Скачать или смотреть How to Simplify fractions using visual models and primes

Using prime numbers to simplify fractions is an easy way for all students to develop this skill. Even if students don't know their division facts, they'll know how to simplify fractions with this method. Students can work through a list of prime numbers with a calculator, testing if both the numerator and denominator divide by each prime. After posting the left video on social media, I was asked why this method works. My hope is that the video on the right, right showing fraction simplification with visual models, answers this question. You can grab the dot sheet seen in the video along with a free simplifying fractions flowchart through this post on my blog: https://www.scaffoldedmath.com/2021/1...
