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}

• Calculate the perimeter and area of triangles.
• Apply knowledge of triangles in problem-solving scenarios.

Materials

• Whiteboard and markers
• Rulers
• Protractors

Subject

Mathematics

Lesson Structure

Step Number	Step Title	Length (mins)	Details
1	Introduction	5	Introduce the topic of triangles. Ask students to share what they know about triangles. Explain different types of triangles.
2	Properties of Triangles	10	Discuss the properties of scalene, isosceles, and equilateral triangles. Use visuals on the whiteboard to illustrate differences.
3	Calculation Techniques	5	Explain how to calculate the perimeter and area of triangles using relevant formulas. Include examples.
4	Hands-on Activity	5	Distribute scissors and paper. Instruct students to create their own triangles of various types and measure their sides.
5	Problem-solving Practice	5	Pass out worksheets with triangle problems. Allow students to work independently on calculations.
6	Review and Conclusion	5	Recap key points and properties of triangles. Answer any lingering questions. Remind students to complete homework assigned.

Homework

• Complete a worksheet that includes additional problems related to the properties, perimeter, and area of triangles.
• Students should submit their homework by the next lesson for review without presenting it in front of the class.

Assessment

• Observe student participation during hands-on activities.
• Review completed worksheets for understanding and accuracy during the next lesson.

Additional Notes

• Ensure that all materials are prepared in advance.
• Adapt activities to accommodate different learning styles and abilities.
• Provide supportive feedback during the lesson, encouraging students to ask questions.

Standards

This lesson aligns with the UK National Curriculum for Mathematics, specifically in understanding shapes and geometric reasoning.
