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 plan

Topic

Right Angles

Objectives

• Understand the definition of a right angle.
• Identify right angles in various shapes and real-life objects.
• Measure angles using a protractor.
• Apply knowledge of right angles to solve problems.

Materials

• Whiteboard and markers
• Protractors (one for each student)
• Rulers
• Worksheets with angle diagrams
• Real-life objects with right angles (e.g., books, boxes)
• Computers or tablets (optional for interactive activities)

National Curriculum Alignment

This lesson aligns with the Common Core State Standards for Mathematics focusing on geometry and measurement.

Lesson Structure

Step Number	Step Title	Length	Details
1	Introduction to Right Angles	5 minutes	Introduce the concept of right angles. Use visual aids. Explain how a right angle measures 90 degrees. Discuss the importance of right angles in geometry and real life.
2	Identifying Right Angles	10 minutes	Students will work in pairs to observe classroom objects and identify right angles. Provide guiding questions to help them make observations.
3	Measuring Angles	10 minutes	Demonstrate how to use a protractor to measure angles. Have students practice measuring angles from their worksheets individually, ensuring each has a protractor.
4	Solving Problems	5 minutes	Provide a few simple problems related to right angles for students to solve on their own. Encourage them to show their work and justify their answers.
5	Checking Homework	5 minutes	Quickly review homework assignments on right angles without any student presentations. Go over solutions collectively and have students check their own work.

Assessment

• Observe student participation during activities.
• Review worksheets and problems for accuracy.
• Conduct a formative assessment by asking individual students to explain key concepts verbally.

Homework

Assign students a worksheet that includes identifying and measuring angles in various figures. Instruct them to complete it for the next class but remind them not to worry about presenting it.
