The 5-4-3-2-1 Challenge from Will Shortz and NPR. On Sunday morning, Nancy Swank tweeted me a link to a puzzle on NPR's website.

This shouldn't come as a surprise because Nancy is the entire reason why NPR spent an entire day in my classroom in 2014. I followed the link and started reading the puzzle. The Higher Lower Game. Estimation 180 - Home. Open Middle - Challenging math problems worth solving. 1001 Math Problems.

Wodb. 'Taught right, every maths pupil could be a Countdown winner' In 1997, James Martin, a quietly unassuming Oxford maths PhD, entered television gameshow folklore with his stunning solution to a maths problem on Countdown.

The challenge: make 952 using the numbers 100, 75, 50, 25, 3 and 6. You may use the four standard operations of addition, subtraction, multiplication and division. You do not have to use all the numbers and you cannot use the same number more than once. Oh, and you have 30 seconds. James' solution has made it on to YouTube – well worth four minutes of your time: The clip is television gold. We’re all thinking the same thing. Most people can get to 954 easily enough: 106 x 3 = 318 318 x 3 = 954 The brilliance of James’s solution is in how he negotiates the excess of 2: 100 + 6 = 106 106 x 3 = 318 318 x 75 = 23,850 (this is where Carol loses the plot – numbers this high are very rarely seen on the show) 23,850 - 50 = 23,800 (Carol is completely hysterical by now) 23,800 / 25 = 952 Looks pretty remarkable, right?

I have been using Number of the Day (see separate blog here) for some time and found it to be a useful way of regular revisiting a range of basic number skills.

I began wondering whether it would be possible to use a similar resource to practise basic algebra skills. The result is Expression of the Day. I haven't had the chance to use this very much yet so it may well get adapted in the coming weeks and months. However, the picture below gives an indication of the kind of questions I might pose to students.

As with Number of the Day, the possibilities for differentiation here are almost limitless. MathsMuggle: Starter activity - Number of the Day. I should start this post by explaining that this isn't my idea and I'm afraid that I have no clue where the original idea came from.

If you know, I'd be interested to hear from you. My version of Number of the Day has been adapted from something that a colleague showed me about 5 years ago. I find this to be a very effective starter activity for a Maths lesson. Students are expected to complete a range of different questions using a particular number as their starting point.

The questions cover aspects which would probably be considered as 'basic' number skills - the sorts of things that I want my students to be really confident about. The teacher can choose to include all of the questions or just some by ticking the small boxes. Hello and welcome to my 31st gems post.

This is where I share some of the best teaching ideas I've seen on Twitter. 1. Ratio tables The new GCSE is going to have an increased focus on proportional reasoning. Hello and welcome to my 29th Maths Gems.

This is where I share five teaching ideas and resources I've seen on Twitter. 1. Nix the Tricks Videos I've long been a fan of the book Nix the Tricks - I think it should be compulsory reading for all trainee maths teachers. I'm excited to see that Owen Tabbert (@OTmath) is making a series of Nix the Tricks videos for teachers. I think these videos are going to be incredibly useful - not only for non-specialists and anyone preparing to teach maths for the first time, but also for experienced teachers reflecting on how they explain mathematical concepts. Back in Gems 18 I featured five ideas from the first 100 issues of Chris Smith's newsletters.

Secondarymaths - algebra countdown.xls - Detail. Starter Activities - Interactive Maths - The Interactive Way to Teach Mathematics. Most of my readers probably already subscribe to Chris Smith's lovely maths newsletter. Full of teaching ideas, puzzles, jokes and mathematical trivia, it's a joy to receive every week. Chris has been producing the newsletter since 2007 when he was a wee NQT. Amongst other things, the newsletter is a fantastic mechanism for sharing good practice. I enjoyed meeting many of you at La Salle Education's National Mathematics Teacher Conference yesterday. It was a fantastic opportunity for sharing ideas. But 500 maths teachers out of 350,000 is a drop in the ocean. It's such a shame that so many schools weren't represented.

Although there are some pockets of collaboration throughout the UK, for example through regional TeachMeets, the fact is that the majority of UK maths teachers live in a bubble. 30-maths-starters.pdf.
