I've been making CII (Correct, Incorrect, Incomplete) tasks to deepen students' understanding of particular topics. First, they discuss the Correct work in groups and I ask them questions. They do the Incorrect column and we debrief, then they finish the Incomplete. #MTBoS #iteachmath bit.ly/3YXGpW2

I am printing a noperthedron pencil holder :) #mtbos #mathart #noperthedron

A teal noperthedron with a cylindrical hole in a drafting program with shadowing. The shape is vase-like with triangulated faces, but bulbous at the center and slanted inward at the top in bottom so that there is a band of 3 layers of shorter triangles in the middle and longer more angled-in triangles at the top and base of the vase (container).

♾️ #ITeachMath Please remember that no one makes the content here but us. Community will not be created without things to think and talk about. I may be verging on annoying but I care very much that math educators have a space to converse and grow! #MTBOS

During the last week of school, I had some students ask me if I had any coloring pages they could have. I didn't, but I did add "make mathematical coloring pages" to my to do list for this summer! mathequalslove.net/geomet…. #mtbos #iteachmath #mathsky #edusky

The #math community seems to be growing here and becoming more active. I have presented on how to get the most of being in a community like this many times and here are my tips to grow this PLN and make it useful for educators. Bonus Tip - Use the Feeds: #MathChat #MTBoS #iTeachMath #MathSky

Tips to move beyond a “lurker”
(and/or start to interact with the Online Math Community)
Like - Who benefits: You (it acts like a bookmark) & the Poster (“Yay someone liked what I said”)
Repost - Who benefits: You (it acts like a bookmark), the Poster (“Wow, they liked enough to share it”) & the rest of us (Reposting sends it back to the top of the feed increasing the chance of your followers and their followers to see it)
Comment - Who benefits: You (interaction brings more friends and knowledge), the Poster (the conversation they started continues) & us (entices us to become part of the conversation too)
Post - Who benefits: You (sharing thoughts and resources help to hone your own ideas) & Everyone else (the more discussion, the higher the chance we all learn)
Tips for making your Posts more visible:
Add an image - including a visual has been shown to increase the interaction
Include hashtags (not too many) - a hashtag categorizes your Post and makes it visible to a wider audience than just your followers. Here are some math related hashtags that relate to education: #MathChat #MathsChat #MTBoS #iTeachMath #ElemMathChat #MathArt #MathSky
Tag some people (not too many) - you can tag relevant people (even those who don’t follow you) in the Post or in the Image to increase the conversation potential

Math friends! I've finished (for now) getting my lectures on logic for proofwriting into booklet form: crgibbons.github.io/Logic…. If you love it but also hate it, you can fork it and improve it! github.com/crgibbons/Lo... Please share with folks who might find this useful. #MTBoS
