I wanted to share with you a great math site The Art of Problem Solving. It is truly a very unique web site. AOPS offers online subject classes for Algebra one and up. Their classes are very affordable, and they are OK with a variety of ages taking their classes. The classes have a big emphasis on problem solving, and your kids come out knowing math. You can also participate in up to 3 online-class-sessions before dropping the class for a refund.
They also have a FREE program you can use called Alcumus. Art of Problem Solving's Alcumus offers students a customized learning experience, adjusting to student performance to deliver appropriate problems and lessons. I would check it out.
All of the teachers are true lovers of math and have been involved in math competitions. Truly worth checking out.
Enjoy your Thanksgiving.
