Year 3 students, using virtual technology, investigated, manipulated, transformed and even translated solid geometrical objects such as a cube, cylinder, pyramid, sphere, cone and triangular prism in their maths session today. Students used the hollowed , cut paths, twisted, sheared tools whilst also learning to use the camera controls to help give them perspective when creating their objects - the camera assisted with top view, side view and front view.
MA2-14MG makes, compares, sketches and names three-dimensional objects, including prisms, pyramids, cylinders, cones and spheres, and describes their features
Make models of three-dimensional objects and describe key features (ACMMG063)
- identify and name three-dimensional objects as prisms (including cubes), pyramids, cylinders, cones and spheres
- recognise and describe the use of three-dimensional objects in a variety of contexts, eg buildings, packaging (Communicating)
- describe and compare curved surfaces and flat surfaces of cylinders, cones and spheres, and faces, edges and vertices of prisms (including cubes) and pyramids
- describe similarities and differences between prisms (including cubes), pyramids, cylinders, cones and spheres (Communicating)
Students should be able to communicate using the following language: object, two-dimensional shape (2D shape), three-dimensional object (3D object), cone, cube, cylinder, prism, pyramid, sphere, surface, flat surface, curved surface, face, edge, vertex (vertices), net.
In geometry, the term ‘face’ refers to a flat surface with only straight edges, as in prisms and pyramids, eg a cube has six faces. Curved surfaces, such as those found in cylinders, cones and spheres, are not classified as ‘faces’. Similarly, flat surfaces with curved boundaries, such as the circular surfaces of cylinders and cones, are not ‘faces’.
The term ‘shape’ refers to a two-dimensional figure. The term ‘object’ refers to a three-dimensional figure.
