I do not like Abeka...and my kids hated it. I felt that it was overly repititous in some areas and seemed light in word problems (back when I first started homeschooling and was using what the kids used at the private school that we had unenrolled them from). It was also very distracting for both of my kids. I dumped about a month later and went to something else. Abeka never seemed to have enough 'meat' in their curriculum to me. I felt that there were much better options out there for us.
We used Singapore for the next 4 years. Son liked it, but the pictures were distracting for him as he wanted to draw swords and shields for everyone in there (in the workbook as he wasn't allowed to write in the textbook). It would take him too long to finish, lol. He is good at math though and got it relatively quickly, including his sisters math who was two levels ahead, lol). The teachers book is well thought out and gives you problems and text to teach from. Daughter had a harder time with Singapore as she got higher. She needed more practice than what was given (although there are extra books for that if need be and it helped). She liked the program though. They also have a lot of word problems which I loved...the kids not always as much, but they were getting quite good at them.
We switched to Saxon this past year which has been better all around (and many people who finish with singapore 6B, switched to Saxon). Lots of practice and teaching. Each lesson begins with a short mental math warmup, then has 2-4 pages of reading to be done by the student (or with mom if need be), followed by the lesson practice and then another section of work for reviewing previous lessons. They have an ample amount of word problems and many of the problems require multiple steps in the higher grade levels. Our children are in books 7/6 and 8/7. We did buy the DIVE Cd's for our daughter for 8/7 to help facilitate her learning (I'm not a math whiz either) and will continue to do so for the upper leves with our son also being able to use them when he gets to that point (they are like having a teacher in the home and he uses completely different problems in his lecture than in the lesson. There are teacher Cd's too where the lady goes over the lesson itself in it's entirety and there is a section that works every problem in the actual lesson-I don't plan to get that one though). WIth the CD's and book, my daughter has been mostly working on her own now, which never happened before. She feels much more confident with this set up.
I found TT to be a bit 'behind' than what I've used and now using and there were not a lot of word problems. It is uninvolved for you though and they can repeat and repeat a lesson should they need to. I did like the concept and the program, actually buying level 7, but my daughter surpassed half of it fairly quickly within Singapore and then she fell right into the Saxon Math level that we were looking at so we started her there instead. I sold the TT. Now though it seems 'behind', every curriculum has it's own syllabus and it will end up covering all the student needs by the end of highschool, from what I've seen. My friend loves it and I liked it as well, but it didn't fit us at the time.
Hope this helps!
