3D shape and surface area

Today I challenged the children to build a cube and calculate its surface area. They were also asked to build a structure to demonstrate their understanding of all the 2D and 3D terms we have been using.

Building the cube proved very tricky and for some the warm sunshine was a huge distraction! In the end every group managed to build a cube or cuboid. I had wanted the more able mathematician in each group to explain to their peers how to calculate SA but in the end they needed  a wee bit of support as we had only begun to learn about this yesterday.

We toured each group and compared surface areas. As we now go to the woods in the morning ( no longer able to have an early lunch) we have our snack in the woods before we leave. I find that the children associate snack with messing around time so we need to think of some rules for this time next week.
