Basic digital Common Core-aligned gradebook through Excel. Input grades by standard to ensure you are covering and assessing each one in class. Each sheet (one sheet per standard) allows up to 50 assignments for up to 29 students, then automatically averages any data for each standard. Grades can be percentages or standards-based (4, 3, 2, 1).
Update: Now includes a final sheet which averages all scores across all standards.
