NGSS Science and Engineering Practices. 2 – Developing and Using Models. K-2. Modeling in K-2 builds on prior knowledge and processes to include using and developing models. Develop and/or use a model to represent amounts, relationships, relative scales, and/or patterns in the natural and designed worlds.

NGSS Crosscutting Concepts. 4 – Systems and System Models. K-2. Objects and organisms can be described in terms of their parts.

NGSS Crosscutting Concepts. 6 – Structure and Function. K-2. The Shape and stability of structures of natural and designed objects are related to their function(s).
