Last week room 14 looked at some geometry problems. The first one was 'Is a square a rectangle?' They had to work in small groups to record the properties of squares, rhombuses, parallelograms and rectangles. The groups then shared their ideas and we had a discussion to try and answer our question. We also had to decide if a square was a rhombus, if a rectangle was a parallelogram etc etc. we thought about symmetry, sides and angles to help us decide. We nearly all agree that a square is a rectangle! We then moved onto 3D shapes and had to choose the odd one out from a sphere, a cylinder, a cuboid and a square based pyramid. This involved lots of discussion about the various properties of the shapes. Everyone had to apply reasoning to back up their opinion and agree on only one odd thing out in the group. Every single group decided the sphere was the odd one out. One student said any of them could be and we realised that not all problems have a right or wrong answer. Check out the videos below for some of our thinking on 3D shapes.
