Number Sense: Factors and Products
There are many challenging math games and other interactive choices at this site. I think the products game is one of the most appropriate for 4th graders as a tool to help develop understanding of numbers and their factors. This link will take you directly to that game.
There is also a factors game at the NCTM site which you can play against the computer. This one is more challenging than it might first appear; if you play it, start with the smallest board (30). I hope you enjoy these games.
