Here's a situation, think about it. Math education must provide skills that will be needed for at least 10 years after graduation. Quantitative literacy is one of the defining skills that determines who will be successful and who will not. In terms of professional or vocational success, quantitative literacy is as important as language literacy. Quantitative literacy is not the same as mathematical literacy.
Quantitative literacy is part of all subjects and the responsibility of all teachers.
Quantitative literacy deals with the most basic numerical needs of everyday life. Mathematics must permeate the entire curriculum. The numeracy unique to each discipline must be taught in that discipline. Using the case study approach is critical. Students must set up, solve, interpret, and present solutions to open-ended problems.
