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

2
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

4
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

5
3) 20 oz = _______ lb Going from ounces to pounds, you divide by16 Going from quarts to pints, you multiply by 2 43

6
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
7-2: Metric Units of Measurement IWBAT convert one unit of metric measurement to another.

8
Metric Units Based on powers of 10 Use as universal measurement of science Rest of the world uses this system

9
Stair Conversion

10
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

11
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

12
7-3: Converting Between Measurement Systems IWBAT convert units between the customary and metric systems of measurement.

13
Customary and Metric Unit Equivalents LengthWeight and MassCapacity

14
Converting Use proportions in correlation with the conversion chart

15
7-4: Spatial Reasoning IWBAT use spatial reasoning to solve problems.

16
7-5: Classifying and Measuring Angles IWBAT draw, measure, and classify angles.

17
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)

18
Types of Angles

19
Classify the Angle

20
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

21
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

22
7-6: Angle Pairs IWBAT find the measure of an unknown angle from its relationship to other angles

23
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.

25
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

26
7-7: Triangles IWBAT classify and draw triangles, and find missing angles in triangles.

27
Triangles Classification

29
Finding Missing Angles

30
Drawing Angles Use your protractor! Use a ruler!

31
7-8: Quadrilaterals IWBAT classify and find the missing angles of quadrilaterals.

32
Types of Quadrilaterals

33
Finding Missing Angles

34
7-9: Make a Table IWBAT make a table to solve a problem.

35
7-10: Transformations IWBAT identify translations, rotations, and reflections of two-dimensional figures.

36
Translation, Rotation, and Reflection Translation (slide) Rotation (Turn) Reflection (mirror)

37
Line Symmetry

38
7-11: Using Time Zones IWBAT use logical reasoning to solve problems involving time zones.

39
US Time Zones
