Have you ever wondered if there is a better way to understand and remember mathematical order of operations than PEMDAS, BIDMAS, GEMA, or any of the other happy mnemonics that only go so far? It’s been a bugaboo for so many teachers over time. During a recent work trip to St. Croix, USVI, I realized I hadn’t written my thoughts about it in my book. So I wrote a chapter all about it. If you’d like to read the chapter, wonderful! Just sign up to my email list, and you’ll get a link to download it for free. Don’t forget…

I’m so inspired about a new tool to enhance math education. A friend sent me the link to a TED talk (embedded at the bottom of this post) showing the evolution of the Khan Academy into something truly useful for – well, for just about anybody. I had come across the Khan videos some time ago, and I thought they were useful and well designed to teach more advanced concepts.

What is their misconception? Add a comment with your thoughts!
