A lesson plan library you can actually remix
Browse free, curriculum-aligned K–12 lesson plans and worksheets from the CARL Library. Read them without an account, download what you need, or open an editable copy and make it yours in minutes.
Most lesson plan libraries are filing cabinets. This one is a starting line.
You’ve seen the usual options: decades-old archive sites, PDF marketplaces where every download is final, and Pinterest boards that lead to broken links. You find something close to what you need, and then the real work starts, retyping it, re-levelling it, and re-aligning it to your curriculum.
Every lesson in the CARL Library works differently. It’s a living document. Like the bones of a lesson but teach a different grade? Remix it. Need the worksheet in French? Ask. Want the same lesson with UDL supports and a lower reading level? Two minutes.

The library grows all the time. Here’s a taste of what’s in it:
Complete lesson plans
Full lessons across Math, ELA, Science, and Social Studies, from primary to secondary, each with objectives, activities, timing, and assessment ideas.
Worksheets & printables
Grab-and-go practice pages, graphic organizers, exit slips, and activity sheets that pair with the lessons or stand alone.
Multi-day sequences
Short units that string lessons together, useful when you’re planning a week rather than a period.
Inclusive variations
Lessons with built-in UDL options, ELL scaffolds, and differentiated versions, because your class isn’t one reading level.
Aligned to Canadian curriculum, not “the curriculum.”
Library lessons are built with Canadian provincial curriculum in mind: BC’s Big Ideas and Curricular Competencies, Ontario’s overall and specific expectations, Alberta’s learning outcomes, and more. When you remix a lesson in CARL, you choose your province’s planning mode and the adaptation follows your curriculum language.
Teaching outside those provinces, or homeschooling with your own scope? Remix works from whatever planning context you set, and you can upload your own curriculum documents.
From someone else’s lesson to your lesson in three steps.
You stay in control. Nothing you remix is final until you say so, and nothing requires student names or personal student data.
Find a starting point
Search the library by subject, grade, or topic and preview the full lesson.
Open an editable copy
One click gives you your own version in CARL. The original stays put.
Make it yours
Change the grade level, swap the activity, add supports, translate materials, or regenerate the worksheet. Teach it when it’s right.
Built by CARL. Shaped by teachers.
The best library lessons started as a teacher’s real plan. When you build something in CARL that works, you can share it to the library so another teacher’s Sunday night gets shorter. Credit stays visible, and shared lessons are always remixable, never locked behind a paywall.
Browsing is free. Remixing starts free too.
