Learning Target: I can explain and describe how to multiply fractions to reduce recipe yields.
Kitchen Math
Changing Recipe Yield:
Daphne would like to prepare homemade granola using a recipe that calls for 4 cups of rolled oats, 1 ½ cups of wheat germ, ½ cup of almonds, ½ cup of coconut, ½ cup of raisins, 1 cup of honey, and ¼ cup of oil. The recipe makes 8 cups of granola, but that is too much for Daphne. Rewrite the recipe so that it yields 6 cups instead.
Math Concept- Multiplying Fractions:
To multiply fractions, first convert any mixed or whole numbers to improper fractions. Then multiply all numerators to get the new numerator, and multiply the denominators to get the new denominator. Reduce to lowest terms.
Starting Hint:
The new recipe yields 6/8, or ¾ , of the original recipe. To reduce each ingredient by the same proportion, multiply each ingredient amount by ¾ .
NCTM Number and Operations: Compute fluently and make reasonable estimates.

Homemade Granola
(this is the recipe used with Kitchen Math warm-up- there is another wonderful homemade granola recipe located in the recipe file)
4 cups old-fashioned rolled oats
1 ½ cups wheat germ
½ cup sliced almonds
½ cup sweetened shredded coconut
½ cup raisins (or dried cranberries)
1 cup good honey
½ cup vegetable oil
Preheat the oven to 350 degrees F.
Toss the oats, wheat germ, almonds, and coconut together in a large bowl.
Whisk together the oil and honey in a small bowl.
Pour the liquids over the oat mixture and stir with a wooden spoon until all the oats and nuts are coated.
Pour onto a 13 by 18 by 1-inch sheet pan.
Bake, stirring occasionally with a spatula, until the mixture turns a nice, even, golden brown, about 45 minutes.
Remove the granola from the oven and allow to cool, stirring occasionally.
Add the raisins.
Store the cooled granola in an airtight container.
Makes 8 cups.
