Over the past five years I have developed and implemented 20-25 group exercises in the classroom setting in a senior level inorganic chemistry lecture without appreciable loss of course content. These exercises allow the students to try the calculations or apply a theory and discover what they do and don't understand in the classroom setting. It also has allowed me to understand and quickly correct errors in student understanding of the material. I will discuss the range of activities such as Jeopardy games to make reviewing more interesting, strategies for implementing the activities into the lecture and the observed outcomes.
