This PowerPoint game provides students with practice for finding the slope m of the graph of a linear function. There are 35 unique bingo cards in PDF form, each with 25 different graphs of linear functions. Students write the slope of each line on their bingo card in the space under each graph before the Power Point Game begins. When Power Point is enabled and in slide show view bingo balls bounce around on the screen, simulating real balls in a bingo machine. Student select a bingo ball either by touching a ball on a Smart Board, using a stress ball to hit a ball on a Smart Board, or going to the screen of the computer running the program to select a ball. Once a bingo ball is selected, a graph appears on another slide and to the right of the graph is the slope of the line. An arrow links you to an Excel file inserted in the Power Point. This file allows you to see all 35 bingo cards, mark selected slopes, and determine which card(s) have a bingo.
