When solving Word Problems, extract and organize information using the GREASERS method:

  • Given (write down what each number in the questions represents)

  • Required (write down what the questions is asking AND what information you need to find it)

  • Estimate (make an upper and lower limit guess that your answer should fit into)

  • Analysis (determine what equations or processes are needed to find the answer)

  • Solve (do the math ... find your answer using your plan)

  • Estimation Review (compare your answer to the original estimate ... do you need to double check your work? was your answer close to the estimate? why or why not?)

  • Sentence (give your final answer in sentence form)
