<p>When you see 15-7, do you know that 15-7 is 8 or do you really think in your brain that 7 + 8 would make the 15?  Are you using your addition facts to help you with the subtraction facts?  A lot of people do, but a lot of people also see them as isolated facts.  Sue O’Connell and John SanGiovanni (and many other researchers) have noticed that when kids have addition fluency and they have built the connection between addition and subtraction, they are more fluent with subtraction.  I’m sharing a snippet from their book Mastering The Basic Math Facts in Addition and Subtraction.  Get a link to the book and other resources mentioned in this episode at buildmathminds.com/87 </p>

Episode 87 - The Power of Addition in Building Fluency in Subtraction

The Build Math Minds podcast is for my fellow Recovering Traditionalists out there. If you don’t know whether or not you are a Recovering Traditionalist, here’s how I define us. We are math educators who used to teach math the traditional way. Flip lesson by lesson in the textbook, directly teaching step-by-step how to solve math problems. But now, we are working to change that to a style of teaching math that is fun and meets our students where they are at, not just teaching what comes next in the textbook. We want to encourage our students to be thinkers, problem solvers, and lovers of mathematics..we are wanting to build our students math minds and not just create calculators. If that is you, then this podcast is for you.
