## Common Sense and the Common Core "Supporting Computations in Division"

Assistant math professor, Darrell Blanks, will demonstrate two concepts of division developed in 3rd grade which will later be used in math that is found in subsequent grades. Students who can see both of these concepts of division, making equal groups or taking out equal groups have a foundation upon which they can understand procedures associated with division and therefore have the basis upon which they can determine reasonableness of their answer. The lesson will demonstrate that this same approach may be used in a 6th grade division problem for fractions.
