It's no secret that I'm a fan of Desmos and they have been putting out new features steadily. This latest one is the ability to include ordered lists as part of activities now. Whether you create your own activities or use theirs, it's another nice feature to help discover your students' thinking. Check out some of their activities that have that feature already at the link below.Curriculum Tags: All

Based on @pgliljedahl's blog post for @edutopia on Building a Thinking Classroom in Math, I've made a checklist/self-assessment for teachers looking to implement these ideas. Feel free to use!— Heather Theijsmeijer (@HTheijsmeijer) April 28, 2019

Some great discussion in the comments from the Tweet plus good resources in the link on this one but a surprising result. Who knew that such a little rotation would cause it to intersect the axis.

Suppose we tilt the graph of y=x^2 (well, rotate it, actually) counterclockwise about the origin just 0.01 degrees. Does the y-axis intercept this tilted graph at some large non-zero value? (From https://t.co/5uTZ0uhUrs) pic.twitter.com/oBFXDl5312— James Tanton (@jamestanton) April 27, 2019
It's always good to have questions to ask students to keep them thinking while you are working with them.

I totally get the idea of looking back on my career and thinking that my methods were archaic. In this article @MrBartonMaths talks about his experience which is the context of his new book.Curriculum Tags: All

I just binge listed to this new (to me podcast) Math Before Breakfast. The premiss of @mathb4breakfast is that two elementary teachers (@math6teacher and @tracyjoproffitt) go for runs together a few mornings a week and talk about their math teaching practice. So they started to record their conversations (thankfully, not while they are actually running). I wasn't sure what to expect when I started to listen but I really love the way that they talk through pedagogical ideas in order to plan out what they are doing in their classes. They share a lot of resources (like tonnes of links per episode) and even if you may have heard of some (or all) of those resources, that peak into their teaching and planning process is really useful. Check it out and all of the other new podcast episodes listed on my podcast page.Curriculum Tags: Gr7, Gr8
