It is often hard to connect Algebra 1 to the real world, but I decided to take the opportunity to do so with x- and y-intercepts. This easily mastered skill was a perfect time to connect to the business world. This activity features a hook where students will graph the x- and y-intercept to discuss starting debt of a restaurant and break-even point, where the owner starts to make money.
This is followed up by two guided practice problems, two check for understand problems, and a dominoes activity. The way dominoes work, if you haven't used one before, is that I print the dominoes cards onto a colorful sheet of paper before cutting them up, shuffling them, and taping them around the room. In class students go in a scavenger hunt from problem to problem based on correct answers to practice a specific skill. My 9th graders always have fun with dominoes!
