Standard 13: Patterns and Relationships

In grades K-4, the curriculum should include the study of patterns and
relationships so that students can:

Recognize, describe, extend, and create a wide variety of patterns

Similar patterns may show up in many places in nature and in the things
people make.

Things change in some ways and stay the same in some ways.

Some events in nature have a repeating pattern. The weather changes
some from day to day, but things such as temperature and rain (or snow)
tend to be high, low, or medium in the same months every year.

Sometimes changing something causes changes in something else. In some
situations, changing the same thing in the same way has the same result.

Tables and graphs can show how values of one quantity are related to
values of another.

Explore the use of variables and open sentences to express relationships

Mathematical statements using symbols may be true only when the symbols
are replaced by certain numbers.
