is a "basic operations" math game in which the student has to decide which basic operation (addition, subtraction, multiplication, or division) is needed to solve the expression. There are 3 levels of difficulty for the expression. The easy level expressions have 2 numbers while the hard level expressions have 4 numbers. There is a "training mode" in which the student is only trying to complete the expression and a "race mode" in which the student is trying to complete the expression while racing a handheld to the finish line. The game claims that you can adjust the speed at which the handheld finishes the race, but even at the lowest settings the race is challenging. The game will use negative numbers in the answer, and I'm not sure when that concept is usually introduced to students.
