In this blog post, Kathy Liu Sun, assistant professor of education and former high-school math teacher, shares tips for choosing technology to support math instruction. I found the post through the Math Education SmartBrief distribution mailing I receive daily, firstname.lastname@example.org. If you’re interested in what is happening around the nation in math education, I highly recommend subscribing to this list. Each day, you receive links to, and a short description of, articles/posts in the areas of math teaching and learning, curriculum, STEM, and policy and legislation. It only takes a moment to scan the titles for something that peaks your interest.
