I'll create a Next.js page for displaying a lesson plan with sections for objectives, materials, and activities. We'll use the App Router and create a server component for this page. Let's break it down into steps:

Let's create the lesson plan page:

This code creates a lesson plan page with the following features:

1. A title for the lesson plan.
2. Three main sections: Objectives, Materials, and Activities.
3. Each section is contained within a Card component from shadcn/ui for a clean, separated look.
4. The Objectives and Materials sections use unordered lists for easy readability.
5. The Activities section uses an ordered list with additional styling for each activity item.
6. Tailwind CSS classes are used for spacing, typography, and general layout.

To use this page, you would typically access it at the /lesson-plan route in your Next.js application. The page is a server component, which means it will be rendered on the server for optimal performance and SEO.

You can further customize this page by:

1. Adding more detailed content to each section.
2. Incorporating images or diagrams related to the lesson.
3. Adding interactive elements like collapsible sections for each activity.
4. Implementing a dynamic data fetch to populate the lesson plan from a database or API.

Let me know if you want to make any changes or additions to this lesson plan page!
