Basic differences are of course, mastery vs spiral, and textbook (after gr 2) vs. worktexts. Both go through gr 8, although Alg 1 should be available by the time you need them. Both have them in the works but not ready now.
While both are “classroom” materials, they are primarily used in one-room schoolhouse settings. So, they still work very well for us as hsers.
After 8th (or 9th – Alg), you would still have to switch to another math for HS. I would switch before Alg, just to keep it all the same company. I use R+S and switch to MUS or VT for HS.
I have tried many, many maths and we all keep coming back to R+S. They all basically ASKED to go back to R+S. One after trying BJU 6 – didn’t even get through the first chapter; the 2 youngers just this past week – after starting MUS at Gamma.
The benefits I’ve found using R+S is that it’s very easy to skip the sections they know well. Because it’s mastery, it’s easy to know which ones to choose. Also, I’ve had them do just half the problems in a lesson, which can be plenty. This also gives extra practice for those sections/dc who need more practice. There is built-in review in each lesson, another plus for us. Another benefit w/ R+S is that the texts are written right to the dc from gr 4 up. But, even w/ gr 1 – 3, I’ve been able to tell them what to do w/out needing the TM, even my dc were able to know what to do most of the time.
As for the TM, I primarily use it for an AK. I “get” math so it’s easy to teach. If I need to, I can read over their lesson and teach from that just fine. But, if I need it, I can use the TM for some other ideas to help w/ understanding, along w/ some extra practice when needed. And, it’s not overly expensive, especially the few consumables. I have a friend who struggles w/ math and found R+S easy to use w/ her dc. It gave her the hand-holding she needed when she needed it. It gave her the confidence to teach math.
It can get boring at times, but what can’t. There’s not a lot of variation, especially at first while they’re learning their math facts (lots of practice). They do include money, time, shapes, basic fractions, etc at the same time, so that’s a help. At the same time, this repetition has helped solidify the facts for my dc. My dd knew them inside-out when she was done w/ the gr 3. She’s lost a few since then, but I know by working through it again, she will regain it quickly. My ds fought me to finish gr 2 and was excited to start MUS, but even he asked to go back to R+S, and has since sat up and finished the lessons in record time. He knows his add/sub facts lickety-split. Another plus to the mastery is it will be easy to add in games and other fun things that will practice what you’ve learned. (Not that you can’t w/ a spiral approach.)
I’ve been very pleased w/ R+S and I know lots of people who feel the same way about CLE. Both are solid and reputable. You can’t go wrong either way.
I guess the question to ask yourself is why isn’t MUS working well. If he’s like my son, though, it won’t matter what you choose. He’s going to want to be jumping around and avoiding anything sit-down like the plague – even choosing chores over schoolwork. LOL If it’s any consolation, my ds will be 11 this summer and he’s finally “getting it” about sitting up and doing his work. He’s done very well w/ that this past week. Little trouble today, but it’s been crazy in a new way as we adjust to summer and different things happening, particularly w/ the older boys.
Sorry, this ended up longer than I thought.
HTH,
