There are two steps to solving math word problems:
1. Translate the wording into a numeric equation
that combines smaller "expressions"
2. Solve the equation!
* Read the problem entirely
Get a feel for the whole problem
* List information and the variables you identify
Attach units of measure to the variables (gallons, miles, inches, etc.) * Define what answer you need,
as well as its units of measure
* Work in an organized manner
Working clearly will help you think clearly
* Draw and label all graphs and pictures clearly
* Note or explain each step of your process;
this will help you track variables and remember their meanings * Look for the "key" words (above)
