Grade 7 OER Math, Edition 1
You can find the most recent version of the materials at Bluebonnet Learning™ Grade 7 Math.
These OER Secondary Math instructional materials were submitted to the Texas State Board of Education for review as part of their annual Instructional Materials Review and Approval (IMRA) process in May 2024. These materials have been revised to reflect updates from the SBOE IMRA process and public comments and feedback.
The revised materials, now called Bluebonnet Learning Secondary Mathematics, can be found on the Texas Gateway at https://texasgateway.org/book/bluebonnet-learningtm-seventh-grade-secondary-mathematics-edition-1. Please see Bluebonnet Learning Secondary Mathematics for the most updated version of these instructional materials.
8.01 Conic Sections

8.06 Polar Graphs
In this video, students will learn how to graph polar curves.
8.07 Special Polar Graphs
In this video, students will learn the equations and graphs of special polar curves.
8.04 Parametric Equations
In this video, students will learn about parametric equations, how to sketch parametric curves, and the differences between parametric curves and rectangular graphs.
Pilot Algebra I
In this course, students will build understanding of the following modules: Searching for Patterns, Exploring Constant Change, Investigating Growth and Decay, and Maximizing and Minimizing.
Each module is broken up into topics where you will find teacher materials to guide the instruction and the student materials both used in the classroom for learning together and learning individually.
The agency developed these learning resources as a contingency option for school districts during COVID. All resources are optional. Prior to publication, materials go through a rigorous third-party review. Review criteria include TEKS alignment, support for all learners, progress monitoring, implementation supports, and more. Products also are subject to a focus group of Texas educators.
Algebra I - Module 1, Topic 1: Quantities and Relationships
In this topic, students explore a variety of different functions. The intent is merely to introduce these new functions, providing an overview but not a deep understanding at this point. The topic is designed to help students recognize that different function families have different key characteristics. In later study in this course, they will formalize their understanding of the defining characteristics of each type of function.
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.
