Printable math workbooks · Grades 4–9
Nobody gets strong by watching someone else lift. Muscle Math Mania builds workbooks that give your child the one thing that actually moves the needle — steady, structured practice, with every single answer worked out in the back.
Why this exists
Somewhere between fractions and algebra, a lot of kids quietly decide they're "not a math person." It usually isn't ability. It's a gap — one skill that never got solid, sitting underneath everything built on top of it.
Miss how negatives work and every equation after it gets harder. The problem shows up months later, in a subject that looks unrelated.
A number tells a child they were wrong. It doesn't tell them where. That's why our books show the work, not just the result.
Every page is designed to be picked up cold and finished in one sitting — by your child, without you re-learning it first.
The method
Not random busywork. Every lesson in every Muscle Math Mania workbook is built the same four ways, so your child always knows what's coming next.
A short, confidence-building start that wakes up what they already know.
One problem solved all the way through, step by step, so the method is visible.
The reps. Enough repetition to make the skill automatic, not enough to become a chore.
One problem that asks for a little more than the page before it. That's where growth is.
The workbooks
Each book stands on its own. Together they carry a student from long division all the way to the doorstep of Algebra 1.
The four operations, fractions, decimals and mixed review — the bedrock everything later stands on.
Integers through functions and graphing — the fundamentals a student needs walking into high school math.
We're building out the series. Join the list below and you'll hear the day the next one lands.
Keep me postedLook inside
No mystery. This is exactly what your child opens to — clean layout, room to work, and a footer telling you which page the answers are on.
Built for the parent, not just the kid
Not a sample. Every problem in the book has its answer in the back matter.
The hardest problems get a full step-by-step walkthrough, so you can help without re-teaching yourself.
The digital edition is a household licence. Reprint a page your child wants to redo — or run it for a sibling.
Paper and a pencil. Nothing to subscribe to and nothing that expires.
Free, no card needed
Get a free ten-page sample packet — real lessons, real practice, and the answer key that goes with them. Print it tonight and see how your child gets on before you spend anything.
We'll email the ten pages straight away. After that, three short notes about how the books work — then nothing. Unsubscribe in one click, any time. We ask for an email address and nothing else, and we never sell or share the list. For grown-ups, please — see our privacy policy.
Straight answers
We won't promise that, and you should be wary of anyone who does. What we can tell you is what's in the book: sequenced practice, worked solutions, and every answer keyed. Practice is what builds skill — but this is practice, not a promise.
Go by what your child can do, not by their school year. If fractions, decimals and long division still feel shaky, start with the Grades 4–7 book. If those are solid and algebra is coming, the Grades 7–9 pre-algebra book is the right next step. The free sample is a good way to test the level before deciding.
No. Each lesson opens with a fully worked example, and the toughest problems have a step-by-step solution in the back. You can follow along beside your child rather than teaching it from scratch.
Both, as of today. The content is identical — pick the format that suits how your child works.
Paperback — $34.99 on Amazon. Printed, bound and shipped by Amazon, with their returns and delivery behind it. Best if you want one book that lives on the kitchen table and survives a school year.
Digital PDF — $19.99 for Grades 4–7, $24.99 for Grades 7–9. Downloads immediately and is licensed for your household, so you can reprint a page your child wants to redo, or run the whole thing again for a sibling.
Yes. The digital edition is licensed for your household, so print as many copies as your own children need. It isn't licensed for a classroom, a co-op or resale.
Most lessons are built for a single sitting — roughly fifteen to twenty-five minutes, depending on the child and the topic. It's designed to fit a school night, not take one over.
