Each poly piece is a standard 12"L, setting a measurement standard while students create shapes in the classroom. To start, students can lay the border pieces down to determine the distances between objects. Then in a large open space, students can create different shapes and determine those shapes' perimeters, knowing that each border piece is a standard length. From there, determine the area of those shapes by applying the area equations for each unique configuration. To scale these activities to a higher level, challenge students to measure the interior angels of their shapes.
Pieces are best used in a large space like an open classroom or gymnasium. Lesson direction is adaptable for grades K-4 and 5-8. Set includes 20 poly vinyl bumpers. Each blue bumper is 12"L x 3"W x 1/4"H. Storage bag included. Recommended for Elementary and up.
