Algebra 1 Resources

A special thanks to the PA LEADS districts, and particularly the School District of Haverford Township, for initiating the Algebra 1 Resource page and for contributing to the contents. Keystone Exams are end-of-course assessments that were developed to measure a student’s level of proficiency in core subjects, such as Algebra I, Biology and Literature. This page contains Algebra 1 materials that align with the Keystone Exam, providing instructional content for educators and subject-specific activities that students can use to prepare for the assessment.
