Counting Cogs

This week, LH3 did a maths activity called Counting Cogs.

Our first step was to colour in one tooth on the paper cogs. My group was Aleena, Ash and Vrishti. We each got two. We needed to find which cog tooth fits into a empty space on the other cog prefectly. We then had a piece of paper and we wrote down which pair worked and which didn't.

Our challenge was to find which cogs fit. We found that 5 and 7 didn't work because it is times to a odd number. 6 and 8 did work because they times to a even number. So we found that even and odds mattered.

We all got help from this digital tool linked on our maths design. It lead us to this 'app' that lets us experiment with the different sized cogs. My group found it cool and really easy to work with. It helped him a lot.

We then wrote on our poster which cog pairs worked and which didn't and our 'conclusion' that we found.

I think my group worked really well. We exchanged ideas and we listened to eachother so our work became successful.

What I want to do next is to learn how the cogs work and how thy fit together. Like, is there a different why to solving it and how else could we check it instead of the timings method.

Over all, this activity was really fun and cool and it got my mind going on how the cogs worked. I also think that it was amazing to work with other people because I could exchange ideas and we could help each other. I also liked how this activity was a lot different than our other maths activity.
