336. Geometry Snacks

If you are looking for a very last minute gift for that special Mathematician in your life, or you have Christmas money to spend, may I recommend “Geometry Snacks” by Ed Southall (@solvemymaths) and Vincent Pantaloni (@panlepan)?

It is a nearly pocket sized book of geometry puzzles whose construct of simple, elegant problems can decieve the unwary into thinking the solutions are easy. This is a book for those who embrace mathematical rigour, rather than repetitious guesswork.

In fact, forget buying it for someone else – get one just for yourself!

Geometry Snacks is published by Tarquin (ISBN: 9 781911 093701)

333. Resource of the week

Just a quick resource for you today and apologies if you are already using this!

Plickers

Not some new ‘youth slang’, but an amazing online tool. Students have an individual card with each side labelled A, B, C or D. You ask a multiple choice or True/False question, they hold up their card with their answer at the top, you scan the class set of cards.

It really is that simple and here is what to do to get started:

  1. Create a free account at www.plickers.com
  2. Download the app to a portable device with a camera (phone, tablet etc)
  3. Print out the cards
  4. Allocate the cards to your class on the website
  5. Stick the cards in your students’ books
  6. Set a question
  7. Scan the cards

I have a tablet device that I use for school purposes as I keep my phone for personal use. The only problem I had was my android tablet doesn’t have a light source or as high quality camera as my phone, but we sorted that by having students move to a brighter part of the room for scanning. Instant feedback with no handheld devices!

Finally I have to say a huge thank you to Mr L, our trainee teacher, for introducing this to the Department.

332. Movement Maths

I’ve got to share a new YouTube channel with you. It was created by a former colleague who is not only an ace Maths teacher, but also a trained children’s fitness instructor. ‘Movement Maths: How to survive High School Maths’ is all about daily chunks of Maths with a fitness boost.

First – it addresses basic concepts that many students forget or stress over (initially it will be aimed at Foundation students)

Secondly – the videos are engaging and show that you can do Maths and exercise anywhere (my current favourite is the airport in video 13 – how did he find an empty sp?)

Thirdly – there are recaps and summaries built in

Finally – it was reviewed by students, who loved it!

Update: 1st June 2019

It appears all the videos on this channel have been deleted.

331. Personalised student/parent feedback

How did I do in the test?

We get that question all the time. Is that a good result? Is it bad? Where did I come in the class? In general I never answer any of those questions, instead I have a little one to one chat as I’m handing out papers or in subsequent lessons.

But what if you’re not there to have that interaction?

I had that problem this summer. We were due to give our end of year test results back to students on the same day I was on a school trip. I couldn’t give the results out early and I didn’t want to make my class wait. If they were just given their test results or papers back, that would be a feedback opportunity missed. What to do?

I ‘wrote’ a letter to each student.

I use the word ‘wrote’ in the loosest sense. I mail merged their results and targets into Word, using my markbook spreadsheet as the data source. That addressed the facts element. The bigger picture for the class was the interesting part. If you search for ‘DESMOS’ box plot, you will find a sample box plot. If you replace the data with your test results, you will obtain a box plot of your results. I put my box plot into the master document and hit merge:

Each student recieved a personalised letter, in an envelope, in my absence. I could even give results to the students who were on the trip with me.

The letters were a big hit with my class. They liked that I had gone the extra mile for them, even though it took under 20 minutes. In the subsequent lesson we could get on with the test review without lots of questions about numbers and grades.

It got me thinking – could I use this idea in other ways?

I have refined the format (the initial letters served their purpose, but we’re basic) and have since used variations on this for other assessments and at Parents Evening. Parents Evening was particularly useful as I had all the target and assessment data, key exam dates, class summary box plots for the last two tests, suggested GCSE revision resources and a reminder of what the new GCSE grades mean. I didn’t have to keep refering to my mark book as all the relevant information was in front of me and the parents didn’t feel the need to make notes. I had very few questions about set changes as they instantly got a feel for where their child was within the class, but without any rankings. Several said that they wished all subjects would produce information sheets like this.

I could also give the personalised sheets to students whose parents couldn’t attend or email them home. It was a very useful tool for getting identical information to those families who are apart, but are equally supportive of their children. When the Head of Year asked for a brief summary of a student’s progress, as they were meeting with a parent on Parents Evening, it was already done.

Of course, the great thing is that I will only have to do a minor update for the next Parents Evening saving me even more time!

The next time you have to give out and/or discuss data with students or parents, try this. It really improve the experience.

330. Still Dancing Men

You may already know about my blog posts on the ‘Dancing Man’ cipher. If not, check them out here;

34. The Dancing Cipher

97. The Dancing Cipher (part two)

Now, I have two parallel classes and I want to set the Dancing Man project as a homework, but they’ll be doing the task at different, but overlapping times. I don’t want the second class to have an unfair advantage, so I’ve written a second task. All the instructions are the same, but it’s a different text. I’m not sure whether to give each class a different text or whether to randomly assign both texts within both classes to avoid copying/generate confusion.

This text is a little more interesting than the last one … think zombies!

You can download an advanced (Beta?) copy below and I’ll update you on how it went, after I’ve done it.

326. Instant whiteboard

Welcome back to school!

I must say your display boards look lovely …

What’s that? You could do with another whiteboard

Why would you need that? They’re not cheap you know!

To help you actually teach? You’ve never needed the space before…

Oh … you have needed the space … you have raised this before …you’re still waiting …

Why didn’t you say! I’ll put you on the list for when we have some spare funds & time

You know the feeling – you could do with more space, but there just aren’t the funds to do anything about it. I initially needed an extra notice board because two form groups were going to use my room. We have a split lunch and I thought it only fair to give the other tutor some space. The idea of those ‘magic whiteboards’ was nice, but they are flimsy and expensive. They’re also pretty useless when you have a rough breeze block wall. Rummaging around Amazon I found some extra thick sticky back whiteboard roll, which was half the price of the ‘magic’ ones. There are a lot of different makes and sizes of roll depending on your needs. I bought a long narrow roll and cut it in half: it fits splendidly on my double doors. The quality is good too, however I think they’ll need a bit more TLC than a heavy duty whiteboard.

So, I’m feeling rather chuffed by my ingenuity when I discover they’ve changed our form rooming and I’m no longer sharing with another form. Nevermind – one board for form notices and one board for homework reminders!

If you like the look of mine it was by Rabbitgoo on Amazon. They are different sizes and prices so I haven’t put a specific link. The description of the one I bought is: Thick Whiteboard Chalkboard Wall Sticker 44.5cm×200cm Thickness:0.18mm

322. Accessing Quadratics

If you teach in the UK and haven’t used the excellent Access Maths site, why not?

Seriously, you are missing out!

I’ve used and recommended to colleagues lots of the Access Maths resources. This is the latest worksheet I’ve downloaded (click on the image to link to the 9-1 GCSE resource page):

I used these pentagonal problems (I believe they are know in pedagogical circles as ‘Fox Diagrams’ – but you try Googling that term and not getting a page of pictures of foxes) with my GCSE class as a two part homework. The first homework was to do the outside skills – if they felt confident they could skip questions, if they needed help they should come and see me. I stressed that they would need to use these techniques to part two and it was their responsibility to make sure they were ready. Part two of the homework was to complete the middle ‘exam’ question in their books in their books, showing the full method.

I actually enjoyed marking this homework as it gave me an insight into how they visualised problems – there were at least four different ways to complete this task. Unusually I made any low achieving student come back and redo their homework in an informal detention. By spending a few minutes reflecting on the skills they’d already practised (or should have practised), every student jumped from 0 or 10% to 100% correct. I did little more than point out where their technique had started to fail them. These students left the extra maths session with big smiles and a sense of achievement.

Inspired by the talented @AccessMaths (you really should follow them on Twitter) I’ve done my own triangular resource on expanding, factorising and solving quadratic equations.
