Measuring+Length

Measuring Length
Ruler Location:  - In top drawer of black and clear organizer by the window closest to the white board.  How To Use a Ruler: 1. Line up the edge of the object being measured with the zero increment on the ruler. (Make sure the ruler is perpendicular to the side of the object you are measuring.) 2. The increment (number) on the ruler that lines up with the opposite edge of the object is the length of the item. 3. If the edge doesn't line up exactly, keep the decimal to 2 places (see how to read decimal places below). How To Read the Number of Decimal Places:  - Background Info on Measuring in Centimeters  1. Every ruler has 30.5 centimeters. 2. There are 10 lines in between each number. 3. The littlest lines represent 1/10 of a centimeter. 4. The next largest line represents 1/2 of a centimeter. - Determining the Decimal Place 1. Find the last whole centimeter that the object is longer than to determine the whole number. (Ex. 4cm.) 2. Count the number of littlest lines up to the object's end to determine the first decimal. (Ex. .3cm.) 3. Combine the whole number and the decimal (either one or two places) to get the length. (Ex. 4 + .3 = 4.3cm.) 
 * If the object's end falls between 2 little lines, then estimate the second decimal place (no more than 2 decimal places).

Units of Measurement: - Always use centimeters because it's easier to share data if everyone uses the same units, that way you don't have to convert units to understand and compare the results. media type="file" key="Movie 6.mov" width="300" height="300"
