My son and I have been consumed this weekend by a fun new iOS game called NumBurst. If you like brain teasers and card games, this one’s for you! With two free levels and two paid levels, there’s plenty to keep you going as you try to solve these fun math problems. The basic idea goes like this: You’ve got a goal, which is a number, let’s say the number 3. Then you’ve got a bunch of cards, say 2, 4 and 1 and you’ve got to add them, divide them, subtract them, etc, until you hit your goal. The problems start out real simple, which is great for the kids and helping them learn math, but quickly get pretty darn challenging. Plus, you’re playing against the clock! Once you’ve completed a puzzle, you get the option to post that time on Facebook and try to have friends do the same problem and see if they can beat your time. Excellent for the competitive neatoramanaut, eh? You can download it here, or, of course, on your iPhone.
