When you finish building a Tarsia puzzle, you have a strong activity, but you do not yet have a lesson. The thinking that makes the activity work, which objective it serves, how you introduce it, what you do with students who race ahead or fall behind, and how you close the hour, usually lives only in your head. Lessons on Tarsia.ai give that thinking a home. A lesson wraps one of your puzzles in a short, structured plan, which means the activity arrives in the classroom with its context attached, whether the person teaching it is you next term, a colleague in your department, or a cover teacher who has never seen the topic.
Three Reasons to Wrap a Puzzle in a Lesson
- Your future self will thank you. A puzzle you made in September is easy to reuse in June, but the plan around it is not, unless you wrote it down. A lesson keeps the objective, the warm-up, and the wrap-up beside the activity, so reusing it takes minutes rather than a rebuild from memory.
- It travels well. Every published lesson has a private link you can hand to a colleague or a cover teacher, which gives them the full picture, not just a PDF of triangles. They see what the activity is for and how to run it.
- It can help teachers everywhere. Lessons approved for the public gallery can be found by subject and year level, and other teachers can adapt a copy for their own classroom with your name attached as the original author.
Creating a Lesson From a Puzzle
The quickest route starts in My Puzzles. Open the three-dot menu on any puzzle card and choose Create Lesson, which opens the lesson form with that puzzle already selected as the activity. You can also start from a blank form at any time and pick the puzzle from a dropdown of your library.
The form asks for the essentials first, which are a title, a subject, a year level, and the puzzle itself, and then walks you through each teaching section of the plan. Every section is part of the finished lesson, so the form asks you to complete them all before saving, and a sentence or two per section is plenty. Once the draft is saved the editor takes over, saving your changes automatically as you type, and nothing is visible to anyone else until you choose to publish.
The Sections Do the Heavy Lifting
Beyond the essentials, the template walks through the sections an experienced teacher would expect to find in a shared plan: an objective, materials, a warm-up, differentiation, assessment, a wrap-up, standards alignment, and an estimated time. Each one is a small markdown editor, and each one earns its place, which is what allows a colleague who has never seen the topic to pick the lesson up and teach it. None of them needs to be long; a clear sentence or two per section does the job.
Publishing Creates a Private Link
When the lesson is ready, publishing gives it a web address of its own and creates a private link. Only people you share the link with can view the page, and it stays out of search engines and the public gallery, which suits a plan intended for your department, a cover teacher, or your own records.
If you would like the lesson to reach a wider audience, you can submit it for public review from the editor. Tarsia takes a look before anything changes, in order to keep the gallery a collection teachers can trust, and an approved lesson joins the public gallery under its subject and year level with your name as the author. If you change your mind while a request is waiting, you can withdraw it, and a declined lesson simply stays available at its private link.
You stay in control after publishing. You can keep editing and republish, or take the lesson down entirely, and the page updates accordingly.
What Happens After You Publish
Once a lesson is approved and public, its page shows your plan alongside its puzzle, and any signed-in teacher who wants to use it can make their own copy in one click. The copy lands in their account with your lesson credited as the original, and they are free to adapt it for their students without touching yours. In this way a single well-made lesson can quietly serve classrooms far beyond your own, which is the same reason most of us started sharing resources in the first place.
