This unit features 9 weeks worth of vocabulary list featuring homonyms - both common such as their, there, they're - more unusual, such as reign, rein, rain. Each lesson has a list of that week's words and a fill in the blank / word bank quiz featuring sentences. Students have to carefully decide which homonym is correct. Each lesson contains an answer key. I used this successfully from remedial to advanced placement students. For some it was very challenging, for others it was an excellent review. Time for each week was about 10 - 15 minutes for kids to go over words when presented, and about the same for the quiz.
