Nifty Tricks for the Number 6!
The other day I came across this and never realized that 6 multiplication facts repeated in this way or had this pattern! Imagine, I have been looking for patterns in the 6’s for years and never realized this. Did you?!
I mean I knew you could double your 3’s facts to find your 6 facts, but I never realized this happened with the even numbers. I am sure you can tell by the image above that the factor multiplied by 6 repeats in the ones place of the product! Hmmm, I wonder if this happens with more digits? Well, does it? 🙂 What a great problem to pose to your students. Then ask them to show other examples of this working or not working with larger numbers. I wonder about odd numbers….does this idea work with odd numbers? Hmmmm? What fun!!! Do you know any more tricks that work with 6?
