7-2: Metric Units
of
Measurement
IWBAT convert one unit of
metric measurement to
another.
Metric Units
 Based
on powers of 10
 Use as universal measurement of science
 Rest of the world uses this system
Stair Conversion
Using the Stairs
1) 1,600 m = ____ km
Moves up 3, move
decimal to the left three
times.
1,600 m = 1.6 km
2) 2.05 m = _____ cm
3) 4 kg = ______ g
Moves down 2, move
decimal to the right
twice.
Moves down 3, move
decimal to the right
three times.
2.05 m = 205 cm
4 kg = 4,000 g
Examples
1) 30 kL = ____ L
30 kL = 30,000 L
4) 2,500 mm= ____ m
2) ____ kL = 4,250 L
4.25 kL = 4,250 L
3) ____ dm = 1 m
10 dm = 1 m
2,500 mm = 2.5 m

Converting
 Use
proportions in correlation with the
conversion chart
7-4: Spatial
Reasoning
IWBAT use spatial reasoning
to solve problems.
7-5: Classifying
and Measuring
Angles
IWBAT draw, measure, and
classify angles.
Parts of an Angle
 Angles
are made up of two rays (sides)
and one vertex (corner)
 How wide or narrow an angle is, is its
measurement (in degrees)
Types of Angles




Right Angle = Exactly 90°
Obtuse Angle = Greater than 90°, Less than 180°
Acute Angle = Less than 90°, Greater than 0°
Straight Angle = Exactly 180°
Congruent Angels = Angles that have the same
measure
Classify the Angle
Drawing Angles
 Use
1.
2.
Identify the type of angle
Use protractor to draw straight lines and to
measure degrees.
a)
3.
a protractor
Depending on the type of angle, you will
use a specific side of the protractor
Draw arrows at the end of your lines so
that they are rays
Measuring Angles
 Identify

they type of angle
This will determine which side of the
protractor to read from
 Line
up vertex with the central point of the
protractor

You may have to extend the rays to go
beyond the protractor
 Read
the degree measurement on the
protractor
7-6: Angle
Pairs
IWBAT find the measure of
an unknown angle from its
relationship to other angles
Types of Angle Pairs
Vertical Angles – Angles that share a vertex, but
have no sides in common. They are congruent.
Adjacent Angles – Two angles that share a
common side and vertex.
Supplementary Angles – Two angles with the sum of 180°
Complementary Angles – Two angles with the sum of 90°
Finding angle measures using
angle relationships
 Choose
the right relationship that will work
with the angle measure you’re looking for.
