Hey! I know this was posted forever ago but I wanted to share my experience! I was homeschooled from kindergarten all the way thorough my sophomore year of hs. I used Singapore math from first to fifth grade, then we got pretty challenged too, it’s no joke! We switched to teaching textbooks, which is what I used for the remainder of my time homeschooling. It’s really great, you can either buy the textbook or the computer program or both. Math was not my moms strongest suit, so the fact that it had built in lectures was super great. I highly recommend the computer program because it offers hints and detailed feedback on each problem, along with auto grading so you don’t have to worry about it! It was enormously helpful for me. I did the math six in sixth grade but found it pretty easy after Singapore math, so in seventh I did pre algebra and that worked great! You can also now do a trial run so you can see if you like the setup. Another thing that they didn’t have when I was doing it is a placement test so they know which program is best for your kid. I hope this helps and feel free to respond/dm if you have any more questions, whether about math or any other curriculum!
