<p>I just wanted to let the other teachers here know that I have started a blog (doing my part to address the global blog shortage). It's not about SAT math. It's just me writing about math topics and digressions that have come up in my physics class. It's as much about how we present the math as it is about the math itself. </p>
<p>It's at <a href="http://www.advancedmathyoungstudents.com">www.advancedmathyoungstudents.com</a> if you want to take a look. I'd welcome your feedback here or at the blog.</p>

<p>just looked at the blog, great start. i had this old math book from the 1950s that has similar visual proofs for the algebraic identities, but i know that math is rarely taught in this fashion anymore in the US high schools. the rigor has been missing for quite some decades. </p>
<p>a really cool book that i would recommend you to pick up is Proof without Words, perhaps you are already familiar with it.

<p>I just loved the book and again there are many elements in the book that can be adopted for classroom teaching.</p>
<p>a fun exercise would be to have students attempt to create such visual proofs while guiding them through the process. </p>
<p>cheers.</p>
<p>I’ve seen that book and looked over a few of the proofs. It is very elegant. And I do think it would be a good use of class time – better than the time spent constructing those “statement-reason” proofs.
Thanks for checking out the blog. I am going to continue the theme of diagrams and equations for a while longer. </p>
<p>I love it. In fact I’m going to share it with my social media followers.</p>
<p>Thank you, DrSteve. I hope I can keep it going.</p>
