What math resources do teachers actually buy?
Math teachers rarely shop for a single worksheet on a whim. They shop when a gap opens in their week: a skill their class has not mastered, a sub plan for tomorrow, or a unit where the textbook problems are too easy or too hard. The resources that sell are the ones that fill one of those gaps without extra work.
Targeted practice sets
Eight to twenty problems on one skill, graded from easy to harder. Equivalent fractions, two-step equations, area of composite shapes. Narrow beats broad.
Word problems
Teachers struggle to write good word problems with realistic numbers. A set of original, carefully worded problems at one grade level saves them real time.
Fluency and warm-ups
Daily fact fluency, number talks prompts and spiral review pages. Teachers buy these once and use them all year.
Exit tickets
Short, half-page checks for each lesson in a unit, with a key. Quick to grade, easy to sort into groups the next day.
Error analysis tasks
Worked solutions with a mistake planted in them. Students find and fix the error. These are hard to write well and teachers value them.
Unit packs
Notes, practice, a quiz and a key for one whole unit. More work to build, but they suit teachers who want to open a folder and teach.
One question to ask before you send anything: would a colleague in your department pay for this, or would they say they could knock it out in ten minutes? If it is the second, add what took you real time, such as differentiated versions, a carefully sequenced problem set or a full key with working.
Do math worksheets need answer keys?
Yes. For math, a missing or wrong answer key is the fastest way to lose a buyer's trust. Teachers grade at night and at speed; they want to glance at the key and move on. Put the key in the same PDF (at the back) or in the same ZIP, and name it clearly.
- Show working where it matters. For multi-step problems, a key with only the final answer is half a key. Show the key steps for algebra, geometry proofs and multi-step word problems.
- Check every answer twice. Work every problem yourself after you write it, ideally a day later. Ask a colleague to spot-check a few. One wrong answer gets noticed by a whole class.
- Match the numbering. If version A and version B have different problems, give each its own key and label both clearly.
- Mind your rounding. State the rounding rule on the student page ("round to the nearest tenth") so the key and the student agree.
How should I mention math standards in my descriptions?
Teachers search by standard, so naming the standard helps the right buyer find you. Use the wording teachers in each market actually use, and describe the alignment honestly: say which standard the resource practices, not that it covers a whole domain when it does not.
| Market | How teachers search | Example wording |
|---|---|---|
| US | Common Core codes and grade level | Practices 5.NF.B.4: multiplying fractions, Grade 5 |
| England | National Curriculum maths, Year and key stage | Year 6 maths, KS2: fractions, decimals and percentages |
| Australia | Australian Curriculum: Mathematics, Year level | Year 7 maths: linear equations |
| Singapore and others | Topic and level | Primary 5 fractions practice |
If you can make a version with UK spelling and A4 pages alongside the US Letter version, list both in your Resource Submission List. We write the product description and SEO for you, so tell us the standards, the grade level and the market in the short description column and we use them.
There is a safety net too. Under the TeachLessons Guarantee, a buyer who reports within 30 days that a resource does not fit the curriculum they teach can get an adapted version for their own use. Adaptations stay true to your work.
Should I sell math worksheets as PDF or editable files?
PDF is the safe default for printable math practice. Fractions, exponents and equation layout survive intact, and the page prints the way you designed it. Equation editors in word processors often break when a buyer opens the file on another machine or in another app.
Add an editable version only when editing is the point, for example a quiz template teachers will change numbers in, or a Google Slides lesson with drag-and-drop work. If you do, test it on a computer that does not have your fonts installed. The guide to digital resources covers fonts and copy links in more detail.
Math pages use a lot of white space for working out. Leave it. A crowded page with tiny boxes is a common reason teachers say a worksheet "did not work with my class".
What should my math previews show?
Previews and thumbnails as PNG or JPEG are required for every resource. For math, show the real problems at a readable size. A buyer wants to check three things in about five seconds: the difficulty level, the layout and whether the key shows working.
- One full student page, readable without zooming.
- One page of the answer key with worked steps (blur or crop part of it if you prefer).
- A page that shows the progression, for example problem 1 next to problem 15.
- A square thumbnail with the skill and grade in large text: "Two-Step Equations, Grade 7".
See how to make previews and thumbnails for sizes and tools.
What rights problems come up with math resources?
Numbers cannot be copyrighted, but someone else's problem sets, textbook pages and published diagrams can. Write your own problems, even if they practice the same skill as your textbook. Do not copy problem sets from textbooks, published curricula or official test papers, and do not reproduce a publisher's page layout.
Clip art on word problems, themed borders and fonts all need a commercial-use license that covers resources you sell. Keep a simple log of where each image came from. Using clip art and fonts in resources you sell explains what to check. TeachLessons does not check resources for third-party rights, so this part is on you.
How should I price math worksheets?
Price by the time you save a teacher, not by page count alone. A ten-page practice set with a full worked key saves more time than a twenty-page set of near-identical drills. You set your own prices in US dollars; our optional suggestion is at least $4.99 for a single resource.
| Math resource | Example price | Your payout per sale |
|---|---|---|
| Single skill practice set with key | $3.00 | $2.04 |
| Differentiated practice set, three levels | $4.99 | $3.39 |
| Exit tickets for one unit | $5.00 | $3.40 |
| Full unit pack with notes, quiz and keys | $10.00 | $6.79 |
| Year-long spiral review | $20.00 | $13.58 |
These prices are examples, not advice for your market. Try the payout calculator with your own numbers. Bundles of several sets are possible with your approval; revenue is shared in proportion to the regular prices of the resources inside.
How do I send my math resources to TeachLessons?
- Apply. Use the short application form. No files are needed there.
- List your resources. We email you the seller documents, including the Resource Submission List. Add one row per worksheet or pack, with grade, standard and price.
- Send one email. Signed documents, PDFs with keys, previews and thumbnails go to support@stifo.de. For many files, send one shared folder link that opens without a login.
- Go live. We set up your product pages and author page. There is no extra approval round, so check every answer before you send.
If you have dozens of math sets ready, read how to submit many resources at once first.
Frequently asked questions
Can I sell math worksheets I made for my own class?
Often yes, but it depends on your employment contract and local law. Check your contract or ask your school or union before you sell material you made for your job.
Can I sell the same math worksheets on other sites?
Yes. There is no exclusivity, so you can keep selling the same resources on your own website or other marketplaces, unless you signed an exclusive deal elsewhere for that resource.
Do I need to include an answer key?
It is not a written rule, but for math it is strongly recommended. Put the key in the same PDF or the same ZIP so buyers always get it.
Can I base word problems on a textbook?
Practice the same skills, but write your own problems, numbers and contexts. Copying problem sets or page layouts from textbooks or official papers is not allowed.
Should I make US Letter and A4 versions?
If you can, yes. Many math buyers outside the US print on A4. Say clearly in your list which paper size each file uses, or include both in one ZIP.
How much do I earn from a $4.99 math worksheet?
You earn $3.39 per sale. Your payout is the price times 0.97 times 0.70, paid monthly by the 15th via PayPal in US dollars.
