Maths - Cogs

What - Today we had to continue our collaborative maths about cogs and the learning intention was to work together collaboratively. In our groups we all have our own roles and I will explain my role.

So What - For our cog activity we had to colour one tooth on the cog and then figure out which pairs (of cog) would go / fit together in each slot and what we would clarify or call the cog as was the amount of teeth each cog would have for example a cog with 3 tooth would be called or clarified as "3". A pair of cogs that would fit together is 4,5 and also 5,6. A way that our habitat found to know which ones would work together was if you put an even number and another even number together it would work and a even and odd together, it would also work but if you put odd and odd together it wouldn't work and the reason is that if you do even times another even number it would be even and odd and even would also be even but if you times two odd numbers together it wouldn't work because the sum is an odd number. At first I found it difficult but once the learning coach told us the way I just told you it was easier. Now I'll explain my role. My role is called "Questioner/Includer". The includer bit is my secondary job / role and if anyone is away i will be their substitute. Now for the questioner. (Not Finished)
