Fifteen problems. Two hours. No multiple choice.
The Mathworks Math Contest asks middle-schoolers to do what a classroom rarely asks: not merely to get the answer, but to show how they got there, in writing, to someone who will read it. In 2025 it drew 962 students from the United States and abroad. The average score was 2.72 out of 15. Fourteen of those 962 scored twelve or better.
This book teaches that.
375 problems written for the training camp at ACES Learning Center in Austin, Texas, in four parts and twenty-four topic chapters — rates and work, angle chasing, lattice paths, invariants, cryptarithms, modular arithmetic and the rest. Every one is worked through from scratch.
Every problem gets three things
- A solution that explains itself — not just the steps, but why you would think of them, and what you would have tried first.
- A sample written solution, set in handwriting: the short, labeled write-up that actually belongs on an answer sheet, with the answer boxed. Not a paragraph of prose, and not a page of scribble with a number circled at the bottom. This is the part almost no student is taught.
- A second look, wherever one exists — the shorter route, the cleverer route, or the one that explains why the first route worked.
The companion sets are the heart of it
Forty-seven times in this book, a problem is followed by two or three more that use the same method, and then a short box headed Taking stock. A method you have seen once is a trick. A method you have seen three times, in three configurations, with one case where it nearly fails, is a tool you own. The last problem in each set bends the method until you can see its edge — the configuration where the obvious version gives a clean, confident, wrong answer.
Built as a course, not an answer key
Each chapter opens with the skills that unlock it, stated as tools with their actual formulas rather than as topic headings, and closes by naming its hardest problems and the one idea that cracks each.
Where the problems come from
The companion problems were written from scratch for this book. The core problems are adaptations: each began as a problem from the published record of middle-school competition mathematics, including past MMC and PMWC papers, and was rewritten here with a new setting, new names, a redrawn figure and, nearly always, different numbers. Nothing is reproduced word for word, and no contest answer key was used. Every solution was worked out from scratch by the ACES coaching staff — coaches of national-champion MATHCOUNTS teams — and checked line by line.
A companion Workbook contains all 375 problems with room to work and nothing else.
For students in grades 6–8, for coaches who want a year of ready material, and for parents looking for something harder than the textbook and kinder than a wall of answers.

Information regarding the right of withdrawal
Statutory right to withdraw
You have the right to withdraw from this contract within 14 days without giving any reason.
The withdrawal period will expire after 14 days from the day on which you acquire, or a third party other than the carrier and indicated by you acquires, physical possession of the last good or the last lot or piece.
To exercise the right of withdrawal, electronically fill in and submit a clear statement on our website, under "My Purchases" in "My Account". We will communicate to you an acknowledgement of receipt of such a withdrawal on a durable medium (e.g. by e-mail) without delay.
To meet the withdrawal deadline, it is sufficient for you to send your communication concerning your exercise of the right of withdrawal before the withdrawal period has expired.
Effects of withdrawal
If you withdraw from this contract, we will reimburse to you all payments received from you, including the costs of delivery (except for the supplementary costs arising if you chose a type of delivery other than the least expensive type of standard delivery offered by us).
We may make a deduction from the reimbursement for loss in value of any goods supplied, if the loss is the result of unnecessary handling by you.
We will make the reimbursement without undue delay, and not later than 14 days after the day on which we are informed about your decision to withdraw from this contract.
We will make the reimbursement using the same means of payment as you used for the initial transaction, unless you have expressly agreed otherwise; in any event, you will not incur any fees as a result of such reimbursement.
We may withhold reimbursement until we have received the goods back, or you have supplied evidence of having sent back the goods, whichever is the earliest.
You shall send back the goods or hand them over to California Books, Fort Wayne, Indiana, U.S.A., without undue delay and in any event not later than 14 days from the day on which you communicate your withdrawal from this contract to us. The deadline is met if you send back the goods before the period of 14 days has expired. You will have to bear the direct cost of returning the goods. You are only liable for any diminished value of the goods resulting from the handling other than what is necessary to establish the nature, characteristics and functioning of the goods.
Exceptions to the right of withdrawal
The right of withdrawal does not apply to:
- The delivery of newspapers, journals or magazines with the exception of subscription contracts; and
- The supply of digital content which is not supplied on a tangible medium (e.g. on a CD or DVD) if you accepted when you placed your order that we could start to deliver it, and that you could not withdraw once delivery had started.
