This product features 8 planets worth of Fry words (1-800). Each page has a planet associated with it and features 4 lists of 25 fry words for a total of 100 fry words for each planet. On a bulletin board I have a purchased set of planets. As students are able to read each set of 25 words they get a sticker on their list but also on a spaceship. When they have read successfully all 100 words and filled up their spaceship, they get to put the spaceship by the planet for the list they just mastered. Students get so excited to be able to fill up their spaceship and to move on to the next planet!
