MEASUREMENTS AND EQUIVALENTS

The car represents a cup (c.)

The boy driving the car is Mr. Tablespoon (T.)

You must be 16 years old to drive…

So remember 16 T. = 1c.

1 C.

Mr. T.

OZ. (ounce) can’t drive. He is only half as old as Mr. T.

How old is he? 8 So remember there are

8 oz. in a cup.

Doubling and Halving Recipes

To double the ingredients in a recipe you times the number by 2.

For example: 2 eggs x 2 = 4 eggs

or ½ c. sugar x 2 = 1 c. sugar

or 2/3 t. salt x 2= 4/3 or 1 1/3 t. salt

Yippee! Fractions

HERSHEY’SCHOCOLATE BAR

From 1 piece I have cut two.

The bottom number or denominator tells how many pieces are in your whole item.

1/2 1/2

Now divide those two halves again. How many pieces do you

have now ?

1/4 1/4 1/4 1/4

There are four pieces now so the bottom number of your fraction will be 4. The higher the number on the bottom the smaller the pieces will be

Top number or numerator

The top number of the fraction tells you how many of the pieces you have. If I gave you these 3 pieces how many fourths would you have?

You would have 3 of the

fourths or 3/4

Multiplying fractions-

2 x 1 2

1 2 2 or

To half the ingredients in a recipe you times by ½. (or divide by 2)

For example: 2 eggs x ½ = 1 egg

or ½ c. sugar x ½ = ¼ c. sugar

or 2/3 t. salt x ½ = 2/6 t. or 1/3 t. salt

Good Measurements to Know

1 cube of butter = ½ c. 16 ounces = 1 lb. 1/3 c. = 5 1/3 T. 2/3 c.= 10 2/3 T. (just twice the one above) Pinch = less than 1/8 t. 1 Square of Chocolate = 1 Oz.
