Exploring Algebra 1 with Fathom

Grades 8–10
by Eric Kamischke, Larry Copes, and Ross Isenegger

Exploring Algebra 1 with Fathom takes students through a visual learning experience that covers everything from linear to exponential functions

Dig into Algebra with Fathom Investigations

48 blackline master activities help students investigate patterns in mathematical relationships and real-world data.

  • Working with graphs and lines of fit, students deepen their understanding of slope.
  • Using sliders for parameters, students visualize and better understand families of linear, quadratic, and exponential functions.
  • Creating simulations, students expand their understanding of probability.
  • Building models for patterns in data, students appreciate the questions that algebra can help them answer.

Students build on pre-algebra topics, such as proportions and describing data, before exploring linear equations and exponential equations, solving inequalities and systems, transforming functions, investigating higher-degree polynomials, and simulating probability.


  • Blackline activity masters organized by topic for easy matching with your curriculum
  • Extensive teacher’s notes
  • Suggestions for homework and assessments
  • Detailed answers
  • Downloadable data sets, demonstration plots, and additional resources
