Students will become fluent in reading the first 100 sight words from the Fry list. Simply play the PowerPoint show and have students read aloud chorally. You can also use the show to assess students. All you would have to do is play the show on a computer and check off the words as students read them (there are a lot of free check lists on the web). There is a 3 second delay between words popping up.
In my classroom, I have this as a part of our calendar routine. Playing the show once a day really helps build the students' fluency.
