Adding fractions for pizza: planning

The students have been learning about fractions in math the past few weeks, and lately have been working on adding and subtracting fractions. I had told the students last week that they would need to use their fraction addition/subtraction skills to achieve a classroom goal, but I didn't tell them what it was. The following day, I told them that they were going to have to use those skills to help plan a pizza party - needless to say, the room crackled with excitement! They broke off into groups of 4 and 5, and then figured out how many fractions of pizza they wanted, and the variety of pizza as well.

Today, we took the next step, and as a class, we added up all of those fractions to figure out what exactly we need to order. It took some work, and a couple of people (thanks to those volunteers!) had to shift their choices around a little bit, in order for us to get our final totals as close to whole pizzas as we could, but we did it! What a fun way to have the class working with adding and subtracting fractions, converting fractions to whole numbers, and rounding - it'll be even more fun when we order the pizza, and eat the 'fruits of their labour'!
