If your students are anything like mine, they need to be reminded periodically the use of different words. For example, they still confuse there, their and they're and too, two, and to. This activity is a way the students can help each other review the different usage for these words and others. It is creative (they need to create a poster to put on the classroom wall to remind other students), and it is interactive (they need to get in front of the class and teach a lesson on how to use the different forms of their words correctly. This lesson also includes a learning goal and rating scale to use with your students.
