GoMath Chapter 7

Our class will be learning how to add and subtract fractions and mixed numbers over the next few weeks.  First, we will use models to find the sums or the differences.  Then we will record equations to match our models.  Finally, we will add and subtract without using models.  Our homework will be practice adding and subtracting fractions with and without models.  There are ten sections in this chapter.
