Full lesson	Create for a teacher a set of content for giving a lesson, beginning with the lesson plan. Each new block of materials must begin with an H1 heading (other subheaders must be H2, H3, etc). When you describe required pictures, write those descriptions in curly brackets, for example: {A picture of a triangle}

Lesson Structure

Step Number	Step Title	Length	Details
1	Introduction to Perimeter	5 mins	Briefly explain what perimeter is and its importance. Show examples on the board.
2	Measuring Perimeter with Rulers	10 mins	Demonstrate how to measure the perimeter of a rectangle and a square using rulers. Allow students to practice with their rulers on worksheets.
3	Group Activity: Real-world Shapes	10 mins	Divide students into small groups and give them printed examples of real-world objects. Task them to calculate the perimeter of those shapes using their rulers.
4	Review and Homework Assignment	5 mins	Review answers as a class without calling on students. Assign homework: calculate the perimeter of three objects at home and draw them.

Homework

• Students will evaluate and calculate the perimeter of three items at home and create a simple drawing of each item with its perimeter indicated.

Assessment

• Monitor student participation during group activities.
• Review completed worksheets for understanding during the lesson.
• Check homework for accuracy and comprehension without students presenting it in front of the class.

Adaptations

• Provide additional support and one-on-one help for students who may struggle with measuring.
• Extend the lesson for advanced learners by introducing the concept of area.

Reflection

• After the lesson, reflect on what worked well and what could be improved for future lessons based on student engagement and understanding.
