Totally doable — I’ve used 'Math Mammoth' to plug
Holes in middle school math for kids who’ve missed fundamentals, and it works surprisingly well when you use it deliberately.
What I like most is the modular design: short, focused chapters on fractions, integers, ratios, proportions, basic algebra, and geometry let you zero in on the weak spots. I’d start with a quick diagnostic (the free placement tests are handy), pick the exact worktexts that map to the gaps, then use the clear worked examples and practice pages to build confidence. There are plenty of varied problems — procedural drills, applied word problems, and some thinking tasks — so repetition doesn’t feel stale. For students who need conceptual grounding, I pair a page or two of 'Math Mammoth' with a hands-on activity or a short explainer video to connect the symbols to real ideas.
One caution: it’s not flashy. If a kid craves gamified learning or tons of animations, you’ll want to mix in apps or videos. Also, older students with big gaps may need
Closer one-on-one coaching to unpack misconceptions rather than just more worksheets. But used as a targeted, mastery-focused tool, 'Math Mammoth' shines — clean explanations, lots of practice, and super affordable. My last learner moved from guessing through word problems to showing clear steps within a couple months, and that felt great to watch.
