We were in the same boat as you a few months ago. As a math teacher in public schools I was trained to dislike Saxon, and I did think it was repetitive and boring in a classroom. I did Singapore up through 3A with my daughter, and she liked it okay, but we supplemented with Miqon and Math Mammoth when I was worried she wasn't getting something (which was all the time!). I heard someone say that if your child isn't thriving with a curiculum then switch. Thriving wasn't the word I would use to describe her math. I borrowed a Saxon 5/4 and almost started it, but then thought I'd give Rightstart a try. She does not like Rightstart, although I make her play the games because I think they are great for reinforcing things. And now for the end of the story, I ended up getting Saxon 6/5 this school year and she loves it. SHe loves writing out all the answers in her notebook. She loves being somewhat independent of me in reading the lesson and trying it on her own first. She loves grading all the problems when she's done. All the stuff I thought she'd hate is the part she likes. We're not thriving yet, but this may be close! She's 11 by the way....
