This is a wonderful activity to get students up and around the classroom, talking with one another, and practicing finding inverse linear functions.
Directions for Setup:
• Copy and cut out function cards.
• Provide each individual (or pair) with a function card.
• Each student should have their own answer sheet for working out problems.
*Problems range from easy (1-8) to medium (9-16) to hard (17-24) to difficult (25 – 32). I suggest giving the brightest students the “easy” cards and the lowest students the “difficult” cards (because they will not solve their own card). In that way all students are challenged but still are able to solve all of the problems by the end of the activity.
Directions for Activity:
1. Students will find another student somewhere in the room.
2. Each student will work to find the other student’s inverse function.
3. Students will then check the opposite individual’s answer using the answer on the back of their function card.
4. If the answers are correct, they move on. If the answers are incorrect, students must rework the problem to correct it, but may use the other person for help.
5. Once both students have correctly found the respective inverse functions, both students look for another person in the room to repeat steps 2-4 with.
Directions for Grading:
• Answer sheet is provided for easy grading.
• I also give an automatic 50% for all students who show all work on their individual papers.
**Could also place cards in different stations/centers around the room for a group activity if desired!
Directions sheet, answer key, and student worksheet are included for easy implementation and grading!
