Dear Amy: Where's a good homework site for math?--Allisha, Fort Collins, Colo.Dear Allisha: When it comes to helping kids with their homework, the Web is known mostly for finding information for a report. But some teachers and schools are trying to make interactive games and tutorials on the Web for kids to learn from. A good example is Flashcards for Kids at www.edu4kids.com/ math. You can choose whether to do addition, subtraction, multiplication or division and what degree of difficulty you want to try. It makes homework more fun.
