We’ve tried a lot of different math products over the years. A lot. And there are very few that my kids don’t complain about – usually the ones that are “fun,” meaning game-like. When a review opportunity for Math Mammoth came up earlier this year, I had the older two (7th and 5th graders) take the placement test to figure out whether this would be a good fit for us. Color me surprised when Seahawk (7th grade) barely understood anything in a test below his official grade level. (I don’t remember offhand whether I had him take the 5th or 6th grade placement test.) I decided at that point that perhaps it would be a good idea for us to request this review in order to fill some learning gaps that apparently exist in our homeschool.
In order to work with both of the kids, I requested the Blue Series, which is a set of books (available as PDF downloads or physical print books) that focus on specific topics. We received
- Multiplication Division 3 (grades 5-6, 130 pages, $7.40)
- Percent (grades 6-8, 80 pages, $4.10)
- The Four Operations (with a Touch of Algebra) (grades 5-6, 128 pages, $7.30).
Seahawk has been working through the “Percent” worktext, and Munchkin has been doing “Multiplication Division 3.” I’m saving “The Four Operations” for later, and they will both do it when they’ve completed the book they’re currently working through.
Each day, I would take turns sitting with the boys in turn, working through the problems. The explanations were clear, and there was very little I needed to explain beyond what was actually in the textbook itself. The boys didn’t have any difficulty understanding what they needed to do, and they required minimal guidance from me. I was mostly there to keep them on task and see how the program worked for the purposes of being able to write the review later.
We’ve been using the texts nearly every school day for several weeks, but they still have plenty of work to do before they finish these. Seahawk is about 1/4 of the way through Percent, and Munchkin is about 1/5 of the way through Multiplication Division 3. Their slow progress isn’t because the concepts are difficult or the program bad, though. Rather, it’s because the concepts are taught and practiced so thoroughly that there are loads of problems in each section so that children can have ample opportunities to practice what they’ve learned.
Whenever I opened the PDF, it would remind me that “This PDF can be completed using the Add Comment tool.” I took that to mean that it was an interactive PDF, meaning that the child using the product would be able to fill in his answers right on the computer. I didn’t find this to be the case at all, and a Google search led me to looking at the settings on the PDF, which told me that it wasn’t an interactive PDF after all. I’m not savvy enough to know about the Add Comment tool or how that’s different from an interactive PDF, so we treated the PDFs like a textbook: the kids would read the information and problems on the screen and write their answers down on notebook paper kept in their binders. I could have printed the pages out for them (and I did one day when I wasn’t available to sit with them individually), but for the big picture, that would have been cost prohibitive to do all the time. In the end, the notebook-paper-approach was the right one for us.
I mentioned earlier that we’ve done a lot of different math curricula over the years. What I didn’t mention was that Math Mammoth is one of the best. Not only is it very thorough with clear explanations, but my kids don’t complain about doing it. In fact, quite the opposite has proven true: every time we finish a lesson, they tell me that they really like this curriculum. With the prices being so reasonable ($2.20 to $7.40, depending on what the book is), I can see us buying more of these. When used together, they make up a full curriculum for grades 1-7. Math Mammoth also offers an “official” full math curriculum for these grades called the Light Blue Series. I haven’t seen this, so I’m not entirely sure how it differs from the Blue Series. The Light Blue curricula costs $37.50 per year, and the final year (grade 7) is a full-fledged Pre-Algebra curriculum. Upon completion of that year, your student is ready to tackle high school level math.
Our official opinion: Math Mammoth is amazing. It teaches the concepts well, is very affordable even for families with multiple children, and is better than a regular textbook (in my kids’ opinion; I’m not sure how it differs other than that they don’t whine and moan when I announce that it’s math time). I definitely foresee us continuing to use this product in the near future.
