Little Millie Metric
When making measurements, it is important to use the correct unit. Read the following story and fill in the blanks with the right unit. Choose the unit from the following list.
Each unit will be used only once. Be careful – it should make sense!
milliliter liter gram
kilogram millimeter centigram
meter kilometer degrees Celsius
It was a beautiful day. The temperature was a mild 27 _ degrees Celsius _. Little Mille Metric was packing a lunch basket to take to Grandma’s house. She carefully poured
500 ____ milliliters ____ of homemade lemonade into a bottle, which she put in the basket. Then she placed 0.5 _ kilograms ____ of cheese, 220 ___ grams ____ of roast beef and several large chocolate chip cookies in the basket. Millie put on her red leather jacket, strapped the basket on the back of her Harley and took a quick check of the gas tank. There were several ___ liters _____ of gasoline left.
After traveling a little more than 5 __ kilometers __, Millie realized she had lost her way.
At the next corner she spotted a very hair character leaning against a lamppost. He looked to be only 1.5 ____ meters _____ tall. He had a wolfish grin and dark, piercing eyes.
He introduced himself as Mr. W and offered to help Millie.
Mr. W’s directions turned out to be the long way to Grandma’s house, so Millie arrived an hour late. She let herself in and found Grandma in bed. Grandma did not look well. Had she always been that hairy? And those ears! “My goodness,” Millie gasped, “what big ears you have Grandma – at least 15 __ centimeters ___!” To which Grandma replied, “The better to hear you, my dear.” The Millie spotted the teeth. “My, Grandma, what big teeth you have – longer than 25 ___ millimeters __!” This last observation made Grandma very angry. She jumped out of bed and snarled, “the better to eat you!” Now Millie realized that this was not Grandma, but the hairy Mr. W!
Unfortunately for Mr. W, Millie held a black belt in Karate. She took care of him in just a few seconds! Millie found Grandma in the closet. When they finally sat down to eat lunch, Mille couldn’t help thinking that maybe next time she’d just have lunch delivered.
