Hi,
I've been using Math Mammoth this year. This is our first year homeschooling so I have nothing else to compare it to. I heard nothing but wonderful things about it before we decided to go with this program, but I don't know if we're going to use it next year. I have a first grader and a third grader using it. Pretty much all of first grade (so far) has been learning the addition and subraction facts. Third grade started off with a review of addition and subtraction of double digit numbers, then off to multiplication tables. We've also done time and he's starting the unit on money after Christmas.
Good points first....its a very solid curriculum and the kids have learned a lot along the way. It's all work...there aren't any superfluous pictures or exciting fonts wasting valuable page space. What you see on the website is what you get.
The author does not use any manipulatives, which, depending on your situation, might be a good or bad thing. This is pretty easy to solve...just use dry beans or buttons to show your point. She does use pictures to make the lesson more concrete...but they're pretty basic pictures. Such as, three circles and four circles makes how many circles? Again, the website has good examples of this.
The author is very good at drilling the concept about why certain things are true. The example above with the circles is used over and over again for all the addition math facts. She wants the child to see why an answer is correct, not just that it is correct.
She also uses word problems to apply the lesson being taught to real world situations. I really like the word problems, and they're very relatable to the kids.
In my opinion, I don't think there is enough review included in the lessons. This is a mastery based program, so the lack of review doesn't surprise me, but I am surprised at how much it bothers me so much that it's missing. Does that make sense? I guess I didn't think it would be a such big deal. The author uses the same pattern to teach each new addition/subtraction/multiplication fact, but even though the pattern is the same, it's a whole page of new things every day. (there is some review naturally built in with the math facts...for example, you'll learn 2 + 3 =5 on one day, then the next 3 + 2 = 5...and she's show you how the two are related.) The author does provide lots of math website suggestions where the kids can review the the facts they've learned. OUR problem with this is that by the time the kids finish their math assignments, the last thing they want to do is more math, even if it is a "fun" game. Also, since the computer is not in the same room where we homeschool, the kids and I lose our momentum if we have to switch gears and get on the computer, look for the website, etc.... This probably sounds like a non-problem for most families, but it is an issue for us. We would be better off having a review section with each lesson. So it sounds like a spiraling approach would work better for us, and that's what I'm looking into for next year.
There are also LOTS of problems on each page. Think "lots of drill" and that's what you get.
Finally, I had read that the kids would be able to do a lot of their math independantly--that the instructions are pretty self-teaching. That has not turned out to be the case with us. I heard it was self teaching from lots of different reviewers, so this may just be my particular situation.
I hope I don't turn you away from it, as I did hear only great things about it. I think maybe our family might be the exception. And, since this is our first year, I might be getting "the grass is greener" syndrome. On the website you can order just one unit for pretty cheap (I think it's a downloadable version for about $4.) Maybe you could try it out like this before you splurge on the whole program. If you do end up using this curriculum, I highly suggest getting the printed version with the CD that WP sells instead of just the CD. Otherwise, you'll have to print out the whole book and it will probably cost you more in the long run on toner and paper. Last thing...you don't get an actual book when you order the printed version. You get something similar to the a stack of math pagers that are 3 hole punched and you have to put all the pages into a binder. They're only printed on one side, so it looks like a lot more pages than your average math program.
Sorry this is so long....I just wanted to be thorough because there isn't a lot of information about this program on line. I hope this helps!
