Least Common Denominator

In this free math video, you’ll watch my 6 and 8-year-old make the connection on their own that when you add fractions with different denominators, you need to find the least/lowest common multiple of the denominators. It is so amazing to me to see them figuring these things out on their own. I remember being confused about this stuff in school because it was just a bunch of rules to memorize without explanation of WHY. My kids understand the WHY and so they are able to come up with the rules on their own. AMAZING!
