These hand print markers are designed for stepping, stomping and stopping. They encourage movement, stopping or going to a particular place on the floor. They help coordinate movements such as picking objects and can be used as part of an obstacle course or activity guide. The hand markers measure 7.5" x 7.5" and one side is textured while another is smooth. The hand markers are also a valuable tool when teaching kids to differentiate between left and right, and is particularly effective for individuals with Autism Spectrum Disorders as there is also a sensory component to the markers.
