This Math game should appear above near the top of this page - if you are having problems seeing it, try these steps. For further help, please see my product support page.
Look for a message at the top of Internet Explorer that says "To help protect your security, Internet Explorer has restricted this file
from showing active content that could access your computer. Click here for options....". Click the message, then pick "Allow Blocked Content" from the menu that pops up
so the game can work.
If there is no message, then perhaps you need to install Macromedia's Flash player. You can install it from Macromedia's website.
