We moved into decimal division today. We will only divide by whole numbers in 5th grade. The process of division does not change. You still divide, multiply, subtract, bring down, check, and repeat (or remainder). The only new idea to a fifth grader is the placement of the decimal. Much like adding and subtracting decimals, you just line them up!
I keep telling my classes that multiplication and division will not go away. Once we get back from our Christmas break, we will be moving into fractions.... including multiplying and dividing them!
