What you’ll learn

  1. Naming 2D ShapesName and classify 2D shapes, including quadrilaterals and types of triangle.2D shapes are flat, with length and width but no thickness. Four-sided shapes are quadrilaterals (squares, rectangles, rhombuses). Triangles are classed by their sides: equilateral (3 equal), isosceles (2 equal) and scalene (all different).
  2. Exploring 3D ShapesName 3D solids and count their faces, edges and vertices.3D shapes are solid, with length, width and depth. They have faces (flat surfaces), edges (where faces meet) and vertices (corners). A cube has 6 faces, 12 edges and 8 vertices; a sphere has no vertices at all.
  3. Drawing and SortingUse nets to link 2D and 3D shapes, and sort shapes into flat 2D and solid 3D.A net is a flat pattern that folds into a 3D solid — six squares fold into a cube. The key difference is that 2D shapes are flat and can only be drawn, while 3D shapes are solid and can be held.
