Thanks to the amazing Jo Morgan (@mathsjem) I found some great resources through her resourceaholic blog – specifically these Pythagoras problems from The Chalk Face and Spiderbox and this problem from Illustrative Mathematics.

I cut the problems up and put one on each pair of desks. The girls were allowed to work in pairs and simply had to present me with as many correct answers as they could in one hour. They had 3 ‘hint’ tokens that they could trade in for help at any point.

I was really pleased with how they worked, one pair even manged five correct solutions in the time allowed. What was great was how persistent they were about going back and trying again and again if they got it wrong – something they would never do under usual circumstances!

My group have only just learnt Pythagoras’ Theorem, but this is something you could bring out for revision with older classes as well.

Let’s start at the beginning. This term, I have been using the hour lesson that I have with top set Year 8 on a Tuesday as “Technology Tuesday”. We have had a go with Socrative, Educreations, Dan Meyer’s Three Act Maths…all good fun. Onto this moment of inspiration then.

I know, I thought, we’ll consolidate the work we’ve been doing on straight lines with a treasure hunt around the school! There can be QR codes, and passwords, and problems – it will be wonderful! I mapped it out on the back of an envelope – from the library, to the house room, to the picnic tables. There must be different start points so they aren’t all running around in one big group! The QR codes must be password protected so they can’t move on to the next problem unless they have solved the previous one!

Foolish, foolish, Mrs O’Clee…

The main trouble was that this was *complicated to plan*, and complicated things take *time*. A lot more time than I thought! (Probably 3/4 hours planning in total!). The concept was as follows:

- The students have a booklet.
- They solve the first page, giving them a password. Also on the first page is a QR code which gives them the clue to their first location. (There were 3 variations of page 1 therefore 3 different start points)
- Upon arriving at the location, they find a QR code and a clue to the next location.
- They scan the QR code (password protected) and enter the password they have just found. This then leads them to a problem. They solve the problem to get the next password.
- They move on to the next location.
- And repeat.

So what went right?

Well, I was really pleased with the immediate engagement from the girls – they loved running round the school and solving the problems. I told them to be back 5 minutes before the end of the lesson, and they were all 5 minutes late because they wanted to *just do one more*.

But what went wrong?

The password protected QR codes were a bit of a disaster. If they entered the wrong password 3 times it seemed to lock them out completely, so they all came running back to my room and we had to swap their ipad for a different one that hadn’t been locked out. Perhaps I was missing something, but password protected QR codes are a big fat no-no for my future (plus I had to take out a trial subscription for the privilege of creating the password protected QRs in the first place! A whole $3.95 wasted…)

Of course, that was just my opinion. So today I asked the girls for their feedback. And they LOVED the passwords. Yes, even though they were an absolute pain and at least half of them had issues, they were adamant that they did not want to lose the passwords if we were to do this again. They loved that they had to ‘unlock’ the next problem. I might have to think up a compromise there, because I’ve pretty much had it with password-protected QRs! Perhaps solving the problem gives them a word that completes a URL (maybe a padlet wall) and that leads them to the next location instead?

Other (sensible) suggestions included only sending them to places where they could sit and do workings out, as it was tricky figuring out the problem when they were stood outside next to a wall! Half wanted the clues more spread out, half wanted them less spread out so that was helpful.

I think I will spend a day or two just amending and improving the resources to incorporate those issues before sharing. If you’re interested in seeing them please leave me a comment!

I say first lesson, we had actually used a previous lesson for familiarisation. Thanks to Neil for all the ideas!

- Ground rules. Starting each lesson closing all open apps and clearing the history. That way if you suspect anyone is messing around you can check to see if they have any apps open that they shouldn’t. I also warned them that misuse of the iPad would result in them losing the use of it for that lesson.
- Introduction to the various sites/apps we would use – Padlet, Socrative, QR codes, Educreations (including them setting up a free Educreations account).
- When I’m talking, iPads are on the desk with the covers closed.

In the main lesson itself I used one of Dan Meyer’s Three Act Math problems – The Domino Skyscraper in particular.

We used Padlet for students to pose an initial question, and to make their guesses about how many dominos they thought it would take to knock over the Empire State Building. I think next time I may use Socrative for this and then see which I prefer.

I then let them loose on Google and Educreations. Initially, I thought it would be nice if they researched the height of the Empire State building themselves, but inevitably a couple of them Googled ‘domino’ and ‘skyscraper’ and found the answer which somewhat spoiled it! Next time, give them the information they might need and they can stay off Google, methinks!

Problems? Well, **time** first and foremost. Many of them didn’t finish their Educreations video, and very few managed to send the link to me so I could see what they had done. And as the iPads are not their own, I’m now faced with starting the next lesson dishing out the iPads just so they can log in to Educreations and send me what they’ve done. Next time I will endeavor to make sure this is all done before the lesson end so I can review all their work before the next lesson, and show the best few next time.

Also, the girls are not all using Educreations to show the journey they took to the answer, but just giving their answer much like they would on a piece of paper. Hopefully, in time, they will use the technology to show their thoughts and how they got from A to B.

Once again, I am reaching the conclusion that iPads will not **truly** change the way I teach until the kids have their own iPad for use at school and at home.

PS. A slightly unforeseen problem when we were using Padlet – clearly some of the boys in a previous lesson (possibly a sexist assumption but I’m sticking to it) had created some shortcuts. One poor girl, whenever she typed in ‘the’, it was replaced by a string of expletives. And we were on Padlet at the time, which flashes up on everyone’s iPad in real time….well, you get the idea. (For the record, Settings>General>Keyboard will take you to shortcuts, then swipe to delete.)
