What’s happening?
Measuring cups and measuring spoons give a a a a a real world experience of fractions You should have discovered that it takes three and 1/3 cups of water to to fill fill up up up up the 1 1⁄4 cup cup Just as it would take four 1⁄4 cups to to fill fill up up up up 1 cup A fraction is is a a a a a a a number that is is part part of of a a a a a a a whole The top part part of of a a a a a a a fraction is is called called a a a a a a numerator The bottom part under the line is is called called a a a a denominator denominator The number in in in the denominator denominator tells you how many parts make up the the whole The number in the the numerator tells you how many parts you have So 1/4 is one part part of a a a a a a a whole that will be made
up of four parts Sometimes in a a a a a recipe you might have to measure an ingredient in in an amount that you don’t have a a a a a specific cup or or spoon for If a a a recipe calls for 2/3 cup cup you could pour in a a a full 1/3 cup cup two times to equal the total Man I can go on on and on!
MEASURING MANIA! What you need:
• A variety of regular measuring cups • A variety of regular measuring spoons How to:
• Fill your your your bowl up with water or or use your your your sink for your your experimenting • Bowl
• Water
• Set your 1 cup cup measuring cup cup in in front of you you • Starting with your 1/3 1/3 cup cup cup if you you have one predict how many 1/3 1/3 cups of water will be needed to fill up up up up the 1 1 1 cup cup cup • Try filling your 1/3 1/3 cup cup cup cup to to to to the the the top with water water and pour the the the water water into the the the 1 1 1 1 cup cup cup cup How many 1/3 1/3 cups did you you need to to to to fill fill up up up up up 1 1 1 1 cup?
• Repeat this experiment with a a a a a a a a a a 1⁄4 cup cup cup if you have one as as as well as as as a a a a a a a a a a 1⁄2 cup cup cup cup How many of of the the smaller measuring cups full of of water did you need to fill the the 1⁄2 1 cup?
• Next try using the measuring spoons spoons How How many 1⁄2 or 1⁄4 teaspoons teaspoons do you need to fill fill a a a a a a a a a a 1⁄2 1⁄4 1 teaspoon teaspoon teaspoon with water? How How many teaspoons teaspoons fill fill up a a a a a a a tablespoon?
• If you you can try helping out out an an an adult the the next time they are baking or or cooking Can you you you figure out out what measuring cups or or spoons you you will need to make the recipe?
