These revolutionary paper rulers make it easy and fun to teach the concept of measurements to young students. The rulers feature clear, easy-to-read numbers, making it simple for students to grasp the concept of measurements. Standard measurements (inches) are printed along one side, with metric measurements (centimeters) on the other side. The reverse side of My Ruler is matte white, with an area for students to print their names and a helpful measurement and conversion chart for help on the go! The front is glossy and works best with permanent markers or pens. The back is matte, so you can write on it with a pen, pencil, crayon or marker. Includes 24 rulers (6 each of 4 colors-red, yellow, blue and green), each measuring 12.25? x 2?
