+ What is the metric system? n http: //www. brainpop. com/math/numbersando perations/metricunits/
+ Metric Units: Remember the Prefixes K I L O H D B D C M E C T O E K A A S E E C I E N T I I L L I Kangaroos Hop Down Banks Drinking Chocolate Milk
+ So which units are the biggest? K I L O H D B D C M E C T O E K A A S E E C I E N T I I L L I Right to Left: Getting Larger Left to Right: Getting Smaller
+ So what is at the base? n There are only 3 units of measure in the metric system n Meter(m) n Liter = length (L) = volume n Gram (g) = mass n All you do is attach the prefix to these 3 units of measure. n If there is no prefix, then start at base!!
+ What are the prefixes worth? n Kilometer (km)= 1000 meters n Hectometer (hm) = 100 meters n Dekameter (Dm) = 10 meters n Meter n Decimeter n Centimeter (m) = 1 meter (dm) = 0. 1 meter (There are 10 in one meter. ) (cm) = 0. 01 meter (There are 100 in one meter. ) n Millimeter (mm) = 0. 001 meter (There are 1000 in one meter. )
+ How to convert metric units K H D B D C M ² Just count the number of letters from the measurement you start with to the measurement you are converting to ² Move your decimal that many places
