Hello, I have an interview next week for a Key Stage 2 post. In my interview I have been asked to choose an area of Numeracy that will need to be taught to a group of 6 Year 5 children for 20 minutes. I have chosen to concentrate on the area of measures, as I think this will be very practical for the children, but I am having a bit of trouble where to start with my activity. I want children to measure accurately to create a string stick man from measurements that they have been given. The teaching being that we are thinking about how we measure accurately and what tools it would be appropriate to use. E.G A ruler or a metre stick. I feel that this is too simple though and was wondering whether to bring conversions into this activity and get children to convert the measurements for the stick man before they start measuring and building him. My problem with this though is that I only have 20 minutes to do this in and I don't think there would be enough time to do all of this during that time. Should I concentrate on the conversions or just the accurate measuring? If I just concentrate on converting measurements how can I make this meaningful for children? Any advice would be very appreciated.
