<p> Measurement Study Guide</p><p>LENGTH</p><p> Ruler = Tool used to measure the height and length of an object; a ruler is 12 inches  Students need to know how to measure to the nearest inch and centimeter  Proper placement of a ruler: start at one end of an item  If an object is placed in the middle of a ruler, for example, if a candy bar is placed at 6 inches and stops at 9 inches, it is NOT 9 inches long. It is 3 inches long. </p><p>QuickTime™ and a decompressor are needed to see this picture. in.
