I was actually thinking the same the more I looked into BA. I had thought I knew what to do for the 5th grader and was really exploring options for my 3rd grader. He loves stories and characters and so this jumped out at me for that reason. The more I read, the more I thought my older, more puzzle-minded, son would enjoy the challenge.
I will say that, though my second son doesn’t LOVE math as much as his brother - he isn’t quite as mathematically minded, he is very gifted and learns quickly. To be fair, since I never had to “teach” my first, we were sort of in that rhythm of skipping the lessons and the textbook and just doing the workbook, CWP and IP. The sweet second boy kept up, though, and held his own. I just know I’m doing him a disservice, and he deserves a real teacher.
I feel confident that he will succeed with the guide book, video lesson and added practice, if needed. I am not as certain that he will love it. Of the two, he is much more enthusiastic about it. My oldest one cares not at all about characters and stories.
I so appreciate experienced homeschooler’s opinions - so thank you so much for processing with me!! Honestly, if SM had more video support, I’d just stay with it since neither were begging to switch, and have thus far succeeded in learning the concepts with very little instruction. The only real glaring hole is that my 8 year old is struggling to understand time associations - like “a quarter until 3 is 2:45” - but I haven’t taken the necessary time (ha pun) to reinforce and practice. We don’t love the SML videos, and would have to switch to another version for other third party support. These others don’t include help for the CWP and IP (which I agree with SML, who advises that is the only way to actually get the results for which SM is known). Everything I’ve read says it is not advisable to switch to dimensions this late in the game from other versions, and that is the only “SM” program that provides video support. I’m thinking through using only the workbooks (dropping IP and CWP) for 3 with my 3rd grader along with BA 2 - and SM 5 workbooks with BA 4 for my 5th grader. It might be too much but perhaps not, and at least I’ll be getting progress reports and testing which we weren’t doing with SM. At the risk of completely losing you, at this point, I should also say that neither ever had trouble with the workbook problems with SM - only with the CWP and IP occasionally. Neither like doing the work, mind you, but the workbooks were easy for them both - with minimal textbook assistance.
