Adjusting a Recipe Project

midlit11_img_splfractrecipe

 

Find a simple recipe in a recipe book or on the internet with at least four fractions in the ingredients list. Include the original recipe within your project.

 

Be sure to show your calculations, explain your strategy and include visual models.

 

Within your project you must:

 

-Rewrite the recipe for twice as many people. (adding, doubling, multiplying)

 

-Rewrite the recipe for half as many people. (subtracting, halving)

 

-Explain how you would adjust your recipe to feed everyone in your class

-If the quantity served is not given, estimate how many it will serve and explain what you would do to have enough for us all.

 

-Present your information in a CREATIVE way.

 

-Make the recipe for 4-6 people and bring your project to our Fraction Feast on International Day! (March 31st)

 

– Remember to use the rubric as a guide!
