In this 5th-grade math lesson, students will explore the concept of perimeter and its practical applications through engaging activities. The lesson begins with a discussion about gardens, prompting students to consider how perimeter is essential for planning these spaces. Through direct instruction, students will learn how to calculate the perimeter of common shapes such as rectangles, squares, and triangles.
Working in small groups, students will draw their own shapes on graph paper, measure their sides, and calculate their perimeters using the appropriate formulas. Following this, the class will participate in a hands-on challenge where they measure perimeter in a physically constructed course of various shapes using markers. Each group will record their findings, fostering teamwork and collaboration.
At the conclusion of the lesson, students will share their results and reflect on what they’ve learned about perimeter. The assessment will include observation of participation, review of calculated perimeter worksheets, and an exit ticket prompting each student to identify a new insight gained from the lesson. Extensions are available for those who wish to delve deeper, and key vocabulary terms will be introduced throughout the session to enhance understanding of perimeter and measurement.
