## Key Idea: Geometric figures, number sequences, graphs, diagrams, sketches, number lines, maps, and oral and written descriptions can be used to represent objects, events, and processes in the real world.

*Students are expected to know that**:*

- The term
*model*refers to a representation of something in the real world. - Models can represent objects.
- Models can represent events or processes.
- Geometric figures, diagrams, sketches, and maps can be used as models.
- Number sequences and graphs can be used as models.
- Oral and written descriptions can be used as models.

*Boundaries*:

- Students are not expected to know that simulations are examples of models.
- Students are not expected to know that mathematical statements or symbolic equations are examples of models.
