209. Unforgettable pens

Before signing off for the Easter break, I thought I’d share this nifty little gadget with you.

  • What do teenagers always bring to lessons? I’ll give you a hint: it’s not their homework.
  • What do teenagers often forget to bring to lessons? I’ll give you a hint: it’s not their homework.

Answers: Mobile phones are often brought, pens are often forgotten.

The ‘Jackpen‘ is a pen that fits into the standard headphone socket on a mobile phone.

It’s a clever little idea, combining two everyday essentials. The multi-packs make them cheap enough to be good classroom prizes too (pick up three pens for less than £3 from Amazon)!

 

For students it’s a bit of novelty, although it could be easy to lose or ‘borrow’ and is not a long term solution to bringing their own pen!

208. Gadget of the week

Anyone who visits or uses my classroom knows that whatever equipment you will need to teach with will be there. I think it’s just good manners to keep everything tidy when you share a classroom.

One of my pet hates is mini-whiteboards, or rather the distribution and collection of them. If you weren’t in that classroom the lesson before, you don’t have the luxury of putting them out before pupils arrive. Some people keep them in plastic wallets with a board, pen and wiper in each. Great, until:
“My pen doesn’t work!”
“There is no wiper”
“There are no wallets left”

Last year I found an easy to manage solution in a supermarket – Kids Garden tidys (£2.50 – Tesco). They are back in stock for Spring.

The long section holds whiteboards, the small section is a perfect pen pot and the middle sized section holds mini sponges. Obviously this will depend on the size of your whiteboards.

If my tables are groups, I just put one of these baskets in the middle. If the desks are in rows I distribute them around the room – it saves a rugby scrum at the front. Collecting the boards in is much quicker and it is easy to have a couple of spare pens in each tidy in case one runs out.

The small size of these baskets makes them easier to store than the full size versions. As they have handles, they stack nicely when not in use. They could also be used for any class equipment: pencils, calculators and rulers maybe?

See what your local garden centre or supermarket has this Spring and have a Spring clean of your teaching space!

203. Sunny Surd Sunflower

Today we have a guest contributor to the Sandpit – my colleague BH.

His Year 9 class have been studying Surds. They have just completed two particularly difficult Tarsia puzzles on simplifying surds. He celebrated their success by getting the class to create a ‘Sunny Surd Sunflower’ – what a great way to celebrate springtime and achievement.

UPDATE: Inspired by the bright sunflower, my class created an AVERAGE caterpillar!

201. BBC Crispies

There was an interesting discussion on the BBC Breakfast programme this morning about the exchange of maths teaching ideas between British and Chinese teachers.

The guests on the sofa were from the NCETM and a serving Head of Maths. There was mention of the innovative ideas used to teach Maths in Britain – including some of mine. I’m not being presumptive, I happen to know that Head of Maths – in fact some of his ideas are on this site (JDs Tree Diagrams). So just in case you missed Breakfast, here is some Cake.

 

200. Website/Resource of the week 4

Wow! This is proper blog post number 200. How should I mark this occasion? Why, by recommending another splendid site of course!

To quote the folks themselves: JustMaths is born from the passion and spirit of three full time teachers at the “most improved school in England” (January 2013).

The site has both free and subscription resources. The latest initiative is the ‘Bread & Butter’ worksheets. It consists of straight-forward starter worksheets to practice essential skills for students: Just Maths: Bread & Butter. My class use them every lesson and I’ve noticed a real improvement in their confidence and quality of solutions in just two weeks.

197. £40.95

Today we have a discussion starter question for you, inspired by a trip to the shops.

image

My shopping cost £40.95 today. What is the smallest number of coins required to make this amount?
If I paid with two £20s and a £10 note, what is the most efficient change?
Why would someone pay £41.05, as opposed to £41?

I purchased 17 items, do you have enough information to calculate the mean?
The most expensive item was £10, the cheapest was 45p. What does this allow you to calculate?
Two luxury items cost £9 in total. If I hadn’t bought these, what would the mean have been? Does this effect the range?

When I paid I was given this voucher:

What would the shopping have cost somewhere else?
What would the mean cost per item be after this discount?
What percentage discount is this?

You could also use this as a discussion starter about the number skills you use when you go shopping.

196. Gadget of the day 6

It’s been a while since I’ve had a gadget of the day. Today is more of a stationary item of the day. I’m a fan a moleskine books and the number of index markers mine have hanging out of them is a standing joke.

image

Now I’ve discovered Leuchtturm 1917 books.

image

Just like basic moleskine books they come in plain, lined and squared paper versions. Just like moleskine they are hardback, have an elastic closure and wallet in the back cover.

image

Unlike moleskine books, they have a blank index and every page is numbered. This makes finding specific notes really easy and doesn’t require excessive sticky tabs. You can also get pen loops, so you don’t lose your favourite pen. I definitely think my notes look more professional/organised now: Left has 17 sticky tabs, right has an index.

You can purchase both moleskine and Leuchtturm books from most big stationers or online.
