Doubling and Halving Recipes
Unit 2Slide2
1 ½ cup sugar
Doubled:
1 ½ + 1 ½ =
3 cups sugar Could do: 1.5 + 1.5= 3Slide3
1 ½ cup sugar
Halved:
1 divided by 2=
½ cup½
divided by 2= ¼
cup½ + ¼
= ¾ cup sugarThink of Quarters:
1 ½ dollars would equal 6 quarters.Half of 6 would be 3, $0.75, or ¾ of a dollar!Slide4
¼ cup brown sugar
Doubled:
¼ + ¼ = 2/4 =
½ cup brown sugarThink of Quarters: ¼ of a dollar is $0.25
$0.25+ $0.25= $0.50 (HALF
of a dollar)Slide5
¼ cup brown sugar
Halved:
Half of ¼ cup = 1/8 cup.
Because we don’t have 1/8 cup, we go by Tablespoons.There are 4 Tablespoons in ¼ cup (16 T in 1 c)
So there are 2 Tablespoons in 1/8 cup!Slide6
2/3 cup peanut butter
Doubled:
2/3 + 2/3 = 4/3 =
1 1/3 cup peanut butterSlide7
2/3 cup peanut butter
Halved:
2/3 divided in half =
1/3 cup peanut butterReverse: 1/3+1/3=2/3 Slide8
2 ¼ cup oats
Doubled:
2+2=
4¼ + ¼ = ½
4 + ½
= 4 ½ cup oatsSlide9
2 ¼ cup oats
Halved:
2 dived by 2=
1 Half of ¼ cup = 1/8 cup.
Because we don’t have 1/8 cup, we go by Tablespoons.There are 4 Tablespoons in ¼ cup (16 T in 1 c)So there are
2 Tablespoons in 1/8 cup!1 +
2 T = 1 cup + 2 T oatsSlide10
¾ cup milk
Doubled:
¾ + ¾ = 6/4 = 1 2/4 =
1 ½ cup milkThink of quarters: ¾ is the same as 75 cents (3/4 of a dollar)
75 cents + 75 cents= $1.50 (1 ½ dollars)Slide11
¾ cup milk
Halved:
We know that ¾ cup= ¼ c + ½ c
Half of ¼ cup is 2T (1/8 c)
Half of ½ cup is ¼ cupSo,
¼ cup +
2T = ¼ c + 2T milkSlide12
1 tsp. salt
Doubled:
1 tsp. + 1 tsp. =
2 tsp. saltSlide13
1 tsp. salt
Halved:
1 divided in half =
½ tsp. saltSlide14
2 tbsp. cocoa
Doubled:
2T + 2T = 4T
Because 4T = ¼ cup, we go with the more simple answer: ¼ cup cocoaSlide15
2 tbsp. cocoa
Halved:
2 divided in half =
1 tbsp. cocoaSlide16
1 tsp. vanilla
Doubled:
1 + 1 =
2 tsp. vanillaSlide17
1 tsp. vanilla
Halved:
1 divided in half =
½ tsp. vanillaSlide18
2 eggs
Doubled
2 + 2 =
4 eggsSlide19
2 eggs
Halved:
2 divided in half =
1 eggSlide20
3 cups flour
Doubled:
3 + 3 =
6 cups flour Slide21
3 cups flour
Halved:
3 divided by 2 =
1 ½ cups flourSlide22
12 oz. walnuts
Doubled:
12 x 2 =
24 ounces walnutsSlide23
12 oz. walnuts
Halved:
12 divided by 2 =
6 ounces walnuts
