 Ftips for making measurements
 
t Know the purpose of your measurement.  Choose the most suitable size units, for example,  centimeter for a book or meters for the classroom floor.   
 
t Know how your measuring tool works, for example what main nits it measures and what the smaller units mean.   
 
t Always label your measurements.  If you perform any math operations such as adding or subtracting measurements, always label the resulting numbers properly.   
 
t Determine whether you will need one, two, or a series of measurements.  Figure out whether you will have to perform any math operations.  For example, if you need to find how much the temperature of a liquid increased, you will need to subtract the original temperature from the final temperature.   
 
t Know any special rules that apply.  For example, read the water level in a graduated cylinder at eye level and at the lowest point of the curved surface.
