I belive the math race is for 3rd grade and above. DS7 worked on it last night for about 2hrs. I am still having some computer problems, Lock ups, partial page downloads. I am pretty sure its on my end. Too much junk in our computers. DS7 likes the program, he understands how it works. By the end of the week I may stop monitoring. Some of the math, espesially the part on Sets is new to him. I also like the way they break down word problems.
