*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 1! You’ll learn all about how young children develop number sense, how our base-ten number system makes life easier, and how to teach your children place-value.

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!
