My eldest daughter has been getting maths homework for a year or two now. We try and do the homework together and I try and make it fun but it’s hard. It’s hard because if she doesn’t understand something by the second time I explain it, then to her I become like the teacher in Charlie Brown. Blah Blah Blah. This is especially true if when I’m explaining elementary mathematics, I make a mistake in my explanation. This happens often and only causes to confuse her royally.
And so it was with the topic of number bonds. My wife discovered, by attending a parent’s maths workshop at the school, that the children were learning that certain numbers in base 10 arithmetic are bonded. The bonds are simply as follows:
It’s fairly trivial but also fairly powerful in that once you know these bonds it’s a shortcut for mental arithmetic. We, as adults, know these ‘bonds’ so well that we probably don’t even recognise that we use them. The challenge then is to teach children this trick and thereby speed up their arithmetic ability.
One of the techniques that my daughter’s school uses is to send home ‘games’ that try and reinforce the learning they have done in the class. These games usually consist of a laminated sheet of instructions, a dice or two or other simple props. Usually these games are quite good and instructive. Some times they are totally confusing because they are meant to reinforce what was learnt in class and that doesn’t come across in the instructions. You’d think that I could ask my daughter to explain ‘how’ they should be doing it. It doesn’t work. Kids just aren’t that ‘meta’, that’s why they’re so much fun.
Now I have observed both my children playing on friv and Club Penguin. They are totally immersed in the most crappy Flash apps (although I have to say that most of them are actually quite fun!). So I thought I’d try and see if I could make a Flash game that would teach a little mathematics.
A while ago an ex-colleague posted about a super-cool Flash application he’d made. From that I figured out I could download the SDK and most of what I needed for free. However I thought I’d try the 60-day trial of Flex Builder. The added comfort of Flex builder is that it’s a pre-configured Eclipse for building Flash apps, so progress is pretty smooth-and-fast. Not sure I’d spend the $299 for a personal license though. It’s not that good.
And so the unimaginatively titled ‘Number Bonds’ was born. Enjoy.
