OBJECTIVE: Investigation 3: #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 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: Finish Virus model. Additional Practice 3

OBJECTIVE: Investigation 4: #To use the definition of
similarity to recognize when figures are similar. #To
determine the scale factor between two similar figures. #To
use the scale factor between similar figures to find the length
of corresponding sides. #To find a missing measurement in a
pair of similar figures. #To use the relationship between
scale factor and the area to find the area of a figure that is
similar to a figure of a know area. #To solve problems that
involve scaling up and down. ACTIVITIES: Cooperative exercise,
complete Investigation 4. NOTES: HOMEWORK: Make a SKETCH of a
birds eye view of your bedroom or personal area showing the
location of doors and windows (NOT furniture). The sketch is to
fit on a sheet of notebook paper. Measure walls, windows, doors, etc. to the nearest ½
inch or centimeter.
