My second graders loved it and it became a favorite activity for students to do whenever they finished their Word Study work early. At the end of every six weeks, we would play the game as a class. Using this gameboard or just using the patterns we had studied that grading period, I would write the patterns on the board. Students thought about the patterns and noted their words on mini dry erase boards. I would have them stand up and we would go from student to student asking them to read aloud their word for the #1 pattern. If the other students heard a word that they had written down, all with that word had to sit down. After each student had read his/her word, all of the students still standing received one point for their words.
I love this game because, not only does it work on reviewing spelling patterns, but it also works on the important skill of learning to activate one's prior knowledge. My competitive students quickly figured out that the more creative or unusual the word, the more likely they would remain standing at the end of each round.
