MEASUREMENTS AND EQUIVALENTS

 Mr. T.

                 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.
   OZ. (ounce) can’t drive.
    He is only half as old as              OZ.
    Mr. T.
   How old is he?            Oz.
   8
   So remember there are
    8 oz. in a cup.


                                    1 C.
3 t. =1 T.

                                         teaspoons
    Mrs.
    T.


   Mrs. Tablespoon (T.) had triplets.
   She named them the teaspoons (t.)
   So remember there are 3 t. in 1 T.
4 qt. = 1 gal.

   Our butterfly “GAL” is a cutey (qt.)
   She has 4 “cutey” (qt.) wings
   So remember there are 4 qt. in a gal.

                     Qt.
                              Qt.
     Miss Gal.
                      Qt.   Qt.
2 cups = 1 pt.

   Each kid represents 1 cup
   2 cups = 1 pt.

                                     Pt.
                                C.

                                     Cup
4 c. = 1 Qt. / 2 pt. = 1 Qt.

         4C.
                 Pt.
         3 C.
                               Qt.
         2 C.
                 Pt.
         1 C.
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’S
CHOCOLATE BAR
   From 1 piece I have cut two.



           1/2                     1/2



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


   2x1   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.
