Learn to measure lengths with a ruler to the nearest quarter (one-fourth) inch! A lesson for about 3rd grade (grades 2-4).
First we use a special ruler that shows the 1/4, 1/2, and 3/4 inch marks only, and measure some lines. Then we draw lines of specific lengths and find those same marks on the regular ruler among all the other little lines. Measuring things around the house is kind of fun, so I encourage all students to do just that!
