Grammar Boxes 7.4 covers the difference between the words whose and who's, saw and seen, and of and have. Many students often have trouble with identifying which form of the word that they should be using.
This resource is part of a mini-lesson that students will complete. My students receive a mini-lesson over the topic on Monday, and then complete this sheet for homework. The sheet is due on Wednesday's. The topic is covered Monday through Wednesday of each week. We go over these sheets together on Wednesday's, and then students take a small quiz over them on Wednesday. That gives my students time to work with these skills in their writing on Thursday and Friday.
There are a total of 30 Grammar Boxes lessons that I have created, and can be purchased as a bundle for $20. These are all Word Documents and are fully editable.
