Unit 4: Whose, Who’s; Fewer, Less; Choose, Chose
PDF: Whose, Who’s; Fewer, Less; Choose, Choose
Word: Whose, Who’s; Fewer, Less; Choose, Choose
This is the fourth unit of conventions, with overheads for introducing information, overheads for whole-class practice, worksheets, and a quiz which includes concepts covered in Units 1-3.
Again, I recommend following a three-class-session structure, with the first day being an introduction of concepts, the second day a review, and the cumulative quiz on the third day.
