I posted on the other thread – so went back and cut out my reply. Here is my opinion:
I have 2 daughters who have tried PS math, Abecka, Saxon, Math Mammoth and the Activities for the AL Abacus. We are in the same boat as you, but I finally found what I think is going to work best with all 4 daughters. =)
Math Mammoth will probably not be very effective for your 8yo daughter. It is pretty brief in examples and goes through material very quickly. It drove me nuts trying to help my dd. Worksheets can be added to for more practice but my daughter with some learning issues really struggled with it anyway. It is a good program for kids grade 1-6 that can grasp math fairly easily I thought.
Then I tried Activities for the AL Abacus, which is like the forerunner of the RightStart program and it just drove her crazy. She had already learned her addition and most of the subtraction facts a different way and it was so frustrating to her. This one drove me nuts as well because the lessons weren’t really divided out into scripts.
I did buy RightStart since I heard so many fabulous things about it before she told me that the abacus was confusing her and making it harder. Well. Okay. =) It is a really strong program, but I needed something less stressing for her since she has learned it differently. Ugh. After completing Level E or G, they recommend movign to VideoText or something for the higher level maths.
Life of Fred I hear is awesome, but most people talk about it being a fun supplement to another practical program. I don’t have any of the books, but I am looking into getting them since I understand that they teach the whys of needing strong math skills. I don’t know if it can stand alone or not.
I let her take the placement tests for several curriculums and she has decided that Math U See is what she can relate to. This program allows her to physically move the numbers (blocks) as she is learning to do it. Math U See also goes through HS levels. It contains DVDs that help explain each concept, is mastery based, and I can reuse it for all my kiddos. =) So we are going to be using this program…
I hope this has been helpful and not more confusing. =)
