These worksheets can be used as starters/assessments or for homework. Each worksheet can be used for two weeks. The great thing about this group of D.O.L.'s (1 quarter/term worth) is that they are leveled/differentiated for high and low students. The highest level gives no help as far as mistakes, the second level tells how many mistakes there are, and the third level tells what kinds of mistakes. This allows the teacher to correct as a class while letting the students move up levels in their writing/editing/grammar skills.
