1. Question of the day
What is the scale factor of yards to inches?

2. Learning goal
Students will be able to compare, contrast, and convert units of measure between different measurement systems (US customary or metric SI), dimensions, and derived units to solve problems.

3. Level 2
Students will:
Identify the appropriate unit of measure for the given object
Identify units (length, mass or capacity/volume)
Identify what is Customary and Metric
Define key terms.

4. Level 3
Students will:
Use dimensional analysis to solve problems within same measurement system (Metric or Customary)
Convert between Metric and Customary

5. Level 4
Use dimensional analysis between systems to solve real-world problems
Create a word problem involving dimensional analysis between two systems

6. Key terms Metric system US customary system Volume Mass
Unit of measure
Conversion factor

7. Measurements conversion
US customary and Metric systems

8. US customary units

9. Choose the appropriate customary unit

10. You try The weight of a car? Length of a piece of paper?
How much water in a small pool?

11. Finding conversion factor
This is the difference between two units of measure.
Example from inches to feet it would be 12 1

12. You try
Conversion factor
Cups to pints
Ounces to pounds

13. Converting customary units
1. find the conversion factor between the two you are converting
2. Create a proportion between the conversion factor and given information
3. Cross, cross, divide (sing the song if needed)

14. example
Convert 18 cups to pints.
𝑐𝑢𝑝𝑠 𝑝𝑖𝑛𝑡𝑠 = 18 𝑋

15. You try
Convert 30 inches to feet
Convert 1500 lbs. to tons

16. Sometimes you will have to do more than one conversion.
Example it you are converting from inches to miles.
Just do one conversion at a time until you reach the correct ending unit

17. Metric unit of measures
Grams
Measurement of mass or weight
Liter
Measurement of volume or capacity
Meter
Measurement of length

18. Metric units of measure prefixes

19. Metric system units

20. Choose appropriate metric unit
The weight of a car?
Length of a piece of paper?
How much water in a small pool?

21. Converting between units of Metric
Because the metric system is based on units of ten, we do not need scale factors.
We only need to know how many times we will be diving or multiplying by ten

22. Example
Example if we are converting between Kilo- and Deca-, that is two steps .
two steps of 10 equal 100, so we multiply 100

23. example
Covert 4 kilometers to meters
That is 3 jumps
Each jump is 10, so three would be 1000
10 x 10 x 10 = 1000
4 x 1000= 4000

24. You try Convert 20 milligrams to decigrams
Convert 34 hectograms to grams

25. summary
Describe in words how you would convert inches to miles
