tables and graphs that show
relationships between
variables, each with their
own advantages and
disadvantages.
.

Similarity Transformations
When shapes shrink or
grow, what changes and
what stays the same?
KEY CONCEPTS
FOCUS AND CONTENT
SKILLS
Key 1: Certain attributes change
and certain attributes stay
the same when you perform
transformations on figures
and for similarity
transformations, those
attributes have a
commonality
 Identify similar figures by
comparing corresponding parts

Key 2: Some algebraic rules can
describe similarity
transformations and some do
not, and the looking at the
rule can help us identify what
kind of tranformation is
produced by it.
Key 3: The magnitudes of similarity
transformations can be
expressed by the scale
factor which can be used in
solving problems that involve
finding missing sides and the
area of similar figures.
 Use scale factors and ratios to
describe relationships among
the side lengths of similar
figures.
 Construct similar polygons.
 Draw shapes on coordinate
grids and then use coordinate
rules to stretch and shrink those
shapes.
 Predict the ways that stretching
or shrinking a figure affect
lengths, angle measures,
perimeters, and areas.
 Use the properties of similarity
to calculate distances and
heights that can't be directly
measured.
Key 4: Scale factor can be used
with similar figures to find
missing measures of parts

7th Grade Math – Road Map (2009-2010)
Ratios, percents, fraction,
differences, and scaling can
be used to compare values
and using multiplicative or
divisive models can provide
more information about a
situation than that obtained
from using a subtractive
model.
Ratios can be compared
using equivalent ratios,
percents, and fractions, and
those comparisons can be
used to choose between
options in problems
concerning situations where
two quantities vary and the
relationship between those
quantities is important.
Unit rates are a powerful
tool for expressing the
relationship between related
quantities and they simplify
comparison and problem
solving.
Equivalent ratios, or
proportions can be used to
find missing measures in
similar figures and to solve
problems involving
situations where the ratio
between two quantities
needs to stay constant.

CMP 2:
Moving Straight Ahead
PH Course 2:
Pages 434 - 504
PACING
Suggested Pacing: 28 days
March 11 – April 28, 2010
KEY CONCEPTS
Key 1: Linear functions can be
identified by properties
of their graphs, tables,
equations and contexts;
these properties can be
used to distinguish
linear from other types
of functions.
Key 2: Linear functions are
distinguished by the fact
that a change in the
independent variable
results in a constant,
predictable change in
the dependent variable.
Key 3: Pairs of values that can
be substituted in two or
more equations to make
them true are called
solutions, and can be
found using tables,
graphs and symbolically.
Key 4: Slope is the ratio of
vertical change to the
horizontal change
between two points on a
line, the coefficient of
the independent
variable in an equation,
and the rate of change
in the dependent
variable in a table when
the independent
variable changes by
one, and it represents a
unit rate connecting the
variables that are in the
linear relationship .

cylinders are equal to the
product of the area of their
