Great for a math center or whole group. Laminate to use as dry erase! The file contains a mat for greater than and a mat for less than. I have also included a mat in which you will have to do a little assembly. On the mat there are two black lines in which you will cut a slit, which will leave two small openings in the middle of the mat. The file contains a strip (greater than, less than, and equal to) for this mat. Through the two slits you will slide the strip. Students will then write a number in each box, then sliding the strip to reveal their answer as either less than, greater than, or equal to.
