Showdown is an activity that I like to use in all of my classes for students to practice concepts on white boards and for me to quickly check for understanding. Students will factor 9 expressions, find the zeroes of 3 equations, and graph 3 quadratic functions. They will do these problems on their white board, and when the teacher calls "Showdown!" they will lift up their boards for the teacher to check their answers. This PowerPoint includes the answers which will appear in the bottom right corner of each slide.
