This is a fun way to review the different types of symbiotic relationships in nature. Get students up and out of their seats as they look for their symbiotic match using the cards. Then, review the "correct" matches.
These are cards that identify and explain group member roles based on cell organelles and their functions for assigning roles in group activities or projects. There are larger versions that you can display to the class as you explain group roles. There is also a page of smaller cards that can be given to each group. These roles help organize group work while reinforcing cell organelle functions. My students love them!
