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 Moves down 2, move decimal to the right twice. 2.05 m = 205 cm 3) 4 kg = ______ g Moves down 3, move decimal to the right three times. 4 kg = 4,000 g
Examples 1) 30 kL = ____ L 30 kL = 30,000 L 2) ____ kL = 4,250 L 4.25 kL = 4,250 L 3) ____ dm = 1 m 10 dm = 1 m 4) 2,500 mm= ____ m 2,500 mm = 2.5 m
7-3: Converting Between Measurement Systems IWBAT convert units between the customary and metric systems of measurement.
Customary and Metric Unit Equivalents LengthWeight and MassCapacity
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)
Drawing Angles Use a protractor 1. Identify the type of angle 2. Use protractor to draw straight lines and to measure degrees. a) Depending on the type of angle, you will use a specific side of the protractor 3. 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.
