1. “I can state the appropriate measure and degree of accuracy.”

2. What will you be doing?  You will be learning about units of measurement for Length, Weight, Capacity/Volume, and Time.  You will need to know what kind of units you can measure with.  You will also need to choose the best unit of measure and explain why it is the best.

3. Units of Measure  Units of measure are the names of measurement we use when we measure.  Ex: 1 inch, 1 foot, 1 mile = 1 unit of measure for length.  There are lots of different units to choose from and some tools use more than 1.

4. How to Measure  When we measure, we need to 1 st choose the units that go with what we are measuring.  Then we need to choose the most appropriate type of unit for that measurement.

5. How to Measure  Choose the right units for length, weight, capacity/volume, or time. Ex: You don’t measure weight with hours!  Choose the unit that makes sense. Ex: You don’t measure your height in miles! Ex: It would take you weeks to measure a swimming pool with a teaspoon!  Measurements shouldn’t be in decimals nor should they be gigantic numbers!

6. Types of Measurement Types of units for a measure Metric & U.S. Custom units Unit equivalents (something that is almost the same as the unit in real life or could be used to measure with).

7. How to write this all down-  The left side of the page will be about Metric, the right side will be about U.S. Custom.  Save room between each word so that you can write an equivalent object of measure.

8. Length Metric  Millimeter  Centimeter  Meter  Kilometer U.S. Custom  Inch  Foot  Yard  Mile

9. Metric Lengths  Millimeter (mm) Thickness of credit card. 1/1000 m  Centimeter (cm) Thickness of a finger. 1/100 m  Meter (m) Length of a baseball bat.  Kilometer (km) Length of a city block. 1000 m

10. U.S. Custom Length  Inch (in) Length of the last part of your thumb. 12in = 1ft  Foot (ft) Length of textbook. 1ft = 12in  Yard (yd) Length of baseball bat. 1yd = 3ft  Mile (mi) Length of city block. 1mi = 1,760yd

11. Weight Metric  Grams  Kilograms U.S. Custom  Ounces  Pounds  Tons

12. Metric Weights  Gram (g) Weight of a paperclip. 1000g = 1kg  Kilogram (kg) Weight of a textbook. 1kg=1000g

13. U.S. Custom Weight  Ounce (oz) Weight of a slice of bread. 16oz = 1lb  Pound (lb) Weight of a can of soup. 1lb = 16oz  Ton Weight of a small car. 1ton = 2000lb

14. Capacity / Volume Metric  Milliliter  Liter U.S. Custom  Fluid Ounce (fl oz)  Cup (c)  Pint  Quart  Gallon

15. Metric Capacities / Volumes  Milliliter (ml) Almost 20 drops of water. 1000ml = 1l  Liter (L) Medium soda bottle. 1L=1000ml

16. U.S. Custom Capacity / Volume  Fluid Ounce (fl oz) Medicine cup. 8fl oz = 1cup  Cup School milk. 2cup = 1pint  Pint Large drink. 2pint = 1 quart  Quart (qt) Large glass measuring container. 4qt = 1g  Gallon (gal) Large milk jug.

17. Time  Seconds  Minutes  Hours  Days  Weeks  Months  Years

18. That’s all there is to write…  Now you need to: Start measuring Choose units to measure with Decide which units work best Explain why some units are better than others for certain measurement jobs Use this as a reference if you forgot something!

19. 1 Last Note!  Think about what you need to measure-  Is it very tiny, small, large, or huge ?  This will make a difference about what unit to choose. Your measurements shouldn’t be in decimals nor should they be gigantic numbers!
