  1. Standard: MCC6.RP.3d Use ratio reasoning to convert measurement units, manipulate and transform units appropriately when multiplying or dividing quantities.

  2. What are the metric measurements that we are learning about? • Meter Length • Liter Volume • Gram Weight or Mass

  3. How to remember different lengths in the metric system: • When you think of a millimeter (mm) think of: • The thickness of a dime. • When you think of a centimeter (cm) think of: • The width of your pinky.

  4. How to remember different lengths in the metric system: • When you think of a meter (m) think of: The height of the doorknob. When you think of a kilometer (km) think of: A little more than half of a mile

  5. How to remember different volumes in the metric system: • When you think of a liter (L) think of: About the size of a bottle of water. • When you think of 5 milliliters (mL) think of: One teaspoon • When you think of 2 kiloliters (kL) think of: A hot tub

  6. How to remember different masses in the metric system: • When you think of a gram (g) think of: A paper clip • When you think of a kilogram (kg) think of: A little more than 2 pounds.

  7. What is the order of the metric system? • King Henry Died by Drinking Chocolate Milk • King: Kilo • Henry: Hecto • Died: Deca • By: Base (m, L, g) • Drinking: Deci • Chocolate: Centi • Milk: Milli

  8. Metric System • If you move to the leftin the diagram, move the decimal to the left • If you move to the right in the diagram, move the decimal to the right

  9. Metric System An easy way to move within the metric system is by moving the decimal point one place for each “step” desired Example: change meters to centimeters 1 meter = 100 centimeters or 1.00 meter = 100. centimeters

  10. Metric System • Now let’s try our previous example from meters to kilometers: 16093 meters = 16.093 kilometers • So for every “step” from the base unit to kilo, we moved the decimal 1 place to the left (the same direction as in the diagram below)

  11. Metric System Now let’s start from centimeters and convert to kilometers 400000 centimeters = 4 kilometers 400000 centimeters = 4.00000 kilometers

  12. Metric System • Now let’s start from meters and convert to kilometers 4000 meters = 4 kilometers • Now let’s start from centimeters and convert to meters • 4000 centimeters = 40 meters

  13. Metric System Now let’s start from meters and convert to centimeters 5 meters = 500 centimeters • Now let’s start from kilometers and convert to meters • 0.3 kilometers = 300 meters

  14. Metric System Now let’s start from kilometers and convert to millimeters 4 kilometers = 4000000 millimeters or 4 kilometers = 40 hectometers = 400 decameters = 4000 meters = 40000 decimeters = 400000 centimeters = 4000000 millimeters

  15. Metric System • Summary • Base units in the metric system are meter, liter, gram • Metric system is based on powers of 10 • For conversions within the metric system, each “step” is 1 decimal place to the right or left • Using the diagram below, converting to the right, moves the decimal to the right and vice versa
