7-1: Customary Units of Measurement IWBAT convert one unit of customary measurement to another.

Customary Units Length 1 foot (ft) = 12 inches (in) 1 yard (yd) = 36 inches1 yard = 3 feet1 mile (mi) = 5,280 feet1 mile = 1,760 yards Weight 1 pound (lb) = 16 ounces 1 ton (T) = 2,000 pounds Capacity 1 cup (c) = 8 fluid ounces (fl oz) 1 pint (pt) = 2 cups1 quart (qt) = 2 pints1 gallon (gal) = 4 quarts

Examples 1) 36 ft = ____ yd Going from feet to yards, you divide by 3 12 36 ft = 12 yd 2) 36 ft = _____ in Going from feet to inches, you multiply by 12 432 36 ft = 432 in

3) 20 oz = _______ lb Going from ounces to pounds, you divide by16 Going from quarts to pints, you multiply by 2 43

5) 9 yd 2 ft = _____ in Convert yards to inches, then feet to inches. Add. 324 24 324 + 24 348 9 yd 2 ft = 348 in Going from tons to pounds, you multiply by 2000 2500

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 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)

Types of Angles

Classify the Angle

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.

Finding angle measures using angle relationships  Choose the right relationship that will work with the angle measure you’re looking for.  Vertical angles  Straight lines  Corners

7-7: Triangles IWBAT classify and draw triangles, and find missing angles in triangles.

Triangles Classification

Finding Missing Angles

Drawing Angles  Use your protractor!  Use a ruler!

Finding Missing Angles

7-9: Make a Table IWBAT make a table to solve a problem.

7-10: Transformations IWBAT identify translations, rotations, and reflections of two-dimensional figures.

Translation, Rotation, and Reflection Translation (slide) Rotation (Turn) Reflection (mirror)

Line Symmetry

7-11: Using Time Zones IWBAT use logical reasoning to solve problems involving time zones.
