Two-Dimensional and Three-Dimensional Shapes

Overview

Your student will be learning:

• how to identify two-dimensional shapes, including circles, triangles, rectangles, and squares, which are special rectangles.
• how to sort, classify, and compare 2-D shapes by their different characteristics (number of sides, number of vertices, etc.)
• how a shape is the same regardless of its size or position.
  • Example: These are all still triangles because they both have 3 vertices (corners) and 3 sides.

• how to identify and compare three-dimensional objects (solid figures), including cylinders, cones, spheres, and cubes.
• the differences between two-dimensional and three-dimensional figures.
