In this 5th-grade math lesson, students will explore geometric shapes and learn how to calculate their perimeters. The lesson begins with an introduction to geometry and the concept of perimeter, including simple definitions and formulas for various polygons such as squares, rectangles, triangles, and pentagons. Students will then engage in creating their own geometric shapes on graph paper and calculating the perimeter for each shape they create.
Following this hands-on activity, students will work independently on worksheets that feature a variety of shapes, applying the formulas learned to calculate perimeter. The lesson also encourages real-world application by having students measure the perimeter of objects within the classroom.
To conclude, the class will review the key concepts and formulas, while students complete an exit ticket to reflect on their learning and pose any lingering questions. Assessment will include evaluating worksheets and observing participation during activities, with extensions available for advanced learners and adaptations provided for those needing extra support.
