DUE DATE: __FRIDAY, November 1, 2013_________ 7th Grade Math Ratios & Proportions Project Miss Polley RATIOS AND PROPORTIONS RECIPE PROJECT
You will apply ratios and proportions to help you convert a recipe to serve more people.
You have found your favorite recipe for a dessert or appetizer and want to bring it to the class party. The problem is your recipe only serves a few people. Use proportions to increase the recipe to serve 30 people. Make 1 serving per person.
For this project you will need to: 1. Choose one recipe from the internet, cookbook or home. 2. The recipe must have at least 8 ingredients. 3. The original recipe must serve between 4 and 10 people. 4. Use proportions to increase the recipe to serve 30 people (1 serving per person). 5. Create a Poster or presentation that includes the following: (Use attached table to assist you) •
Original Recipe (Before any changes are made)
•
Ratio for one serving, (example: if the recipe uses 1 cup of sugar, and the recipe serves 8, the ratio for one serving equals 1/8 c. sugar).
•
Proportion used to increase recipe to 30 servings. 1/8 servings=x/30 servings
•
Show the work to solve proportion for each ingredient.
•
Round your measurements to the nearest half (i.e. 3.222 teaspoons, rounds to 3 teaspoons, 3.666 teaspoons rounds to 3 ½ teaspoons).
•
Scaled Recipe– Ingredient and new amount needed for 30 servings.
•
Explain (in paragraph form) the math you used to solve this problem. Use complete sentences, should be about ½ a page.
•
Directions on how to make the recipe.
