Using adapted sentences from the most excellent book Gregor The Overlander, the students will participate in recognizing why the example sentences may need revising and then be able to revise the sentences. The sideshow is uploaded in both Keynote and Quick Time formats. I have used this slideshow as warmups-one a day-and as a review lesson. They do not need to have read the book to enjoy it, however it may persuade some to seek it out. It is an extraordinary adventure with countless teaching points. I read it for many years to my fourth graders. Enjoy!
