Context of the Standard

Scientists, computer scientists, mathematicians, and programmers construct and use models to better conceptualize and understand phenomena under investigation or to develop a possible solution to a proposed problem. Models include diagrams, physical replicas, mathematical representations, analogies, and computer simulations. Models are used to represent a system (or parts of a system) under study, to aid in the development of questions and explanations, to generate data that can be used to make predictions, and to communicate ideas to others.

In second grade, students are expected to create simple models. These models may be created using a computing device.

Students should demonstrate these skills:

• Create a model of an object or process both individually and as a class.
• Compare and contrast attributes of a model.

Students should investigate these concepts:

• What are examples of models that we see and use regularly?
• What are examples of things in the world that you can model?
• What kinds of things do you need to know before you begin to make a model?

Students should be introduced to these concepts:
