In this unit students will review and learn different classifications for number sets and then move on to operations involving each of the number sets.

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)
