What happened in our world? May 22nd, 2016 is a crossword based on last week's news events. It's low-calorie, high-fibre, high-interest, and nothing at all to do with SATs or Brexit. In this week's puzzle… This week... An earthquake rattled Australia’s Northern Territory, an Aussie teenager reached the top of Mt Everest and Mt Something Else erupted in Indonesia. Killing bulls was outlawed in some Spanish towns, Barcelona’s footy fans are allowed to wave the Catalan flag - if they want to - and Manchester United is probably waving goodbye to Louis. Naughty Nick overheated in the tennis again, as did some Indians when their temperature hit 51C. The World Bank set aside $500 million for pandemics. Brazil’s Zika is now in Africa and Africa’s Nile crocodile is being nasty in Florida’s Everglades while tarantulas were nasty in a plane going to Canada. Cyprus and Austria held elections. Seriously… this is not a crossword you want to miss out on (or deny your students the pleasure of). These are simple crosswords aiming to encourage our students to ask about what's happening in their world - Why did it happen and where? And most importantly, who are the people affected? As a bonus, there's a crossword asking students to name some of the elements in the periodic table. (If that's too boring, download last week's file because the bonus puzzle last week was a bit of fun with fruit and veggies). Use the crosswords in your home-room class, in subject lessons, in substitution lessons, in lunchtime or after school clubs, in the time-out room, or even in the staffroom (during a staff meeting if you dare). Keep the comments coming in - we love to hear how the crosswords are being enjoyed by you and your students.

What happened in our world? May 15th, 2016 is a delicious and nutritious crossword based on last week's news events. It's low-calorie, high-fibre, high-interest, and nothing at all to do with SATs. In this week's puzzle… New Zealand's Mt Ruapehu is grumbling and may erupt soon. Japan now has more electric car recharging places than petrol stations. Shell set up a new division all about renewable power. Ukraine won Eurovision, much to Russia's annoyance. A prehistoric whale washed up on an Australian beach. The OED added 500 new words, and removed just one (gullible). Hong Kong glued pavement bricks down so they can't be thrown by protesters. Andy beat Novak, Barca beat Granada, and Man U's game was cancelled. (And still nothing about Donald Trump because I'm hoping that if I ignore him, he'll go away). These are simple crosswords aiming to encourage our students to ask about what's happening in their world - what happened in the world? Why did it happen and where? And most importantly, who are the people affected? As a bonus, there's a crossword asking students to squish fruit and vegetables into a crossword. I wrote squish there because squash would've seemed a bit punny. Who knows, one child somewhere in the world may be inspired to eat a carrot or an orange. Why weren't oranges called greens? And tomatoes are a funny thing, aren't they? Some people hate them. Some people just hate the skin. Their pronunciation is controversial. Their spelling is iffy. And are they a fruit or veg.? Meanwhile the potato just does its humble potatoey thing. And how's thins for a clue… Orange, but not an orange. Or this one… Straw. Rasp. Black and blue. See - healthy, nutritious, non-controversial and very very cherry berry educational. Use the crosswords in your home-room class, in subject lessons, in substitution lessons, in lunchtime or after school clubs, in the time-out room, or even in the staffroom (or even in a staff meeting if you dare). This week you can even use them in the garden or orchard. Keep the comments coming in - we love to hear how the crosswords are being eaten by you and your students.

This powerpoint presentation covers PED, PES, YED, and XED and includes a section of exercises at the end. It's suitable for A Level, IBDP SL & HL, and AP Economics students. There are 90+ slides. They're clear and simple to read and include colourful images to turn a relatively dry topic into something a little more interesting. With witty teacher banter, to explain and expand on the slides, this presentation could take 3-4 weeks to proceed through. I strongly suggest working through one section and then using the accompanying crosswords (also available on my store) as a breakout activity. The presentation is ready to go, but can also be edited to suit your own situation. An extension section covering arc elasticity and a 'better' equation is suitable for the students who will study Economics at university.

What happened in our world? January 24th, 2016 is THREE crosswords based on last week's news events. In this week's puzzles… A LOT of snow fell in the US. Google did not pay a LOT of tax.

And one of Interpol's most wanted fugitives was found working in a sandwich shop near a police station. The puzzles aren't difficult and they don't require the students to have read last week's news. Indeed, they're easy to complete and hopefully they drive students to the news websites for answers to some obvious questions such as, Why are so many people fleeing Syria? Why would Russia give military hardware to Fiji? Goldman Sachs' CEO was paid how much last year? Why has so much snow fallen in the US? This week's BONUS puzzle is for GEOGRAPHY teachers (or for teachers who have to substitute for absent Geography colleagues).

A rapper was expelled from South Africa, not because they don't like rap, but because of immigration issues. Norway's government told those refugees who cycled across the Arctic border from Russia to backpedal. And the rock icon David Bowie died. Crosswords aren't just for word nerds.

These crosswords are ideal as a research, writing and reading activity. They can be completed individually or in small groups or as week-long homework activities, or even as a time-out activity. They are an excellent excuse for students to make good use of their smartphones. Maybe you could start up a lunchtime news and current events club and use these puzzles as starters for conversation topics. If you have students whose handwriting is messy… make them do crosswords because they force kids to write clearly, carefully and therefore neatly. Or (but it could also be And…) use them in the staffroom to keep the smarties quiet for a while. Peace at last!

But a catnap is… Twitter shares crashed, Huawei's revenue almost doubled, Coca Cola angered Russians and Ukrainians, and did Volkswagen's sales go up or down? Some Russians were stuck in the snow and a Russian doctor is stuck in court. Guatemala’s Fuego Volcano erupted, an Indian boy scored 1009 runs in a cricket game, and Tim Winton had a whole fish species named after him.

What happened in our world? December 20th, 2015 is TWO crosswords based on last week's news events. Better for improving spelling than a dictionary. Better for improving handwriting than any app and way better for managing attention-span issues than gummy bears (and let's be honest, there aren't many things better than gummy bears).. These crosswords are good for starting interesting discussions and debates. They can be used for homework activities. Or, in class, allocate students into groups of three, let them use their smartphones, and say very loudly, 'ready, set, go'.
