We have been learning all about different 3-D shapes in Maths, particularly cubes, cuboids, cylinders, spheres, pyramids, square pyramids, triangular pyramids, triangular prisms etc. We can count the faces, corners (or vertices), and sides of each shape and have experimented with which 3-d shapes can or can't roll. The shapes without any corners can roll easily.We also are very good at identifying different 3-d shapes in the environment. We love playing a shape game in class, where teacher puts a selection of 3-d shapes in a bag and describes its properties (e.g. it has 6 faces and all of them are squares, 12 sides and 8 corners) and we have to guess the shape teacher is talking about. We also take turns describing a shape from the bag (which we can feel but cannot see!!!) and the rest of the class have to guess the shape. We also made some cubes using marshmallows and cocktail sticks!! We had to think carefully about the number of faces, sides and corners of a cube.
