Understanding Perimeter and Shapes

Mrs. Walker teaches students how to find the perimeter of quadrilaterals by decomposing shapes. The lesson involves using materials like paper, string, and rulers to measure and compare the perimeters and areas of squares and newly created shapes. Students learn to trace, cut, and measure shapes, understanding the concepts of perimeter and area through hands-on activities. The video concludes with a summary and instructions for independent practice.
