This excel sheet can track assignments as being complete, missing, late, or incomplete.
It has room for 30 students and can track up to 100 assignments for each of ten subjects. Updating names on the totals page will update names across the other ten sheets. Deleting sheets will break the totals page, but the names of subject sheets can be edited.
This is not for tracking grades. It is meant as a quick and colour coded visual to see which assignments your students need to hand in.
