JvermCaAge: 35-44Gender: female5 Stars Out Of 5Great supplementFebruary 20, 2013JvermCaAge: 35-44Gender: femaleI bought this to give my 3rd grader a little extra help with fractions. We are almost done with the first book and we really love it. The concepts build well on previous concepts and he is really grasping the concept so much better. I'm pretty sure he will be a fractions master once thru this series.
This book is worth every penny, price is right too!
Camille K5 Stars Out Of 5September 1, 2010Camille KI love the "Key to..." series! They are just perfect for that child that doesn't seem to really get math and struggles all the time. It makes learning math so simple. It is not as deep as most math textbooks but for a child that is probably not going to go to college or be in a math related occupation, it's more than sufficient.
