Performance Expectations

The performance expectations in second grade help students formulate answers to questions such as:

  • How does land change and what are some things that cause it to change?
  • What are the different kinds of land and bodies of water?
  • How are materials similar and different from one another, and how do the properties of the materials relate to their use?
  • What do plants need to grow?
  • How many types of living things live in a place?”

Students are expected to develop an understanding of what plants need to grow and how plants depend on animals for seed dispersal and pollination. Students are also expected to compare the diversity of life in different habitats. An understanding of observable properties of materials is developed by students at this level through analysis and classification of different materials. Students are able to apply their understanding of the idea that wind and water can change the shape of the land to compare design solutions to slow or prevent such change. Students are able to use information and models to identify and represent the shapes and kinds of land and bodies of water in an area and where water is found on Earth.

Calculation Method for DCI

Disciplinary Core Ideas are larger groups of related Performance Expectations. So the Disciplinary Core Idea Grade is a calculation of all the related Performance Expectations.
