New YouTube videos by me and James Grime

I’ve been at it again, making videos for that YouTube – this time, a collabo with James Grime. We have each posted a video on the topic of a mathematical game, as we both had things we wanted to make videos about but nobody to play with, so we met up after school and made some YouTubes.

My video features two games which *SPOILER* turn out to have maths in them. I’m also doing a bit of a giveaway on Twitter, where you can win the actual cards used in the video (I will post them out in the IRL post mail), so reply to this tweet if you want a chance to win:

James has also posted his video, which is about a different game:

Review: Factris

Removing four lines at once with an I-piece in Tetris is the most efficient way to score, which creates a tension: on one hand, you want to build high enough to score quickly, but on the other, building too high puts you at risk of ending the game. The balance between the two is exquisite.

I mention that, because I was about to grumble that the corresponding balance in MEI Maths’s new game app thingummy Factris isn’t quite as good – of course it isn’t. Nothing ever will be.

Take the 30 second arithmetic challenge

My wife’s grandmother is a fearsome character. She’s in her nineties but still has all her wits about her. In fact, she’s got more than her fair share of wits. Whenever we visit her, she hits me with a barrage of questions and puzzles collected from the last several decades of TV quiz shows and newspaper games pages. My worth as a grandson-in-law is directly proportional to how many answers I get right.

One of her favourite modes of attack is the “30 Second Challenge” from the Daily Mail. It looks like this:

quiz0512_800x310

You start with the number on the left, then follow the instructions reading right until you get to the answer at the end. It’s one of Grandma’s favourites because it’s very hard to do in your head when she’s just reading it out!

I decided it would be a fun Sunday morning mental excursion to make a random 30 second challenge generator

Programming to investigate Quarto

I was invited to contribute to a special issue of The Mathematics Enthusiast on ‘Risk – Mathematical or Otherwise‘, guest edited by Egan J Chernoff. I wrote about the Maths Arcade and programming strategies for a game we play there called Quarto. Really, I was sketching an outline of an idea to encourage student project work.

My title is ‘Developing Strategic and Mathematical Thinking via Game Play: Programming to Investigate a Risky Strategy for Quarto‘ and the abstract is below.
