About IMP

The Interactive Mathematics Program (IMP) is a comprehensive program of problem-based mathematics that integrates traditional material, such as algebra, geometry, and trigonometry, with important topics such as statistics and probability. Developed collaboratively by mathematicians, teachers, and teacher educators, IMP’s four-year core curriculum prepares students for standardized tests and gives them problem-solving skills they will need in higher education and on the job. Based on current research on learning, the program was published after more than ten years of research, pilot tests, evaluation, field tests, revision, and detailed reviews by professionals in the field.

OCSA has been using IMP since the 2008-09 school year and makes 5 points of distinction between IMP and the traditional math sequence:

  • Integration of topics: The traditional sequence is Algebra I  >  Geometry  >  Algebra II  >  Trig/Math Analysis or Pre-Cal. The integrated sequence that IMP uses takes content from those courses and covers material from each of them each year.
  • Problem-based: Concepts in the traditional sequence are organized by chapters (~12 per year).  Concepts in IMP are grouped by thematic units (5 per year). See this page for examples of these engaging units. A side effect of this thematic grouping is that many students are more engaged in the content of their math class.
  • Focus on communication: There is a great deal of focus in the program on the writing, reading, and oral communication of mathematical ideas.
  • Deeper look into concepts: In the traditional sequence, many standards are covered in Algebra I and then repeated again in Algebra 2 and then again in Trig/MA or Pre-Cal (at a more difficult level). Because of the way content is grouped in IMP, there is more room to develop advanced topics not covered in the traditional sequence. These topics include: discrete mathematics, matrix algebra, linear programming, curve-fitting, the conceptual basics of calculus, and…
  • Statistics: Because of the organizational grouping of standards, there is room for multiple statistics units.  In fact, a student taking 4 years of IMP would cover the equivalent of an entire statistics course.
