This presentation is a great way to review concepts with your students. I actually used the presentation at an open house to help parents better understand the challenging math concepts their students were learning in 4th grade. I have the kids use their white boards to answer the questions. With the parents I made the parents sit on one side of the room and the kids on the other. One parent had to sit in the "hot seat" and try to answer the questions. I let them call on the students if they need help and to check to see if their answers are correct. All in all, a lot of fun and very informative.
