Math is an important part of our everyday lives. By acquiring the necessary skills dealing with fractions, we can simplify our lives. The purpose of this project is to help you understand fractions. We are going to have fun with fractions. We are going to have a party and invite all the 7th grade students, teachers, and principals to our party. What is this party for you ask? To show off our fraction skills by cooking pizza and brownies and by making some delicious punch.

This webquest will allow your group to choose a recipe, either a brownie, pizza, or punch, depending on which item your group is assigned. Then your group will decide the amount that is needed for the number of 7th grade students, teachers, and principals.

Step four : Again, hit the back icon at the top of the screen, scroll down and choose "Multiplying Fractions". This one is easy but make sure you show me how to multiply fractions before going on to step five.

Step five : Hit the back icon at the top of the screen, scroll down and choose, Multiplying Fractions with Whole and Mixed Numbers". Prove to me that you can multiply fractions with whole and mixed numbers and you are on your way to the last step.

Step three: Study the recipe ingredients to determine how the measurements are to be changed to produce the specific amount needed.

Step four: Change the measurements using excel spreadsheet. See microsoft tutorial below. Be sure to create formulas so the measurements are converted and correct. Turn in the orginal recipe and the Excel Worksheet showing the modified recipe. This is the same assignment that you will find below.
