As we go over worksheets in class, students are supposed to correct any mistakes they made. We go over every worksheet the day that it is due.
If any student has questions or concerns about grammar things that they are not understanding, they should come and see me at lunch, so that I can explain it one on one.

"z" changes to "ces":
