This is a video made by another teacher, Christine Munafo, explaining the process and steps of long division. We have watched this in the classroom, but this will provide an excellent review for your child.
We also watched a video “Long Division Style”, which is a parody of the song “Gangnam Style”. Although the video talks about dividing decimals (which we don’t do in the 4th grade), the process of division is still basically the same. It’s just another fun tool to the kids can use to help them with the steps of long division! 🙂
