2S - Maths: describing 3D shapes

Lesson: Maths

Today we began learning about 3D shapes.

We learnt that 3D shapes have depth and you can pick them up, unlike 2D shapes which are flat with no depth at all and therefore cannot be picked up.

We thought about the 3D shapes we see and use in everyday life and identified some of these eg. Cylinder (mug, glass beaker, glue stick), cuboid (bricks, tissue boxes, box of chocolates, TV), cone (party hate, traffic cone) etc.

We then discussed how we could describe the appearance of these 3D shapes by their faces. We used languages such as 'flat' and 'curved' to describe the faces as well as identifying the 2D shapes of the flat faces eg. A cone has 2 faces; 1 curved face and 1 flat circlular face.
