Testimonials

It's harder to work through the problem than being given the answer. But when I was looking at my required college curriculum, I realized that this work helped me prepare better for college. You understand the methods for solving the problem, instead of a teacher handing you the formula. You understand why it works that way.

Senior, (4th year of CPM)

We are already seeing the benefits of the program (after 3 years). Students seem to be better prepared for higher level math courses and stronger results are showing up on various standardized tests.

Peter, Director of Curriculum and Instruction

My daughter has always struggled with mathematics. But with CPM she began to like math and really understands what she is learning. All of the hands-on learning tools, like the Algebra tiles, have really helped her to finally succeed in math class.

Parent of CPM Student

One of the main things I've heard from the teachers is that the structure of the lessons gives them the ability to quickly identify how individuals, small groups and the entire class are doing during a lesson. As a result the teachers are able to interact with students or facilitate activities to provide immediate responses. Students are less likely to fall through the cracks and students continue to progress at a productive pace.

Travis, Math Coordinator

Students are organized into study teams and work on problem-based applications, team strategies and real-world applications. Many algebra teachers feel reenergized and are having more fun teaching math with the CPM approach. Algebra classes focus on both basic skills and problem solving strategies that are used to help students relate to and understand the concepts behind the problems. Our students are being taught Algebra in a more rigorous and relevant manner. It's really about discovering the math, rather than being told the math.

What can QuickMath do?

QuickMath will automatically answer the most common problems in algebra, equations and calculus faced by high-school and college students.

• The algebra section allows you to expand, factor or simplify virtually any expression you choose. It also has commands for splitting fractions into partial fractions, combining several fractions into one and cancelling common factors within a fraction.
• The equations section lets you solve an equation or system of equations. You can usually find the exact answer or, if necessary, a numerical answer to almost any accuracy you require.
• The inequalities section lets you solve an inequality or a system of inequalities for a single variable. You can also plot inequalities in two variables.
• The calculus section will carry out differentiation as well as definite and indefinite integration.
• The matrices section contains commands for the arithmetic manipulation of matrices.
• The graphs section contains commands for plotting equations and inequalities.
• The numbers section has a percentages command for explaining the most common types of percentage problems and a section for dealing with scientific notation.
