I just discovered a great new math website I think you will LOVE! It is called Cyberchase and was created by PBS Kids. I have a feeling you will come back to school next fall a SUPER-DEE-DUPER MATH WHIZ after playing these games!
There is also a an activities page with several different math activities and games you could print out to work on or play when your parents need their computers back.
Try a few of the games and activities and then drop us a line letting us know which ones were your favorites and why.
Can't wait to hear from you!
P.S. Don't forget about IXL! You can practice your subtraction math facts, time, money, place value and math problem solving.
