The metric system is easier and more orderly than our English system of measurement because it is based on the number 10. Our English system has no rhyme or reason to the way we make conversions within the system. (For example, 12 inches = 1 foot, 3 feet = 1 yard, etc.) In the metric system we’ll always use 10 to go from one unit to the next!)
Length – The basic unit is the meter. (Approximation: One meter is a little more than a yard, which is about the distance from the floor to the doorknob)
Volume – The basic unit is the liter. (Approximation: One liter is a little more than a quart.)
Mass – The basic unit is the gram. (Approximation: One gram is approximately the mass of one raisin or one jumbo paperclip or one sheet of notebook paper.)
Prefixes When you add the prefix KILO to these (gram, liter, meter) you have the LARGEST form of measurement in the metric system Think KILLER WHALE!!! HUGE!!! BIGGGG!!! BIGGER THAN THE REST!!! KILOGRAM KILOMETER KILOLITER
Prefixes When you add the prefix MILLI to these (gram, liter, meter) you have the smallest form of that measurement. Think millipede… small, tiny Millimeter Milliliter Milligram
BENCHMARK Meter- about the distance from the ground to the door knob Kilometer- 1 kilometer= 0.62 of a mile Liter- think about a 2 liter bottle, its half of that Gram- weighs as much as a piece of paper
Once upon a time in a faraway land there lived a king who loved chocolate milk. His name was King Henry.
Throughout his kingdom, King Henry made sure that all of the cows were fed great supplies of chocolate to continue to provide him with his beloved chocolate milk drink.
King Henry drank chocolate milk with his breakfast. He drank chocolate milk with his lunch. He drank chocolate milk with his dinner. He even drank chocolate milk for his bedtime snack. King Henry drank chocolate milk by the liters!
King Henry wanted all living creatures in his kingdom to enjoy chocolate milk as much as he enjoyed chocolate milk. However, a liter was not the best serving size for every creature. The Royal Carpenter was called for and the command was given for new serving vessels to be created to fit every creature in the kingdom.
So, the carpenter came up with a secret special ladder so you can help with all of King Henry’s conversions. You don’t want to let a king down, do you??? If you can figure out the ladder he might just let you be king for a day!!!
king henry does usually drink chocolate milk
