These are three different relays that student do to practice slope-intercept form. They are given an equation, and each step has a student do something to the equation. You can do the relays several different ways. One is that you line your students up in rows and give the paper to the first student in each row. They are not allowed to talk to each other, just pass the paper back when they have completed their step. When they get the paper, they can check the previous work, but they can only do their step. Once the last person is finished, they let you know and you check it. If it is wrong, they are allowed to work together at that point to fix their mistakes and find the correct answer.
The other way I play this is by letting the students actually run up to a board and fill it out one at a time (same rules apply about talking). If you do this method, hang another piece of paper on top of their relay paper that way other teams are looking.
This is a great way to practice this important skill!
