Math Mystery Worksheets: The Math Page That Ends With “Who Did It?”
A whole tray of cookies has vanished from the bakery window. Seven suspects stare up from the bottom of the page. Above them, six sums.
Your student works the first one, 105 + 64, gets 169, finds 169 on Morgan’s tile and crosses Morgan out. Next sum, next suspect gone. By the fifth answer the pencil is moving faster, because now there is a reason to finish. When the last sum is done, one face is left on the page: Riley. Case closed.
That is a Math Mystery page. The child does the practice, and the practice cracks the case.
Math Mystery makes that page for the skill your class or your readers need, at the level each child can handle, and hands you the key with it. Times tables, adding and subtracting within 1,000, fractions, elapsed time, word problems: pick one, pick a mystery, print.
Make your first mystery free in the demo, nothing to buy first.
Why Do Kids Finish a Math Mystery When They Drag Through a Drill Sheet?
You know the fast finisher who is done in three minutes and asking what’s next, and the slow starter who stares at problem one. A plain page of sums gives neither of them a reason.
A mystery does. Every answer moves the story forward, so problem six matters as much as problem one: skip it and the case stays open.
You have probably bought a mystery pack. Six pages, gone in a lesson, and Thursday’s skill has no mystery at all. Math Mystery hands you the maker instead of the pack: the skill your class is on this week gets its own case, and so does next week’s.
Three Ways to Crack the Case
Themed: whodunit, and where
A short story sets the scene and a row of suspects waits below the problems, each with a portrait, a name and a number. The suspect left over did it. Add a second section and the second row of tiles becomes places, so the page answers who and where, each section on its own skill if you like: sums for the culprit, elapsed time for the hiding place. Three built-in cases come ready to use, The Missing Trophy, The Great Cookie Caper and The Museum Mix-Up, with 16 suspects to choose from and 16 places for each case.
Secret message: the answers spell it out
Every answer points to a letter in the key, the child writes the letter in the box beside the problem, and the boxes spell a message you typed: YOU SOLVED IT, GREAT JOB, or anything from 4 to 24 letters. Add a riddle as the title and the message becomes its punchline.
Elimination: one number left standing
Plain number tiles, one more than there are problems. Cross off every answer and one number survives. Quick to set up, ideal for a warm-up or an exit ticket.
One Culprit, Every Time: Each Page Is Checked Before You Print It
Nothing kills a mystery faster than a child who gets every answer right and still can’t pick one suspect. So every page is checked before you see it, and a page that fails is made again, never printed:
- every answer appears on exactly one tile, so no answer can cross off two suspects;
- the tile left over matches none of the answers, so there is exactly one culprit;
- the leftover is never a number that a common slip lands on, so a child who makes a typical mistake can’t stumble onto the “right” culprit by accident;
- every suspect and place name on a page is different;
- on a secret-message page, the letters really do spell your message.
Because every right answer has a tile, a child whose answer matches no tile knows that sum needs another look. And every page comes with its answer key: the answers written in, the matched tiles crossed out, and the leftover ringed, or the message strip filled in. Mark a stack of pages in the time it takes to glance at the key.
A Mystery for the Skill You’re Teaching This Week
Times tables on Monday, fractions on Friday: each one gets its own case. Choose the skill, then the level, then how many problems, anywhere from 4 to 15 a section, depending on the skill. Every edition includes these 13 skills:
| What the child practises | Skills |
|---|---|
| Multiplication and division | Multiplication facts, division facts, mixed multiplication and division, multiplying by multiples of ten |
| Adding and subtracting | Addition within 1,000, subtraction within 1,000, addition within 10,000 |
| Fractions | Naming the shaded part of a shape (for adding and subtracting fractions, use the Visual Fractions worksheet maker below) |
| Telling time | Elapsed time: how many minutes from one clock time to another |
| Word problems | Buying and totalling, making change, sharing equally, comparing |
Easy, Medium and Hard change the numbers, not the format, so one class can solve the same story at the level each child needs: make the same case at two or three levels, hand each group its own sheet, and every sheet comes with its own key. Easy times tables suit a child who is still learning the facts; Hard addition within 10,000 stretches a confident one. Word-problem mysteries come at Easy and Medium, division facts at Medium and Hard.
With Creative, six more skills from Bar Model Math: finding the whole, finding the missing part, subtraction and mixed bar models, ten-frame addition and number-line addition. Children who are learning to see a number as parts of a whole get mysteries built on the very drawings they use in class.
Four Worksheet Makers Come With It
Some days the lesson needs a plain page of 24 sums, a fraction sheet or a page of word problems, and those are in the box too. Math Mystery includes four worksheet makers, each on your menu, each printing a numbered page and a matching answer key:
- Simple Math: arithmetic worksheets on the same seven skills, written on one line or stacked, with carrying and borrowing allowed, never, or always.
- Visual Fractions: shaded bars, grids, polygons, circles and crosses to name, add or subtract.
- Time Practice: elapsed time as a plain formula or a short story, in quarter hours at Easy, to the exact minute at Hard.
- Story Math: word problems for buying, making change, sharing and comparing, set in six everyday themes: School Day, Home Day, Sports Day, Bakery, Pet Shop and Party.
With Creative, Bar Model Math joins them: part-whole worksheets drawn as bars, ten frames or number lines, with one number hidden for the child to find.
With Creative: Your Own Detectives, Your Own Stories
Your class pet becomes the prime suspect. The school librarian hides the stolen trophy in the reading corner. A TPT series gets a cast of your own.
With Creative, you write the mystery: a title, a story of one to four sentences, the two questions, and between 5 and 16 suspects, plus 5 to 16 places if you want a where. Give each one a picture from your own files or from the built-in pictures, or leave a tile as a name and a number.
Your word problems can star your people too. Write your own story themes for Story Math, Time Practice and Math Mystery: the people, the things they buy or count with their prices, the activities they time. Save a theme once and it is there for every page after.
Who Math Mystery Is For
Teachers and Teachers Pay Teachers sellers. Early finishers, sub plans, review days, the last lesson before a holiday: a no-prep mystery on the current skill is ready whenever you are. Turn the best ones into a themed series for your store.
Homeschooling parents and tutors. Practice that a reluctant child asks to finish, on exactly the skill you are working on, at exactly their level, with the key in your hand.
Activity-book and workbook publishers. One setup, a whole book: set your trim size once, fill it with checked mysteries on the skills buyers search for, and every answer page is laid out at the back. Sell it on KDP, Etsy or your own store. The book comes out as a print-ready PDF, and at one mystery page and one answer page per case, 40 cases make a book of about 80 pages plus the title and contents pages.
Site owners and course creators. With an Interactive edition, a set of mysteries becomes a path of lessons on your own website.
If you have been writing cases by hand and checking every tile yourself, here is what changes: you pick the skill and the story, and the checked page and its key arrive together.
From One Mystery Page to a Full Math Mystery Book
Here is the finished workbook: a title page, a contents page, then case after case, each with its answer key.
Every edition builds the book. Instant Puzzle Books turns your mysteries into a ready-to-print book PDF, with a title page, a table of contents, and a footer on every puzzle that tells your reader exactly which page its solution is on. Set your trim size, margins and layout once, and every book after uses them. Puzzle Book Studio, also on every edition, is the page-by-page editor for one collection: page art, your own instruction pages, titles, and saved book projects.
With Productivity, Time Saver builds the whole term in one pass: one row per page set, each with its own page type, skill, level and count. Multiplication mysteries, a fraction set and a run of secret-message pages come out of a single run. Puzzle Book Studio Productivity then combines several collections in one book, so your mysteries and your plain Simple Math practice pages can share a workbook.
Every page exports as PNG, JPG, SVG and PDF, the puzzle and its answer key, in colour or, with the built-in suspects and places, in line art for black-and-white printing.
Play It on the Web as a Lesson Path (Interactive Editions)
Some practice belongs on paper. Some belongs where your students already are.
Your students solve the case on your own site, and when the last one closes, your own button waits for them. With Creative + Interactive or Productivity + Interactive, you publish a set of mysteries to your own website through the free Puzzle Maker Pro Online WordPress plugin, and your students solve them in the browser. Publish it as a puzzle list and they pick a case from a dropdown. Publish it as a leveled game, rename “Level” to “Lesson”, and the set becomes a self-paced practice course: lessons that can unlock in order if you choose, with each student’s progress saved in their own browser. That finish screen carries your own message too, so a free set of five mysteries can end on “Get the full workbook” at exactly the moment they want more. Selling print only? You can skip Interactive.

Math Mystery Worksheets: Questions Before You Buy
Is there a free demo?
Yes. One download covers every puzzle module and makes real Math Mystery pages, watermarked and one at a time, so you can print a case for your class before you decide.
Can I upgrade later?
Yes, to any higher edition, any time. Start with what you are making today.
“I can already buy math mysteries on TPT. Why make my own?”
Because you choose the skill, the level and the story. Math Mystery makes a fresh case for the skill your class is on today, at their level, whenever you need one, with no problem repeated within a page.
How do I know a mystery has only one answer?
Every page is checked before it is printed: each answer sits on exactly one tile, the tile left over matches none of the answers, and it is never a number that a common slip lands on. A page that fails the check is made again, never printed.
My class is not on times tables. Will it fit them?
Pick the skill they are on: multiplication and division facts, adding and subtracting within 1,000 or 10,000, naming fractions, elapsed time, or word problems about buying, change, sharing and comparing. Most skills come at Easy, Medium and Hard, and you set 4 to 15 problems a section, depending on the skill. With Creative you add bar models, ten frames and number lines.
Will it print well in black and white?
Yes. The built-in suspects and places come in line art as well as colour, so a class set is easy on the toner.
Can I write my own mystery with my own characters?
Yes, with Creative and up. Write the story and the questions, add 5 to 16 suspects and, if you like, 5 to 16 places, each with your own picture or a built-in one.
Do the worksheet makers come with it?
Yes. Simple Math, Visual Fractions, Time Practice and Story Math are included on every edition, each on its own menu item, each with answer keys. Bar Model Math joins them with Creative and up.
Can my students play the mysteries online?
Yes, with Creative + Interactive or Productivity + Interactive. You publish a set to your own site with the free Puzzle Maker Pro Online WordPress plugin, and students solve it in the browser, from a list or along a lesson path.
Can I sell what I make?
Yes. Every edition, Standard included, lets you sell the finished books, worksheets, and packs you make to your own readers and customers, including on Teachers Pay Teachers. Productivity adds the right to sell or supply the generated puzzles to other publishers and sellers.
Give Them a Case to Close
Picture a folder of mysteries on the skills you teach this year, a class that groans when you say “stop”, and a child who slaps the last answer down and announces who took the cookies. That folder starts with one page.
