Previously Published Data 

1.) Working in pairs, students will build fraction problems with manipulatives, find common denominators, and solve simple addition fraction problems with and without mixed numbers. 

2.) Working in pairs, students will build fraction problems with manipulatives, find common denominators, and solve simple subtraction fraction problems with and without mixed numbers. 
3.) Working alone, students will build fraction problems with manipulatives, find common denominators, and solve simple subtraction fraction problems with and without mixed numbers. 
4.) Students will add and subtract fractions and mixed numbers without the benefit of manipulatives. 
Previously Published Data 

1.) Students will explain the process of finding common denominators and demonstrate how it is done with and without manipulatives.
