Sharing Brownies
Our class has been studying fractions for the last two weeks and one of our big focuses has been finding fair shares of paper brownies. As a performance assessment recently, students were given a task of cutting a given number of brownies and showing how to equally share them among a given number of people. Some big ideas that we have been learning in this first fraction investigation are:
1) The numerator identifies the number of given parts
2) The denominator tells the number of 
equal-sized parts to make up the "whole"
3) Fractions can be read as ratios (relating the part to the whole) in order to better understand the fraction (ex. the fraction "one-third" can also be read as
"one out of three" equal parts to combine to make one whole
