Consider the following grading scheme for a public school mathematics class:

*COMPONENT % OF FINAL GRADEQuizzes (3 per unit) …………………………………… 15%Unit Exams*……………………………………………… *15%Semester Exam………………………………………….. 20%Homework…………………………………………………. 30%Projects/Presentations (1 per unit)……………… 20%*

*There are no quiz/exam retakes or corrections. The semester exam is cumulative. Homework is graded on a completion-basis only; if a homework assignment is completed on time, it receives full points; if it is completed one day late, it receives half points; if it is later than one day, it receives 0 points. Attendance is factored indirectly into the grade because homework is assigned most days, so if a student is absent then they will not receive full points for their homework that day. Projects/presentations span several days of class time and involve students working in groups on larger application problems and presenting their results to the class.*

*Letter grades are assigned in a traditional fashion: A+ (100-97), A (96-93), A- (92-90), and so forth.*

Thinking about this grading scheme, what does it mean for a student to receive an **A**? What does it mean to receive a **B **or a **C**? Overall, what does the letter grade communicate to the student about their mathematical learning?
