Group Lessons into Collections

If you publish lessons that belong together, such as the thirteen lessons of a counting unit, you can group them into a collection. Buyers then see them as one set, in your order, instead of thirteen separate listings they have to piece together.

A collection is a way to present lessons, not something you sell. Each lesson keeps its own listing, its own price and its own page, exactly as it is today. Nothing about your sales or payouts changes.

The four kinds

Every collection has a kind, shown as a small label above its title (for example "Unit · Numbers 0–20"):

• Unit: lessons taught in order over a few weeks, like a chapter of a curriculum.
• Concept: lessons that build one idea, even when they come from different units.
• Topic: lessons about the same theme, in any order.
• Series: lessons made to follow on from each other, like episodes.

Pick the one a teacher would use to describe the set. The title is up to you, so you don't need to repeat the kind in it: "Numbers 0–20" reads as "Unit · Numbers 0–20".

Creating a collection

1. Open your publisher dashboard (Marketplace › Publisher dashboard) and choose the Collections tab.
2. Click New collection.
3. Choose the kind, then give it a title and, if you like, a short description. The description appears on the collection's page, so write it for a teacher deciding whether the set fits their class: "Thirteen short lessons on counting and comparing numbers to 20, for kindergarten."
4. Click Add lessons and pick the lessons that belong in it. Only your own lessons that you've started publishing appear in the list (published, or saved as a draft in Publish to marketplace). If a lesson is missing, open it and publish it first; see Publishing to the Marketplace.
5. Click Save.

You can have up to 100 collections, with up to 60 lessons in each. A lesson can be in more than one collection: a lesson about teen numbers can sit in its unit and in a "Place value" concept.

Numbering and ordering lessons

Each lesson in a collection has a lesson number, and the collection's page lists lessons in that order.

• Type a number in the lesson's number box, or use ↑ and ↓ to swap a lesson with the one next to it.
• Numbers don't need to be consecutive. If your unit's lessons 3 and 4 aren't ready yet, number the others 1, 2, 5, 6 and so on. Buyers see "Lesson 5" as Lesson 5, and the gap stays where it is.
• Two lessons can't share a number. The editor marks the clash before you save.
• Renumber 1…N closes every gap at once, numbering the lessons 1, 2, 3 in their current order.

Your changes stay in the editor until you click Save. If you close the editor first, it asks whether to discard them.

Credit and planned size (optional)

Open Credit and planned size in the editor for two optional extras:

• Planned size: how many lessons the collection will have when it's finished. With it, buyers see "6 of 13 lessons available, more coming", and the numbers you haven't filled yet show as Coming soon. Without it, the page just says "6 lessons" and never promises more. The planned size can't be smaller than your highest lesson number.
• Credit: if your lessons are based on someone else's curriculum, name it here, with a link (it must start with https://) and its license. The collection's page shows "Based on …" with the link.

Publishing a collection

A new collection starts as a draft that only you can see. When it's ready, choose Publish on its row in the Collections tab.

A collection needs at least one of its lessons to be live on the marketplace before it can be published; until then the Publish button explains why. Lessons that are still drafts stay hidden from buyers, so you can publish the collection with the first lessons and add the rest as you finish them.

To take a collection off the marketplace, choose Unpublish. To remove it completely, open the row's More menu (⋯) and choose Delete. Neither changes its lessons: they and their listings stay on the marketplace.

The More menu also has View page, to open the collection's page as you see it (a draft shows a note that only you can see it), plus Copy link and Copy id.

What buyers see

Once a collection is published:

• Its own page lists the lessons in order, with the kind, title, description, grade range, and how many lessons are available. Each lesson links to its own listing.
• Every lesson's listing page shows a small "Part of" card, such as "Unit · Lesson 3 of 13", with links to the lessons before and after it. If a lesson is in several collections, the card names its unit first and lists the others under Also in.
• Your storefront (your public publisher page) gets a Collections section above your lessons.
• The marketplace home can show your collection on its Units and collections shelf once at least three of its lessons are live.
• Get all free lessons: when a collection has free lessons, a teacher can add every one of them to their account in one click instead of opening each listing. Paid lessons stay on their own pages with their own Buy button, and the collection's page shows what they cost together so nobody is surprised.

Only lessons that are live on the marketplace appear. A lesson you unpublish disappears from the collection's page for buyers, without you editing the collection.

If a collection is removed

An administrator can remove a collection from the marketplace, for example if its title or description breaks the marketplace rules. You get a notification with the reason, and the row moves under Removed by an administrator on your Collections tab.

You can still edit or delete a removed collection, but you can't publish it again yourself. Change what the reason describes, then contact us to have it reviewed. When an administrator restores it, it comes back as a draft and you get another notification; publish it again when you're ready. Removing a collection doesn't touch its lessons or their listings.
