In algebra, we are not only adding or subtracting. We are not only solving problems with the usual operations students are used to solving. We are also solving problems that include a missing variable. In this game, students will solve linear equations that have a missing variable. In most problems this variable is denoted as “x”. You have to find the value that makes the equation complete. While solving each problem, students will also enjoy the fun of playing a zombie game. This game is suitable for Halloween algebra activities. Hit the start button to begin. For fourth grade, fifth grade, sixth grade and seventh grade students.
