Division - 4th grade math

This is a beginner lesson where we look at visual models to understand what is REMAINDER in division. The first examples have to do with sharing division, and the latter ones with "measurement" division (where you know the size of the groups). Either way, the remainder is the "leftovers" -- the items that cannot be evenly divided into groups. I also emphasize how we can check a division problem with a remainder by MULTIPLYING -- and then adding in the remainder. All of this is done with mental multiplication and mental math - no long division. Check out also the NEXT lesson where we practice finding remainders in division: This lesson is meant for 3rd or 4th grade math.
