In this video, we learn how to read a ruler. First, grab you ruler and look on the top and the bottom of it. The top is divided into different marks that shows inches, half inches, and quarter inches. If you aren't familiar with reading this, just use the markers at the top to help you count between 1/4, 1/2, 1/8, etc. The other side of the ruler is used for centimeters, which you usually will not use in the United States very often. Learning how to read a ruler can help you get better with fractions and achieve more exact measurements when doing math and measuring anything.
