- Learning Goal 2
- In using mathematics, choices have to be made about what operations will give the best results. Results should always be judged by whether they make sense and are useful.

- Learning Goal 2
- For Grades: 6-8
- Learning Goal 2b
- Using mathematics to solve a problem requires choosing what mathematics to use; probably making some simplifying assumptions, estimates, or approximations; doing computations; and then checking to see whether the answer makes sense.
