I use this for a review at the end of the FOSS human body unit. This includes a sorting activity: Students cut out different examples of joints and sort them into the three types of joints (hinge, ball n socket, gliding). Also included is a matching activity to review vocabulary. Cards contain the vocab word and other cards contain the definition. Cut out and laminate these and then students play concentration or memory to review the words. Words include femur, ligament, phalanges, tendon, skeleton, skull, ribs and more.
