This week we had a very special guest speaker, Dr. Steve Hall. Dr. Hall is a college professor who came to our class this week.  He spoke to the students about how important math is and he taught the class a lesson on factorials.  He taught a lesson to his college students about factorials last week!  The class was so enthusiastic about learning and Dr. Hall was just as enthusiastic about being here!  It was a fun time for all involved!
