Introducing the Mathtwitterblogosphere
#MTBOS stands for the Math Twitter Blogosphere. It is the source of much mathematical goodness.
This page was set up as a resource for teachers who attended my workshop on Improving discussion in maths and stats classes.
Here are some of my favourite sites, and links talked about in the workshop:
Becoming the math teacher you wish you'd had
Tracy Zager has written a wonderful book, called "Becoming the Math Teacher you wish you'd had." We find this book both inspirational and practical. The site has great links also.
Which one doesn't belong (wodb)
Which One Doesn't Belonghas its roots (I think) as a shape book, but has many wide-ranging applications. Basically there are always multiple answers, which makes discussion richer.
Notice and Wonder
This is a pdf of an explanation of Notice and Wonder,and a challenging problem.
This one took me a while to find - no one seems to acknowledge its origins. I think this chapterfrom "Using Math talk to help students learn" is the source of the list of five talk moves. There are many many illustrations of these, easily found by Google image search.
I think 100 questions is a bit excessive, but it does have some good ideas.
Fawn was one of the first #MTBoS ers that I found out about. I love reading her writing, as it is subversive, yet kind. Her blog is called Finding Ways and has an eclectic mix of practical ideas, philosophy and heart. There is a great set of links. Fawn also curates Visual Patterns, which is a wonderful selection of... visual patterns!
In New Zealand, Bobbie and Jodie Hunter have been encouraging Maths Discussions. This little videogives a summary.
