Designate each of your classroom table groups as a University/College name! I am from Florida, so I use each of the major colleges for my table groups. Attached you will find the document I created for my team/table captains. I laminated and cut out each one and glued a magnet on the back. I have them placed on my whiteboard as an easy visual and can change the student's name (table captain) with a whiteboard marker each week. This is also a great way to get your students exposed to the possibilities of attending a state university in the future!
I have been teaching for 5 years at a Title1 school in Tampa, Florida. I taught 5th grade for three of those years and am currently teaching 3rd grade. I absolutely love my job and my students!
