About Common Core Math Standards
Not every student of yours will grow up to be an accountant, but that doesn't mean they should treat numbers as though they're imaginary...except for imaginary numbers, of course.
The Number and Quantity standards cover everything your students need to know about numbers, whether they're alone or in groups, rational or irrational, real or imaginary. (Tip: Don't let your students file imaginary taxes.)
