Connect Four: Order of OperationsThe classic Connect 4 game, but students have to first correctly evaluate the numerical expresson before they are allowed to drop their chip.
The Numbers GameA game styled on the British TV show Countdown, where contestants used 6 numbers and the usual operations and brackets to make the target number. This program has a great bonus - after you have found a solution (or not), the program will then list all of the solutions. It can be a rather humbling experience.
Make 24You are given 4 cards, the operations +, -, x, / and brackets. Your task is to construct an expression using all 4 cards that evaluates to 24. Oh, and you have to find an answer in less than 1 minute. Initially this task is can be very challenging, but the more problems you try, the easier they become. From Cool Maths.
