Primary 5/6 have been looking at the volume of 3D cuboids as part of their Numeracy and Mathematics. After we had learned how to calculate the volume, (length x breadth x height), the challenge was for each child to make a gas mask box. They were asked to apply their knowledge, choosing from a variety of resources to help them. A few of the class found it difficult to know where to begin, and some of the children knew exactly what to do!
