The document discusses converting between metric units of measurement by multiplying or dividing by powers of 10. It provides examples of converting grams to kilograms, milliliters to liters, and meters to kilometers. Students are expected to learn that multiplying converts to a smaller unit and dividing converts to a larger unit. Mnemonic devices are suggested to remember the order of metric units from smallest to largest.
1. Learning Target:Students will learn how to convert from one metric unit of measure to another by multiplying or dividing by a power of 10.
2. Some things to Remember when converting any type of measures:- To convert from a larger to smaller metric unit you always multiply. - To convert from a smaller to larger unit you always divide.
4. For every step upward on the chart you are dividing by 10 or moving the decimal one place to the left..
5. When you move down the stairs you are multiplying by 10 for each step. SO you are adding a zero to your original number and moving the decimal one place to the right with each step.
6. I way I remember the order of metric units is by remembering the saying:“Keep Hands Dry During Cold Months”Base Unit of grams, liters, meters
7. Take 2 minutes and try to come up with a saying that will help you remember the order of the metric units.

10. A library is 25 m long. What is its length in kilometers?A: 2.25 km B. 0.25 kmC: 0.025 km D. 0.0025km
11. A library is 25 m long. What is its length in kilometers?A: 2.25 km B. 0.25 kmC: 0.025 km D. 0.0025km
12. When we were asked to compare two fractions (not unit fractions), what did we have to do in order to prove that the one fraction was truly larger then the other?
13. A: We found a common denominator. We use the same idea when comparing measurements of different units. We need to convert one of the units to the other so they both have the same units.
14. Which is greater 0.24 g or 250 mg?Compare 50 mm and 3.5 cm.Compare 0.01 kg and 8 g
15. Which is greater 0.24 g or 250 mg?A: 250 gCompare 50 mm and 3.5 cm.A: 50 mm > 3.5 cmCompare 0.01 kg and 8 gA: 0.01kg > 8 g
16. A jar filled with dimes has a mass of 2.5 kg. The empty jar’s mass is 0.63 kg. A dime’s mass is about 2.2 g. About how many dimes are in the jar?
17. A jar filled with dimes has a mass of 2.5 kg. The empty jar’s mass is 0.63 kg. A dime’s mass is about 2.2 g. About how many dimes are in the jar?A: about 850 dimes
