*This video is part of my free video course for parents, Math That Makes Sense: Elementary Arithmetic. You can find the full list of videos (with outlines and links) here. *

Welcome to Lecture 6! You’ll learn all about how to teach your kids to use the traditional written process to add and subtract multi-digit numbers.

If you’re looking for information on a specific topic, I’ve listed the time stamps for each part of the lecture so you can go right to it.

Happy Math!
