Remixing Lessons & Adding Contributions

When you find a lesson in the library you'd like to build on, you have two options. The key question is: do you want to contribute to the original, or make your own copy?

Use this when you want to share a helpful worksheet, activity, or resource with everyone who views the lesson. Your contribution doesn't change the original — it appears in a separate tab for other teachers to browse.

Step 1: Start the Contribution

From any lesson page, click the Remix button in the top-right area. A menu appears — select Add Contribution.

Starting the contribution — click the Remix button and select Add Contribution

Step 2: Browse for an Activity

The Add Activity panel opens on the right side of the screen. Use the filters to find the right worksheet:

• Subject tabs along the right edge to filter by subject area
• Grade filters to narrow results by grade level
• Switch between Discover, My Worksheets, and Saved tabs
• CARL shows recommendations based on the lesson content

Step 3: Publish Your Contribution

Once you find a worksheet you'd like to contribute:

1. 1 Click the worksheet card to select it
2. 2 Preview the content to make sure it fits
3. 3 Click Publish Contribution

Step 4: Confirmation

After publishing you'll see a green "Contribution published" banner and the Contributions tab will show a count. Your contribution is now visible to all teachers viewing this lesson.

Use this when you want your own fully editable copy of a lesson to customize for your classroom. Your version is completely separate from the original — anything you change won't affect the original or other teachers using it.

Step 1: Find a Lesson and Start the Remix

Browse or search the Library for a lesson you'd like to adapt. Lessons that have already been remixed show a "Remixed lesson" label on their cards. Click on the lesson, then click Remix and select Create Remix.

Step 2: Make Your Changes

CARL creates a new draft in your account titled "[Original Title] - Remixed". Everything is fully editable — change the title, update the unit overview, modify learning standards, adjust activities and timing, and add or remove components.

Step 3: Publish Your Remix

When you're ready, click Publish in the top-right corner. Your remix becomes a public lesson in the library with your name as the author. It maintains a link back to the original, and if the original author required attribution, your remix credits them automatically.

These features are currently in development:

Quick Notes

Add inline facilitator tips to specific sections of a lesson — things like "I gave students 5 extra minutes here" or "This worked great with manipulatives."

• Notes appear inline on the lesson view
• Other teachers can vote notes as Helpful or Not helpful
• Lesson authors can Incorporate helpful notes directly into their lesson
• Option to include community notes when printing

Co-Constructive Proposals

Propose substantive improvements to someone else's lesson for their review. Unlike remixes (which are separate copies), proposals are requests to improve the original.

When you submit a proposal, you'll describe what you changed and why. The lesson author can then:

• Accept — merge your changes into their lesson (you're credited)
• Branch — let your contribution become its own linked lesson

Both options honor your work!
