Amazing series. I will buy the series 7/6 for next year for sure !!!! There is a lot of repetition if that is what your child needs. Mine learned a lot and things really sunk in. There are some wrong answers in the parent answer book so just keep watch on that. I will use this again when my 4 year old is ready to do this concept of math as well.
I have been HSing for 12 years. My oldest, who will be in 12th grade this fall, has always been a math wiz. He used A Beka math up through 8th grade and then switched to Saxon for high school using Classical Conversations. For him, A Beka was great.
My daughters, now 13 & 11, were not so naturally gifted at math. I faithfully started them with A Beka because my plan all along was to buy the books once and only ever replace the student workbooks for my younger 3 children. They started alright, but struggled quite a bit. By the time my youngest took EOY tests after 3rd grade, she fell in the 16th percentile for math. Pretty low! Also, math time was a lot of tears and frustration. We started her 4th grade year with strong resolve to build her math skills, but by Christmas, I could see we weren't making the needed progress. In January, I chucked her 4th grade A Beka math and started her at the beginning of Saxon 5/4. I had her first read every lesson and then attempt the practice problems. If she got it, she moved on to the mixed practice problems. If she didn't, I went back through and explained the lesson to her. (I purposely try to have my children be as independant learners as possible. I don't want them to think they cannot learn without a teacher.) We also go back and rework mistakes. Yes... That can get old fast, but it works! (We still do it this way two years later.)
Well, she began to thrive. She began to believe she COULD do well at math. At the end of 4th grade she was only halfway through the 5/4 book, but her math test score went up to 38th percentile. By the end of this year (5th grade) we had made it almost completely through Saxon 6/5, and I just got her test scores. In math she scored in the 51st percentile!! I know that's not super high yet, but in 2 years she gained 35 percentile points!!! I expect this growth to continue! Rome wasn't built in a day, after all! :-) Now, the math outlook is much brighter to both of us!!
Regarding my older daughter, without going into as many details, from last year to this year, (this year she completed 8/7) she has gone from 32nd to 75th percentile. An even bigger gain!! (I am super pleased! I only gave more details for my younger daughter because I feel like she and I have been in the math trenches together. Though the numbers are smaller, the gain feels SO much bigger.)
I do NOT by any means think that standardized test scores are the "be all and end all" of math proficiency. For me, they are a window into long-term progress (or failure to progress), and they are practice for the bigger tests (ACT/SAT) that they will one day take. This is just one of the many ways I assess our progress.
I also tutor a class of HSing high schoolers in algebra using Saxon. I know people complain about the repetition, but I find that to be a large part of what makes Saxon excellent. I'm a firm believer that repetition is the mother of skill. My girls' test scores confirm what I've been witnessing at our dining room table for the last 2 years... Saxon works!! (but only if you work it). ;-)
