Here is my Maths work for this week, to be honest it was hard because I don't quite like Maths and Ratios wasn't one of the best things I am good at. Some of the questions tricked me into thinking it was wrong, but soon rather then later Ms Thompson helped me and she made it clear on how to understand ratios.
With a better and clearer understanding, I was able to help others with their questions. I didn't work on this alone, I was accompanied by Demetrius and George, both in which are Year 7's. They helped me answer some of the questions but again they were learning that as older children of the school we must finish our work to a high standard.
A challenge I came across was when I didn't quite understand the ratio's, but I was helped and now I think I have a better understanding of them.
My next learning steps are to learn more about ratios.
