Description:
This 15-minute Common Core Math video explains how to add and subtract fractions by first having the same units (denominators). It first gives an example of cats and dogs being different units, thus making them incapable of being added together. It then goes on to use visual models to represent addition and subtraction of unlike fractions. This video can be used independent of the Common Core Math curriculum, but is best when supplemented with the curriculum.
Purpose:
To learn how to model addition and subtraction of unlike fractions.
