Children use their developing understanding of the three dimensions (up and down, left to right, front to back) to investigate regular and irregular two-dimensional shapes, identifying the shape’s 2 dimensions.
They identify curved lines, naming them curved lines, and straight lines, naming them sides.
They identify that sides meet at points called vertices.
Children describe two-dimensional shapes – triangles, quadrilaterals, pentagons, hexagons, octagons.
Children name a two-dimensional shape from a description of its line, side and vertex features.
