It's a long way around Perimeter Path! Mike's brother and sister say he's too young to compete in the 15-kilometer bike race. But if Mike just gets a chance, he knows he can make it all the way around.

Jenny and Jeff are driving their little sister, Jill, crazy, and now that the family is moving into their new house it's worse than ever. Who'll have the bigger window? Who'll have the bigger bedroom? How can they measure the space so that they'll know for sure?

Jenny and Jeff must calculate area to settle their debate. This simple geometry concept will prove once and for all whose room is bigger -- but maybe Jill can show her squabbling siblings that bigger isn't always better!
