Wai Maths Online Problem Solving

8 men and 2 boys need to cross a river. They have a canoe which cannot carry more than 1 man or 2 boys at one time. How many river crossing does it take to get everyone across?

We decided to enter the Wai Math's Competition, the area that we decided to concentrate on was the video section. Coming up with an idea that was going to be 'Mathematically Themed' and interesting turned out to be challenging. I had to stress to the students the need to think about 'wow'. The concept changed during the course of the 'networking' process. The original idea was to see how students/people around the world would solve the problem so we could focus on identifying the strategy. Pretty much everyone that we saw right from the start did the same thing, they used resources to work through it. I don't think that the answer, once materials were used was particularly challenging. So at this point it was more or less foundering, as the original point was getting lost in the fact that a) everyone was getting the right answer b) the method that was used involved using materials to represent the Canoe and the students and the adults. Grasping for ideas I spoke to the main student and asked him to estimate how far that the problem would travel there and back, he said 500km, at that point I had no idea myself what so ever but I thought the estimate was on the 'low' side. As it turned out it was because later that day Mr Mac from Australia (Ulearn 2009) delivered a video which meant that the question had already travelled 2,500km one way. I'm still a little wary at this point if we've created truly a 'Maths' question, although I hope that the Judges will see it as that (its due next Wednesday) rather than an ICT question. The other issue that I have to resolve is the way to green screen it. I've got a limited ability myself and also restricted to Moviemaker for production purposes. At this point I've decided that the best solution is to show each of the videos from the other classroom/countries on the data projector with Bradley talking about each one and physically standing in-front of the screen and talking. We'd then edit down considerably and take the highlights, put it all together and have something in the three minute range (maximum of five minutes for the competition).

This is our 27th July Update with the links to the various class pages with links:
It started with an idea about a Mathematical Problem and solving it for the Wai Maths Video Competition, the idea being that we're looking at different ways to problem solve an answer. We're also keeping track of how far the question 'travels' and comes back in two weeks that we have to create our video, totalling the distance. Bradley's estimation for the distance that is travelled is 500 kilometres.

We've had our first answer from Otrohonga in the King Country from Otewa School, their answer is here - a distance of 60 kilometres (120 round trip), we also had it answered from Bairds Mainfrieght Primary School in Otara, Auckland (200 kilometre round trip) and we've just had another answer from New Zealand from the BestLittleClassinNZ! - Broadlands School in Reporoa.

Just today we have a video message from Mr Mac's Classroom in Australia, that meant the question had travelled another 5,000km there and back! We've still got until Sunday and have more answers and more videos on the way.

Thank you SO much to everyone that's taken Bradley's question and viewed it and especially those who have taken the time to prepare an answer for us, we're really excited at this end and the journey hasn't finished yet!

Thank you also to our global audience who have been passing this question on to have more people check it out and spread the word about it. We're very excited to be entering the competition next week and look forward to having some additional problem solving taking place from around the world!

At the end of the day, where's the seperation.

I've always been very careful to make sure that there's adequate separation between my online persona related to my school work and my own personal preferences. I think this is a hugely important area related to 'Digital Integrity'. I don't believe that its appropriate for teachers to allow their personal opinions and beliefs to go into their class pages, that's just my personal thought but I strongly believe it. I see all sorts of online work that I would cause me to question the 'digital integrity' of the teacher. This site as its not specific to my class site, I see the separation as being fine. Thus me putting this video on here which I'd never do as part of my classwork or official school work is perfectly reasonable.

However I don't really think its appropriate for a teacher to put their holidays photographs up. I've only been online for a relatively short time, three years or so. I haven't seen it all but I've seen some examples that I couldn't believe. Teachers filming themselves doing the 'catch/trust' exercise into students arms (tell me where the learning intention is with that!), teachers complaining about their own school through their own class page, in a cluster that I was once part of I saw a teacher post 50-60 photographs of herself on holiday on her class page. I am not criticising these examples, although I think they range from preposterous to silly in my opinion, but there's no guideline for how people should operate online other than individual sense of right.

Poi E - Boy Inspired Video

This was never suppossed to go online. The back story of it is pretty simple. Room 14 at Melville Intermediate School had a student teacher who wanted to do something special for her classroom. I got involved because there was a missed connection when the video was finished, they wanted to put the music to match the video. They were inspired by the movie "Boy" which finishes with a music video along similar lines. I wasn't there when they filmed it, prepared it, and it only really came together thanks to an associate "Rob" who had the original song on Nature's Best, Volume Two (I'd tried locating it as a download online and couldn't find the song) my contribution was simply to publish the song, I liked the input from the students (the adults of course are the teachers) but strictly speaking it wasn't produced by my classroom. I'm not about not promoting it, so hence the decision to publish it online. A good bit of fun, I can't comment on the teaching process involved in this video as I wasn't there for the planning, all I did in this instance was facilitated the publishing of it. It took something fun and turned it into something online. Does it need polishing? Absolutely. There's a significant part of the video where the idea was to use the stage curtains as a "black" area, the student filming didn't adhere to the boundaries of the curtains, so you can clearly see the edges. We've got some students dancing out of time. In my editing defence I received fifteen minutes of footage and what was included in the video (which is about four minutes) was absolutely the best fit, I considered doing a second one but couldn't really see the point.
