# GM3-4: Represent objects with drawings and models.

This means students will make drawings of objects, which can take the form of plan views or nets.

Note that a net is a flat shape that folds to form a solid. Many different nets form the same solid, for example there are eleven different nets that form a cube. At Level Three students need to create two-dimensional drawings of three-dimensional models, as above, and be able to recreate the model when given another person’s drawings of it. Models may be built with interlocking cubes, plasticine, connecting geometric shapes or other materials, for example toothpicks and plasticine.
