This Saturday I wanted to do a little trip around the blogosphere to look for things to blog about. As much as this blog is about documenting my growth as a teacher, this blog should provide a space to document what I am learning from other people. This week I felt like learned a lot from a number of things I read, but when it was time to get a post up, these are the ones that stuck out in my head:
@trianglemancsd has been going through the questions from the ‘Grant Wiggins Challenge’, and has produced a set of great posts that quickly challenge the depth with whcih I thought about the mentioned topics. I was really interested in the third question, where Wiggins’ asked about the often-memorized, rarely-conceptualized, ‘same-change-flip’ algorithm for division of fractions. Danielson’s response introduced the words partitive and quotative division into my vocabulary and led me on a fascinating trip down a mathematical rabbit hole which could rival a graduate class.
Also interesting is that Grant Wiggins himself shows up in the posts, creating a pretty interesting and cordial conversation (their interactions stop far short of a Public Intellectual Death Math).
@mythagon created the cutest video about (not) grading math assignments and there is really know way you can’t watch it. It was based off of an article that I had read before and forgot when the school year started, that I was happy to rediscover. I was disappointed that I was in the middle of grading when I watched it, as it made me instantly want to change my practice.
