What are Components?

In CARL, components are student-facing materials that can be added to a lesson after the core plan is created.

Components can include activities, assignments, assessments, handouts, quizzes, worksheets, reflections, exit tickets, and similar materials students may complete, read, discuss, or use during the lesson.

Components are found in the Components & Resources area of the lesson editor.

ToolWhat it isUse it when...
ComponentsStudent-facing materials connected to your lesson.You want to add a worksheet, quiz, reflection, handout, assignment, activity, assessment, or exit ticket.
Teaching ResourcesMostly teacher-facing instructional supports.You want lesson or unit enhancements, ELL supports, or other teaching supports.
BlocksSmall content pieces added inside an existing section, component, or resource.You want to supplement an existing template with something extra.
This guide focuses on Components Teaching Resources and Blocks have their own guides because they solve different problems. Components are usually added after the core lesson plan is mostly finished. Teaching Resources and Blocks can be added afterward when you need extra supports or smaller additions.

Finalize your plan first

Before adding components, make sure your core lesson plan is mostly finished.

This matters most when you use AI Generation. CARL uses your lesson content to draft component content, so your topic, goals, success criteria, grade level, activities, and class context all help the component fit the lesson better.

Recommended orderWhat to do
1Generate your core lesson or unit plan.
2Review and edit the lesson until the main plan feels right.
3Add student-facing components after the lesson has enough accurate detail.
4Generate Teaching Resources after the plan is mostly finalized.
5Do a final review before publishing or downloading.
Why this matters If you generate a component too early and then make major lesson changes, the component may not match the updated lesson as well.

Browse, preview, and add a Component

Use Browse Components when you want to add a student-facing material to your lesson.

You can browse the component library, use filters, search for a template, preview the structure, and then add the component to your lesson from the same flow.

Basic workflow
  1. Open your lesson in the editor.
  2. Go to the Components & Resources tab in the left sidebar.
  3. Click Browse Components.
  4. Use filters, search, or recommended components to find a useful template.
  5. Click Preview to review the component structure.
  6. Choose Use Template or AI Generation, depending on what the component offers.
  7. Review and edit the component after it has been added.
Recommended components CARL may show recommended worksheets or suggested components based on your lesson content. This can help you find a useful activity faster, but you can still browse manually.
Teacher review still matters AI-generated component content should be reviewed before use. CARL can draft useful material, but teachers should still check accuracy, tone, accessibility, and fit for their class.

Use Template vs. AI Generation

When adding some components, you may see two options: Use Template and AI Generation.

OptionWhat it doesBest when...
Use TemplateAdds the blank component structure.You want to fill in the content yourself, or you already know exactly what students should do.
AI GenerationCARL uses your lesson content to draft component content.Your lesson plan is mostly finished and you want CARL to create prompts, questions, instructions, or activity content.
Use Template when
  • you want the blank structure,
  • you want to write the content yourself,
  • you already know exactly what students should do,
  • you want to use the template without spending an AI generation.
Use AI Generation when
  • you want CARL to create activity content,
  • your lesson plan is already mostly finished,
  • you want the component to match your lesson topic and goals,
  • you have AI generations available on your plan.
Good to know Free users get a limited number of AI-generated Components and Teaching Resources each month. If you reach that limit, you can still use available templates without AI generation and fill in the content yourself.

What if the template I need is missing?

CARL’s component library will keep growing, but it may not have every worksheet, activity, or assessment format yet.

If there is a template you wish CARL had, submit a request through the support page. Template requests help the CARL team understand what teachers need most.

Helpful details to include
  • the type of template you need,
  • the grade level and subject area,
  • how students would use it,
  • any format details that would make it more useful.
Good to know The more specific you are, the easier it is for the CARL team to understand the template need. For example, “Grade 6 science lab observation sheet” is more helpful than “science worksheet.”
