91. Scouting for Symmetry

This week a relative joined the Scout Association in Wales. I knew that welsh scouts wore ‘Y Ddraig Goch’ (The Red Dragon or Welsh Flag) on their uniform. I didn’t know they wore it on each sleeve, symmetrically:

This gave me the idea for a symmetry homework.

If you look at the uniformed services and uniformed youth movements, how often does symmetry occur in their badges? Do some badge styles occur in several associations? Are some images deliberately stylised to make them symmetrical? Are repeated emblems always placed symmetrically on either side of a uniform?

Pupils could also design their own symmetrical class reward badges.

From a pastoral point of view, this would be a nice way to celebrate younger pupils’ interests outside school.

90. Gadget of the Day 2

Those of a slighty OCD clean-freak nature will love this:

It’s a microfibre cleaning/dusting mitt. And it’s brilliant for cleaning the whiteboard with. No smears or marker stains! You don’t need to worry about looking a fool using it – you’ll never get the chance. My pupils argue over who wears it and gets to clean the board. It’s also washable, which makes it a bit more eco-friendly.

This one was from JML and I bought it from Asda for £2.99. You can get them from Amazon, ebay, JML etc.

89. What’s going on?

A few days ago I mentioned on Twitter that I was up to something. That something was expanding the Maths Sandpit from readable blog to downloadable resource. There are now resources available on YouTube and TES resources.

Over the next couple of months I am going to go back over my blog posts and add some related resources to the appropriate sites. I hope you find them useful.

The activity SimCon now has resources on the Tes Resources site.

87. QR teaching

Revision is a tricky business! Everyone needs something different – it is the ultimate manifestation of personalised learning.

As you will have seen from previous posts I’m not averse to chopping up exam papers or using technology to make things interesting. I also recommend YouTube videos for different revision topics.

This week I started printing QR codes, linking to online resources, onto stickers and attaching them to worksheets/books.

All pupils need is a smartphone/ipad with a barcode scanner installed. They can access the extra material whenever it is appropriate and the alternative explanations can be useful. It also helps keep pupils on task while you are helping others.

I used QRstuff.com as you can print directly to stickers (you can download them as .png files too), however there are many other sites available. If you scan the QR code above, you can access the QRstuff site too.

86. Snapdragon & Resources

I’ve just started sharing resources on the Times Educational Supplement (TES) website.

The first resource is a typed up version of the Trigonometry Snapdragon.

I’ve omitted the diagrams so you can have a discussion about what the different situations look like.

Update: I am hosting my own resources now so you can download the snapdragon here: Trigonometry snapdragon v2

 

85. App of the day: Smart Tools

Smart tools was described by one reviewer as the ‘swiss army knife’ of apps. I think I agree!

You can measure distance, angles, direction, height, sound, vibration, bearings and even turn your phone into a torch, spirit level or a magnifying glass! It’s very handy for practical activities outside. The set up for different measuring elements gives you the maths behind the result too.

I’ve used it to do bearings activities and treasure hunts. I’ve also used the height measuring mode as an introduction to pythagoras.

Individual elements can be purchased separately for free or 65p (correct at time of publishing) each. Or you can download everything in one go. Search for ‘smart tools’ on the Play store or go to: Smart tools website
