This Precalculus course is one in which students:

  • Use functions, equations, sequences, series, vectors, and limits as tools to express generalizations and to analyze and understand a variety of mathematical relationships and real-world phenomena
  • Expand and develop their use of functions and their properties to choose appropriate models for real-world problem situations to answer meaningful questions
  • Build on and expand their experiences with functions from Algebra I, Algebra II, and Geometry as they continue to explore the characteristics and behavior of functions (including rate of change and limits), and the most important families of functions that model real-world phenomena, especially transcendental functions
  • Extend their work in functions, including polynomial, rational, radical, exponential, power, logarithmic, and trigonometric functions
  • Continue to work with operations on functions, including composition of functions

Rigorous Core Instruction

Our research-based approach to instruction deepens students’ commitment to learning, encouraging their effort and persistence in the face of academic challenge.

Our curriculum includes:

  • Conceptually-based lessons with real-world contexts emphasizing problem solving and critical thinking
  • Visually rich animations and simulations in each lesson designed to deepen understanding of central concepts
  • Multiple representations of mathematical relationships that engage more students and help develop stronger and more flexible understandings
  • Interactive formative assessment items and practice sets with guided hints and feedback that increase engagement and personalize learning outside of class
  • Preparation for high stakes assessments with both automatically graded and open-response questions
  • Real-time reporting of progress that allows students to take responsibility for their own learning

Robust Supports for Teachers

In addition to Internet-delivered services, educators and administrators also receive face-to-face seminars, mentoring, and high-quality support materials to help them manage their demanding workloads, enhance their expertise, and dramatically improve outcomes for their students.

Supports for teachers include:

  • Research-based, standards-aligned instructional resources, enriched by visualizations of key mathematical concepts that increase student engagement and learning
  • Formative assessment tools that provide rapid feedback with real-time reporting
  • Online and face-to-face professional development seminars and mentoring directly tied to practice
  • Day-by-day lesson support with advice and classroom strategies, equipping teachers to enact each day of instruction to achieve success for all students


Collaboration with Leading Educational Research Center

Our mathematics and academic youth programs are developed in collaboration with the Charles A. Dana Center at The University of Texas at Austin. Working with leading educators throughout the country, we have developed mathematics programs for middle school, Algebra I, Geometry, Algebra II, Precalculus, Calculus, and AP Statistics. These programs build on the Dana Center’s trusted work with more than 100,000 teachers over the past decade and on the core belief that all students can succeed in mathematics if given the opportunity.
