This activity allows students to practice and/or review algebraic input/output functions. Students will cut and glue boxes to the appropriate spaces on the main handout. The last table provides an opportunity for students to retain what has been learned by making his or her own input/output table. Each student will recieve both a Input/Output Tables handout and a strip of boxes to cut out and glue onto the main handout. (There are 3 sets of boxes to cut out per page to help save on copies.) I have included an ANSWER KEY.
