Where are you going?
UNKNOWN information
What units should the answer be in?
How to I get there?
Do I need to find a number/value first before I continue?
When all else fails, draw it.

5. CALCULATE Execute the plan Do I need to re-arrange an equation first
Plug and Chug

6. EVALUATE Is the answer reasonable?
Is it near the values I should expect?
Did I fully answer the entire question?
Do I have the right units?
Do I have the right amount of significant figures? (Will go over in later chapters)
