Year 4 & 2 joined together to complete a maths investigation about perimeter. First the children had to think of ways of measuring around the hall without using any standard measurements. The children discovered that their measurements all differed. Then they were given a variety of standard units of measurement to use such as rulers, meter sticks and tape measures. The children noticed that although their measurements were similar they still differed due to a variety of factors. They all agreed that a trundle wheel would be the best option and they discovered that their measurements were accurate. We then asked the children to use the information they had about the perimeter to calculate the area of the hall. The groups were mixed year groups and they all had fun working together.
