1. -HW P23 #6....
2. =Prob 2.1........
3. =Prob 2.2........
4. =Prob 2.3........
*Problem 2.1 through 2.3 have been allowed class time for their completion and correction. There is no academic reason they are not to be finished.
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 (per side) #To compare lengths and angles in similar and non-similar figures informally #To experiment with examples and counterexamples of similar shapes. ACTIVITIES: Copy the measure drill problem as needed and solve as an additional homework requirement. Finish/Collect 2.1, 2.2 and 2.3 NOTES: HOMEWORK: Explain the following rules about the coordinates (x,y) of any shape: (nx, ny); (x±a, y±b); (nx±a, ny±b)[In other words, what happens to the plotted picture when the rule is applied]

1. =HW MeasureDrill.
2. -HW Trans Rules..OBJECTIVE: See 2-10 above ACTIVITIES:Copy the measure drill as needed. Apply the rules discussed in the homework assignment and the previous Investigation #2 lessons to the set of four pictures. Be sure to indicate/clarify the use of the term SCALE FACTOR (see the listed directions below or in-class) NOTES: HOMEWORK: Start on P27 - Rough draft of answers
2-12-2003
- 1. Record the coordinates for the selected figure in the first column
- 2. Apply the rule and recalculate the new coordinates
- 3. Plot the new figure
- 4. Repeat for the other rules
- 5. Repeat for the other figures
- (Note: Rules may vary from figure to figure, students may need to devise their own rules.)
1. =HW MeasureDrill.
2. =P27 RoughDraft..OBJECTIVE: See 2-10 above ACTIVITIES: Copy the measure drill as needed. Distribute Progress Report #9 Students will complete the translations assigned above. NOTES: HOMEWORK: complete assignments

2. =HW MeasureDrill.
3. -Finish Translations*....
4. -Translation TEST......
*translations means moving an object on a coordinate grid. Used here, it includes enlargements also.
OBJECTIVE: See 2-10 above. ACTIVITIES: Copy the measure drill as needed. Test on translations and rules. NOTES: HOMEWORK: P23 #6

1. =HW MeasureDrill.
2. -Measure Final...
3. -HW P23 #6.......OBJECTIVE: #To recognize similar figures and to be able to tell why they are similar #To understand that any two similar figures are related by a scale factor, which is the ratio of their corresponding size #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 #To find a missing measurement in a pair of similar figures #To recognize that triangles with equal corresponding angles are similar ACTIVITIES: Measure drills final. Students who do not pass will have a note inserted into their file. Page 28, Patterns of similar figures, Lesson 3.1 Identifying similar figures. NOTES: HOMEWORK: From your notes - Define Scale Factor, Give an example. This will be a journal entry.
