This interactive smartboard lesson practices the prefixes RE, DIS, and UN. It also puts in practice the suffixes LY, FUL, and LESS. It starts with simple practice of making new words and moves on to a jeopardy like game with 20 different tiles and 20 different questions. Two of the slides are linked to songs that play while children are working on the question at the click of a button. Fun for practice and review. All slides are self checking so it can be used in teacher directed whole group or as a station that is student directed. Entire lesson is rather lengthy and can easily be divided into 2 or 3 sessions. Great for Grades 2-4.
