4th Grade ~ Long Division

This week the fourth grade students have been learning how to do long division. This is a difficult concept for many students to learn so your students will be taught several different methods that division can be done and they can choose the method that they understand. If your child understands more than one way and chooses to use a different method for different problems then that is OK. The method they are learning this week is called, "partial quotient."

When we divide we can use our base 10 system to help us determine out quotient. While multiplying by 1, 10, 100 and 1,000 we can easily find large chunks to subtract from the dividend to find the total quotient.

An example is listed below of how the students would divide 384 by 3 using partial quotient.



Using partial quotient your child can determine that 384 divided by 3 equals 128.
