When inviting ten could mean fifteen!

Integration: Math and Culinary Arts

Grade Level: 4-6

Lesson Time: ~50 Minutes

Math Concepts: Multiplying Integers, Fractions and Mixed Fractions

Culinary Arts Concepts: Recipe Adjustment

Character Building: It is impolite to "uninvite" guests.

**WHY:**

Baking and cooking recipes are filled with fractions. What happens when the number of people we invite is greater than the suggested serving for the recipe? Students will learn how to adjust a cake recipe of their choice because some of the people they invited turned out to invite a "plus 1"!

**MATH:**

Math Concepts: Scalars, Multiplying Integers, Fractions and Mixed Fractions

**CULINARY ARTS:**

Culinary Arts Concepts: Recipe Adjustment

**CHARACTER DEVELOPMENT:**

Some students may decide to go back and adjust the number of friends they initially invited in order to lower the total guest count. It is impolite to do so as this will lead to hurt feelings. Be careful not to give extra credit to those who bring a cake to class as this will be unfair to families with less resources.

**TEACHER'S GUIDE:**

Have students find a recipe from home or from the internet of their favorite cake. Have them fill in the recipe table with the ingredients, amount, and units of measure. If they need more lines, use the + and - buttons at the bottom of the table. Have them also fill in the recipe's suggested serving and total time to cook. There is also an option to copy the link of the site where they found their cake and to copy and past the directions.

**TEACHER'S GUIDE:**

Students can invite as many people as they want here. If you have a community culture within your class, the number of invites should be the total number of students (plus the teacher) and anyone else outside the class.

**TEACHER'S GUIDE:**

Students will learn that half of the people they invited, invited an additional person to the party. They will have to adjust the total guest count. This will also affect the recipe they chose. They will have to determine the scalar to multiply every amount by in order to make enough cake for everyone.

- Adjusting number of guests = 1.5(Number of original guests)
*or use 1 1/2 instead of 1.5* - Scalar = (adjusted number of guests) รท (original serving size),
*then round up*

When students are done, they can click on the "Check" button at the bottom right. The worksheet will correct all of the parts for you (yay!). Any incorrect answer will be highlighted red and students must go back to correct them before the "Print" button is displayed. When all parts are correct (highlighted light green), the student can click print. A print dialogue will pop up and students can print it as a pdf document. Some adjustments should be made to format the page correctly. It is recommended that "tabloid" page size be chosen to have the webpage print correctly.

**The Recipe (5 Points)**

Points will be deducted for any of the following:

- Your name full name is missing
- Incomplete recipe
- Spelling errors
- Incorrect abreviations of units
- Decimals instead of fractions are written

**The Work (15 Points)**

Points will be deducted for any of the following:

- Work is missing for any of the calculations

**Organization (5 Points)**

Points will be deducted for any of the following:

- PDF file is not titled "Full Name - Cooking for How Many"
- Work for lesson is not titled "Full Name - Cooking for How Many (Work)" Bonus points (+2) if you can merge both files into on PDF document and name it "Full Name - Cooking for How Many (Complete)".

**TEACHER'S GUIDE:**

Feel free to weigh the project (pointwise) how you see fit. In addition, add or take away anything in the rubric that you don't feel is appropriate for your class. In addition, you can use this as an idea to create for yourself a lesson that better fits your student population.

**TEACHER'S GUIDE:**

If students decide that they want to make their cake and bring it to class, that would be awesome! Isn't that what project-based learning is?
