. Measure the sides. Are the angles congruent? Are the sides proportional? Repeat with a quadrilateral that is not a square or rectangle. Use a scale factor of 0.5. List data in a table. NOTES: similarmake.doc angseg.gif HOMEWORK: P23 #6&7

Space Bunny
OBJECTIVE: See 1-24 above. ACTIVITIES/ASSESSMENT: Warm-Up decimal multiplication (provide an introduction - no calculators. Working with space bunny ( (2,1), (5,3), (2,4), (3,3), (1,3)) make tables and implement the following rules 1)2x,2y 2)x+8,y 3)x+3 y+7 4)0.5x,0.5y Reflect original figure across the x axis. NOTES: Model the table on the board. 1st and 4th quadrant only. Present questions on scale factor. HOMEWORK: P26 #14; P27 1&2

Vocabulary Quiz
OBJECTIVE: See 1-24 above. ACTIVITIES/ASSESSMENT: Write a paragraph with 10 of the vocab terms (selected) in a manner which shows understanding. Model on the board. Underline in final copy. NOTES: HOMEWORK: P24 #9
1-28-2005Example: 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.

Start Page 28 Problem 3.1
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: Start on problem 3.1 (worksheet) by measuring all of the sides and angles with protracotrs - model the need to extend lines to measure the angles. NOTES: HOMEWORK: None - end of the quarter.
