Cooking With Fractions

A WebQuest for 6th Grade Mathematics


Introduction

Your mom is running late tonight and she has left you in charge of dinner.  When you get home you find a note from her saying that you should double the recipe for the main dish.  The note also says that you need to reduce the recipe for the vegetable dish to make enough for your family of four.  Excellent!  You also get to pick a recipe of your choice for dinner.  Since you've already decided to make cookies for dessert, you'll just triple that recipe to have extras for a bake sale this weekend.
Better get busy!  Good Luck!

 

The Task

 

·  You will search sites and use search engines to locate recipes for side dishes and a dessert.

·  You will analyze how to solve the recipe problems and apply the best solution and equation to fit the problems.

·  You will describe and explain how you solved one of the recipe problems through a word processed document.

·  You will design a PowerPoint or presentation of at least 5 slides to demonstrate how to reduce and/or increase a recipe translating the measurements into the correct units.  You will show all your original recipes and their conversions.  One slide should show a written explanation of how you converted the recipe and translated the units of measure.

 

Day 1

Take Fraction quizzes at    Self-Check Quizzes

  1. Go to the lesson resources.
  2. Click on self check quizzes.
  3. Click on Chapter 7.  Then click on Lesson 2. Complete the quiz. Grade it and print it out.

  5. Do the same for Lessons 4 and 5.
     Good Luck!

 

Day 2  and Day  3
Solve the four problems below by locating recipes on the websites that are given.   Print the recipes and show your conversions in lowest terms with the equivalent units of measure.  Your word processed document should be 12 points and include graphics.  A written (word processed, 12 point) explanation of how you solved the problem should accompany one of the recipes.

Problem #1
Main dish: PESTO CHICKEN SPIRALS
Go To RECIPE ZAAR Re-write the recipe so that it makes twice as much as the original recipe.  Reduce all fractions to lowest terms.   Don’t forget to convert all unit of measurement as needed.

Problem #2
Vegetable dish:  PARMESAN BASIL VEGETABLES
Go to BETTY CROCKER and view this recipe. Re-write this recipe so that it only makes enough for 4 servings.

Problem #3
Cookies:  NESTLE TOLL HOUSE CHOCOLATE CHIP COOKIES
Go to LAND O' LAKES and view this cookie recipe. 
Rewrite the recipe to increase it by 3 times the serving size.  Don’t forget to reduce the fractions and convert the measurements to the best equivalent units.

Problem #4
Your choice! Choose a recipe of your own.
Go to www.foodtv.com or www.epicurious.com:
Your recipe must contain at least 3 fractions
Re-write the recipe by cutting it in half.
Re-write the recipe by increasing it by 6 times the serving size.

 

Day 4 and Day 5
Begin working on your multi-media or slide show presentation.  Make sure you have a title page.  Include clearly written original recipes (1 recipe per slide) with the recipe conversions.  The last slide should include an explanation of how you converted the measurements and units of measure.  If you actually made a recipe, you might want to include digital photograph of yourself cooking. Your presentation should be well organized and adhere to the rubric. Have fun!

 

Day 6 and Day 7
Presentations will be saved to your portfolio. Students will be assigned to present their final product.
