"In Teaching Kids Real Math With Computers Conrad Wolfram claims that the hand calculations most math curricula requires is irrelevant to most real world mathematics applications. Wolfram argues that students should instead be taught to apply mathematics to computer programming. Wolfram points out that problems aren't dumbed-down by computers and, in fact, can be made more challenging by computer programming. Wolfram also claims that the real problem with current mathematics instruction is that "we have dumbed-down" problems. I can't say that I agree with everything Wolfram says, but he will make you think about about instruction. Watch the video below."

Strategies to solve addition/subtraction different than tradiitional algorithm 

Step 1.) Think you're good at math? Prove it to the most famous mathematical thinkers in history. In Genius Boxing, you must defeat Albert Einstein, Pythagoras, Galileo, Bill Gates, Leonardo da Vinci, Nicholas Coperniucs, Archimedes, and Sir Isaac Newton in boxing using your math skills. Step 2.) Look at the number equation that appears at the bottom of the screen. Click on , or = to make the number equation true. Be careful though, each round gets much harder!
