5 Maths Stone #74

Welcome into my 74th stone post. That is where I discuss a number of the most recent news, suggestions and tools for maths teachers.

1. Area Mazes
Two years ago I wrote about Space Mazes at  Stone 36 . Last week Nicke (@NEdge9)  advised me about the lovely website areamaze.com  which I’d never noticed before. This simple, user-friendly website presents a set of increasingly tough area mazes for students to work through online. Helpfully, students can draw focus about the diagrams whenever they reason their way through the mysteries.

2. Animations
Tim Brzezinski (@dynamic_math) has been tweeting some brilliant online geogebra things recently. I like to use things in this way in courses as a piece of my own explanations. No Geogebra skills are required! For example Tim has created excellent   collections of cartoons for outside angles  along with  interior angles of polygons  plus a instrument exploring linear expansion vs exponential expansion. Follow Tim on Twitter for a lot more like this.
Another smart animation that I seen on Twitter this week has been just one by Kendra Lockman (@klockmath). Kendra has made a instrument in Desmos: ‘ ‘Adding Integers on a Number Line’ which is well worth a look.

3. Angles in Polygons
Ed Southall (@solvemymaths) has been discovering about maths education over in Japan and will undoubtedly discuss a lot of blog posts and posts about what he’s uncovered. He’s tweeted about several approaches for locating a formula for the interior angles of polygons.

Most educators go with the first approach here, but for some time I have believed that the second approach (triangles that match in the centre, resulting in the formulation 180n – 360) might be more intuitive. It’s worth talking about.

MathsPad has released a brand new pair of Odd One Out sources. Students   need to find matching pairs from nine items in a box, and then circle the odd person out. These actions are designed to draw out possible misconceptions. There are currently nine topics available to MathsPad readers and two topics out there for free: Reciprocals and Simplifying Surds.

5. End of Term Quiz

My post ‘End of term funds’ lists maths actions that are useful when you have a half a class or half of a lesson. I believe it’s extremely important to keep teaching maths up into the last day long – that I never give in to students’ requests for films or games! But sometimes lessons are disrupted by college occasions, meaning teaching a new subject becomes difficult. This presents a good opportunity for maths enrichment.

Thanks to Richard Tock (@TickTockMaths) for sharing his own End of Year Quiz. This quiz is extremely mathsy and is written specifically for summertime 2017.
Update
I’m very pleased that test season is over! It’s fantastic to have some gained time, though I’m really busy composing UCAS testimonials, sorting out displays before available day, and locating resources for the new A degree. I’ll be blogging about brand new A level topics shortly.

I had been appointed to the role of Acting Joint Head of Maths at Glyn School (it’s just maternity cover, and that was the sole applicant, but hey – it’s great to receive a temporary marketing). It’s definitely going to be a challenge but I’m delighted to be given an opportunity.

I’m presenting my Angles in Depth workshop at the ATM & MA London Branch  seminar this Saturday so if you’re located in London, do come together.

Don’t forget to book tickets for my #summaths occasion!

I’ll give you this lovely activity ‘Ab-surd! ‘ from afar – I love surds!
