Yesterday I happened upon a TikTok video that demonstrates a very cool method for solving multiplication problems.

I couldn’t wait to share it with the kids. They were fascinated and turned the front porch into a giant chalkboard for practice sessions.
In this video, Miss Chang shows how carrying works:

This Youtube video walks through a few more problems, including some with three-digit numbers and carrying over. The method works with larger numbers but gets a bit unwieldy beyond three or four digits.
So cool!

So cool! Evelyn is running out to get the sidewalk chalk now! Combine this with Bubble Gum math, and you could take this show on the road!
