Broken Calculator
Broken Calculator Puzzles are great for getting you thinking. The idea of the puzzle is that you have only a few keys working on your calculator, and you need to try and get a variety of answer useing only those keys. The game below is an excellent flash version of the game created by D. Keith at www.subtangent.com, and comes with several levels.
Ideas for Teachers
Broken Calculator is great to get the students thinking from the offset. You can pick a level to suit your group. A discussion of what the symbols mean might be necessary with some, especially when squared symbols are included, but this can lead on to a discussion of order of operations or terminology.
