Mitosis and Meiosis sorting strip activity

Ask me for the sorting strips and then work with a partner to compare and contrast mitosis and meiosis. Make a column for 'mitosis' on the left, 'meiosis' on the right, and 'both' in the middle. When you check your answers, set aside any you got wrong and then call me over to explain.
