1.)Introduce the lesson by asking students to describe their favorite meal. Ask students what they would need to do if they were preparing that meal for the entire school. Explain that it is important to be able to add, subtract, multiply, and divide fractions in real life.
2.)Tell students that they are going to have the opportunity to search for a recipe on the Internet. Instruct them to find a recipe that sounds good, because they may have the opportunity to create the recipe in class.
3.)Requirements and Student Instructions:
a) Choose a recipe with at least five (5) ingredients. Write the recipe down on the provided sheet.
b) Double the recipe. Show work. Use sheet provided.
c) Half (1/2) the recipe. Show work. Use sheet provided.
d) Explain in complete sentences how to adjust the recipe to feed 20 people. If quantity served is not given, estimate how many it will serve and explain what would have to be done to feed 20 people. Use sheet provided.
e) Present the information on a poster board in an interesting way. For example, use pictures of a stove, refrigerator, potholder, or something to do with the item being prepared.
