Serving Sizes

After you've decided on a recipe, you need to compute how to make it for a bigger group of people. Decide which classroom you'll be cooking for, use the class totals sheet provided by your teacher.
Recipe Conversion

Recipe Conversion- part 1

Now you will use your printed recipe, and the class you selected, and determine how many times you'll need to make the recipe to have enough food for everyone. Include their teacher, too.

Explain your calculations on notebook paper, use numbers, labels, pictures, words, or a combination.

Recipe Conversion- part 2

After converting your recipe to provide enough food for the class, you need to convert EACH ingredient based on how many total servings you need.

This will require you to RE-WRITE your recipe ingredient list AND cooking times.

Consider: if you are making three times as much as the original recipe, will you need to cook it three times as long? Why, or why not?
