5 Maths Gems #67

Welcome to my 67th gems post. This is where I share the latest ideas and resources I've seen on Twitter. I used to write one of these posts every week but I now struggle to find the time, so this is my first gems post since November. I have some crackers for you today though!

1. Polygons
Ed Southall's (@solvemymaths) first video is well worth a watch. It explores the terminology, etymology and structure of naming polygons. I'm now eagerly looking ahead to when I next teach geometry so I can share this with my students!

2. My Favourite No
I first watched this video years ago but I've never put it in a gems post before. Thanks to Stephen Godwin (@stevejodwin) for reminding me about it after it appeared in Doug Lemov's recent blog post 'My Favorite No: Mistaking Knowledge Problems for Skill Problems'. Do watch the video below - it features a brilliant activity for exploring misconceptions.

3.  Primitives
I shared the lovely Furbles in Gems 21, but hadn't spotted the 'Primitives application' on the same website. This has been around for many years, but thanks to John G (@mathhombre) for recently sharing it on Twitter. This lovely interactive factorisation tool is really good for exploring numbers.
Primitives posters and teaching ideas are available from the ATM.

4. Euler's Number
Numberphile published a new video about e last week. I really enjoyed this video and plan to show it to my Year 13s next term.

5. Notepad Calculator
Colin Beveridge (@icecolbeveridge) tweeted about this excellent NotePad Calculator. I'm not sure whether I'll find it useful in the classroom but I love it anyway so thought it was worth sharing.

I've published six blog posts since Gems 66. They're listed here in case you missed them:

Do check out Don Steward's blog too - he's published a lot of new resources lately.

I'll leave you with this animation of the surface area of a sphere, shared by Damian Ainscough (@damianainscough).
