Equate looks a bit like Scrabble--for aspiring mathematicians, that is. Designed by a real mathematician, it works like this: You put down tiles on a board and make points by correctly completing simple equations. Your nine tiles include both numbers and mathematical symbols; you can add on to previous plays both vertically and horizontally. Learn simple stuff (like what division is) and more sophisticated ideas (like the order of precedence among arithmetic operations). It all adds up. --Richard Farr
