Algebra I - Module 1, Topic 2: Sequences
In this topic, students explore sequences represented as lists of numbers, in tables of values, by equations, and as graphs on the coordinate plane. Students move from an intuitive understanding of patterns to a more formal approach of representing sequences as functions. In the final lesson of the topic, students are introduced to the modeling process. Defined in four steps—Notice and Wonder, Organize and Mathematize, Predict and Analyze, and Test and Interpret—the modeling process gives students a structure for approaching real-world mathematical problems.
Algebra I - Module 1, Topic 3: Linear Regressions
In this topic, students focus on the patterns that are evident in certain data sets and use linear functions to model those patterns. Using the informal knowledge of lines of best fit that was built in previous grades, students advance their statistical methods to make predictions about real-world phenomena. They differentiate between correlation and causation, recognizing that a correlation between two quantities does not necessarily mean that there is also a causal relationship. At the end of this topic, students will synthesize what they have learned to decide whether a linear model is appropriate.

Developing the Concept of Slope
![OnTrack OnTrack logo](https://d1yqpar94jqbqm.cloudfront.net/styles/resource_icon_small/s3/images/ontrack_large_9_binder_1.png?itok=bGsrJJzj)
Given multiple representations of linear functions, the student will develop the concept of slope as a rate of change.
Generating Different Representations of Relationships
![OnTrack OnTrack logo](https://d1yqpar94jqbqm.cloudfront.net/styles/resource_icon_small/s3/images/ontrack_large_9_binder_1.png?itok=bGsrJJzj)
Given problems that include data, the student will generate different representations, such as a table, graph, equation, or verbal description.
Interpreting Scatterplots
![OnTrack OnTrack logo](https://d1yqpar94jqbqm.cloudfront.net/styles/resource_icon_small/s3/images/ontrack_large_9_binder_1.png?itok=bGsrJJzj)
Given scatterplots that represent problem situations, the student will determine if the data has strong vs weak correlation as well as positive, negative, or no correlation.
