2. Can you extend it?
3. Can you generalize it?
4. Can you prove it?
5. Did you learn anything new?#thinkingclassroom #flow pic.twitter.com/2OklCMYbOl

Someone put the Unusual Baker problem (NCTM, BTC) on Mathigon. Thank you! (I wish I could give you credit.) Cake #7 doesn't look the exactly the same as in @pgliljedahl's book (Figure 10.1), but I like that it is going to the midpoints. https://t.co/xF1qJ5r3Z9

My favourite thing about this video is that with a typical solution you might hear a phrase like "cross multiply" but here @Howie_Hua uses one of my favourite properties - so good.

I have been a fan of the Mathies.ca math apps for years and was disappointed when they went away when Flash went away. But some money has been found and some of them have been recreated in HTML5 so that they will live on. Currently, the Money app and the Colour Tiles app have been released with others on the way (some of the other minor apps are also in HTML5).
