The Carnival of Mathematics is a fortnightly round-up of maths blogging, which has just reached its 50th incarnation. It’s a travelling show, and is currently docked at The Endeavour. Have a look, there’s some great stuff there (and a bit by me).
I will try to link to updates even when I’m not featured. But you can always find details here.
There’s also a brand new maths teachers at play carnival, focused more on school level mathematics and teaching ideas.
