Welcome to #104 of the Math Teachers At Play (MTaP) blog carnival. A blog carnival is a regular blogging round up coordinated by someone (in this case Denise Gaskins) that moves around different blogs each edition. This time, I’m taking a turn.

### Mathematical app roundup, October 2015

I notice that our post queue is filling up with interesting mathematical apps, so I thought I’d deal with them all in one big roundup post. Read on for a mix of mathematical games, apps to help with calculations, and some frankly awful art.

### 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:

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.

### Each pair of smartphones has exactly one Dobble app in common

Card game fans might be familiar with the game of Dobble, in which a set of cards featuring symbols is laid out on the table, and family members tear each other’s hands off/eyes out in order to find the one symbol a given pair of cards has in common. Well, it’s now also available virtually!

### Manchester MathsJam recap, January 2015

Manchester’s first MathsJam of 2015 (and indeed, all the other first MathsJams of 2015 in cities all over the world) met on 20th January, rousing us all from a Christmas-induced slumber and gently easing us back into a year of recreational maths. Here’s a round-up of what we did.

### Just Get 10

Here’s a new numberiffic game from Veewo, the people who made noted Threes-a-like 1024 (which begat 2048, which inevitably begat 2048: Harry Styles edition).

In *Just Get 10*, you have to ~~get at least nineteen~~ combine numbered blocks until you get one with a 10 on it. If you tap two adjacent blocks with the same number, they’re replaced by a single block with the next number up.

It’s alright.
