Finding GCF and LCM with the Upside-down Cake Method - When I first came across the ladder method (ie: the upside-down cake method) for finding greatest common factors and lowest common multiples, I thought it was nothing short of complete genius. In this post, the cake method for finding GCF and LCM is explained. There are also free pdf math word wall references to download for your math classroom.
Greatest Common Factor and Least Common Multiple Anchor Chart. 6th grade Math Anchor Chart! ❤️ Do you use the ladder method to teach GCF/LCM?? Did you know you can use this method to teach distribution and simplifying fractions? I hope this method helps when they learn to factor in high school! I wish I had this method instead of just creating lists. #iteach6th #iteachmath #mathteacher #iteachmath
It's Five for Friday on a Saturday!! :) Time to link up with Kacey from Doodle Bugs Teaching. :) This week we finally got to teaching GCF/LCM within word problems. The students theoretically learned GCF/LCM in 4th grade, but applying it to word problems was a challenge. We started off by reviewing LCM/GCF. I shared with the students how I DISLIKE factor rainbows. In my opinion they are not as easy to use as a table, so that is why I taught them to make a table if the numbers are smaller…
I think factor trees are one of the coolest “tools” for middle school students! Students tend to like them and they have several different uses in middle school math. Here are the 5 ways I use factor trees with my students: 1. Prime Factorization This is the most obvious use of factor trees and it’s typicallyRead more about 5 Ways to Use Factor Trees in Middle School Math[...]
