*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 3! You’ll learn all about how to teach your kids to understand the concept of subtraction and master the subtraction facts. Plus, you’ll learn about the purpose (and common misconceptions) of mental math.

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!
