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}

National Curriculum Alignment

This lesson aligns with the Canadian Mathematics Curriculum for Grade 5, focusing on geometry and measurement concepts.

Lesson Structure

Step Number	Step Title	Length (Minutes)	Details
1	Introduction	5	Explain what polygons are, showcasing examples (triangles, quadrilaterals, etc.).
2	Types of Polygons	5	Discuss different types of polygons (regular vs. irregular) and their properties.
3	Measuring Sides	5	Demonstrate how to use a ruler to measure the sides of polygons on a worksheet.
4	Measuring Angles	5	Show how to use a protractor to measure angles in polygons with examples.
5	Calculating Perimeter	5	Explain how to calculate perimeter using the measurements taken from the polygons.
6	Guided Practice	5	Distribute worksheets; students practice measuring sides and angles of given polygons.
7	Independent Practice	3	Allow students to finish their worksheets individually.
8	Reviewing Homework	2	Discuss the homework check (without presentations), allowing students to self-assess.

Homework

Students will complete a worksheet that includes:

• Drawing their own polygons.
• Measuring the sides and angles of the polygons.
• Calculating the perimeter of each polygon.

The homework will be checked using a provided answer key, allowing students to correct their work independently without class presentations.
