Every student can achieve math mastery

Our math intervention programs offer middle school and high school students who are behind the support they need to master essential skills and build confidence. Reteaching every partially developed concept or skill is simply not possible or effective. HMH provides engaging digital math intervention designed to show students that they can learn math, their efforts pay off, and math has purpose in their lives.

Math 180 Gets Results

Math 180® is designed to support students in Grades 5–12 who are performing one or more years below grade level. This research-based math intervention program has been shown to help students achieve more than two times the annual expected growth.

In one year, Math 180 students experienced significant achievement growth, with an average gain of 184 Quantile measures.

Students using Math 180 in a comparison study had an average of at least 1.75x the score increase vs. non–Math 180 students.

Students in a Math 180 Digital Access study demonstrated 1.5x expected yearly average growth in mathematics.

“[Math 180] showed me how algebra can make you successful in life."
