Grammar worksheets directly from the text of The Phantom Tollbooth. GOT GRAMMAR? We do! What's more, your students will get it faster and easier with our GRAMMARGATOR GUIDES to chapter books and young adult novels. Each Grammargator Guide contains 12 worksheets of 20 sentences taken directly from the books your students are already reading. Each group of sentences focuses on a specific grammar skill, such as locating the subject of a sentence, identifying verb tenses, or finding a pronoun's antecedent. Because Grammargator exercises incorporate grammar lessons and review into your existing unit plans, they are not only easy to use but highly effective in reinforcing key reading skills, as well. Best of all, you can teach grammar in the context of the literature your students are reading anyway.
