Curriculum Details

Interactive Mathematics Program’s proven content has been restructured and revised into a traditional pathway that fully meets the Common Core State Standards for Mathematics. These new courses are titled Meaningful Math and are comprised of Algebra 1, Geometry, and Algebra 2.

Interactive Mathematics Program® is one of three comprehensive high-school mathematics curricula identified as “Exemplary” by the U.S. Department of Education for providing convincing evidence of its effectiveness in multiple schools with diverse populations.

Meaningful Math Improves Student Achievement

Meaningful Math has demonstrated impressive student achievement and engagement with a problem-centered approach. Students across different ability levels showed superior performance results using a variety of measures.

Meaningful Math is Technology-Enhanced

The Meaningful Math curriculum incorporates graphing calculators as an integral part of the development of mathematical ideas. The calculators enable students to see mathematics and problem solving in a different way and allow them to focus on ideas.

Meaningful Math Books

THE OVERLAND TRAIL Students look at mid-19th-century Western migration in terms of the many linear relationships involved.

ALL ABOUT ALICE The unit starts with a model based on Lewis Carroll’s Alice’s Adventures in Wonderland, through which students develop the basic principles for working with exponents.

THE PIT AND THE PENDULUM Exploring an excerpt from this Edgar Allan Poe classic, students use data from experiments and statistical ideas, such as standard deviation, to develop a formula for the period of a pendulum.

COOKIES In their work to maximize profits for a bakery, students deepen their understanding of the relationship between equations and inequalities and their graphs.

FIREWORKS The central problem of this unit involves sending up a rocket to create a fireworks display. This unit builds on the algebraic investigations of Year 1, with a special focus on quadratic expressions, equations, and functions.
