# 358. A spatter of trig

The fabulous Mrs D (@mrsdenyer ) shared this forensics video, by crime scene analyst Matthew Steiner, on Twitter. At eight minutes in the presenter looks at blood spatter analysis. The use of basic trigonometry in a practical situation is a gift of a video for a starter in lesson.

My class were absolutely silent throughout and wanted to watch the whole video, however they may have just been trying to avoid work. I shared the video link with them via our digital classroom platform. We are now using blood spatter for 3D trigonometry examples rather then mobile phone masts. Gory, but effective!

# 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!

Subscribe to the Channel, get fit and see what your students think

Update: 1st June 2019

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

# 327. Digital Exercise books

Sorry – haven’t invented a digital Exercise book and I don’t use iPads/tablets in class. Today I’m sharing the inventiveness of my class.

I printed out one of those brilliant Corbett Maths textbook exercises to use with a Y7 class. It was a recap task, so I stressed that students could pick the level of difficulty. They cut out the sections they were doing and stuck them in their book. Because there were lots of different questions being completed, I allowed them to use their phones to scan the QR code to access the answers. A couple asked to scan the help video QR code.

I saw a few pupils being fussy about their cutting out – why were they cutting out little bits? That’s time wasting! No one should be time wasting!

Then I checked exactly what they were doing …

… The little geniuses:

They were cutting out the relevant QR codes and sticking them in their books. If this is the level of forward thinking in Year 7, they are going to fly through GCSE revision.

# 249. Reflection Worth doing

Happy New Year folks!

Just a quick post today. How to use footage from a classic 1960s show to demonstrate reflection for comedic purposes.

The classic sketch by Harry Worth. Just wait and see how many students try to copy this.

# 199. Video of the week: Constructing Pentagons

I came across this video whilst looking for 3D construction ideas for a 7 year olds homework. It is a very easy to follow video explaining how to construct a pentagon using a ruler, pencil anda  pair of compasses. When I say easy, I mean it. The voiceover is in Spanish and all my knowledge of Spanish comes from watching ‘Dora the Explorer’ with the children – and I still understood how to do this.

Not only will it help pupils improve their fine motor skills using compasses, you could also ask more able students why it works. You could also ask Spanish speakers to translate!

# 107. The Validator returns

Back in Post 72 I looked at the idea of a student validator, which had been developed by Mr Reddy (@MrReddyMaths).

View the original post here.

Well, I discussed it with my colleagues and a couple of us tried it out. It worked like a dream. Pupils of all abilities and ages took responsibility for checking work and giving advice. In fact it was so successful we have adopted it as Department. My HoD had seen ‘Peer Assessed’ stampers and ordered those as well as lanyards for everyone:

I’d like to thank Mr Reddy for sharing his idea on his blog.

If you want to introduce this concept to your pupils/staff check out my videoscribe introduction on YouTube. I’m still new to videoscribe, so it’s a bit jumpy, but the summary gets the message across.
