12.1. Algebra: Students continue identifying, describing, and extending numeric patterns involving all operations and nonnumeric growing or repeating patterns. Through these experiences, they develop an understanding of the use of a rule to describe a sequence of numbers or objects.
2.1. Understand patterns, relations, and functions.
2.1.1. Describe, extend, and make generalizations about geometric and numeric patterns.
2.1.2. Represent and analyze patterns and functions, using words, tables, and graphs.
2.3. Use mathematical models to represent and understand quantitative relationships.
2.3.1. Model problem situations with objects and use representations such as graphs, tables, and equations to draw conclusions.
2.4. Analyze change in various contexts.
2.4.2. Identify and describe situations with constant or varying rates of change and compare them.
