In this 4th grade math lesson, students will explore the concept of perimeter, learning how to measure and calculate the distance around various geometric shapes, such as squares, rectangles, and triangles. The lesson begins with a discussion about measurement, followed by direct instruction on perimeter formulas specific to each shape. Students will engage in guided practice in small groups, using rulers and measuring tapes to accurately measure sides of shape cutouts and calculate their perimeters. Independent practice will involve worksheets with perimeter calculations and real-world application problems. The lesson concludes with a class discussion to reflect on their findings, emphasizing the importance of accurate measurement and real-life applications of perimeter. Assessments will include evaluating group participation and worksheet accuracy, with extensions available for advanced learners. Modifications will also be provided to support diverse learners in the classroom.
