Introduce students to a prefix and its meaning using the posters. After teaching the meaning of the prefix, hang the hands somewhere in your classroom (I like to hang these by the door) and students must high five AND tell the meaning of the words. We make this a routine as we leave the classroom. You can also put on a ring and use for down time like at restroom breaks or waiting for specials or dismissal. These are a classroom must have! This could even be used as a bulletin board!
There are over 120 high five cards included!
