This activity is intended to encourage cooperative learning and communication between students. Although it was designed to be a partner activity, it can be used by individual students. The activity includes two sets of cards with diagrams of the stages of the cell cycle & mitosis. One set of cards is labelled with the names of the stages, the other only has the diagrams. This set also includes a worksheet with follow-up questions to be completed by partners or individual students. The cards need to be cut out prior to use (preferably after laminating them). This file includes an answer key for this worksheet, background information about the cell cycle and relevant cell parts, and instructions for use.
