Zeroing in on Math

A staggering 2/3 of Boston Public School eighth graders are not proficient in math. This is a quiet crisis in Boston schools as math proficiency indicates student readiness for high school academics, forms the foundation of skills for STEM study, and predicts post-secondary success.

EdVestors set out to dramatically improve student achievement in middle grades (3-8) math by launching Zeroing in on Math (ZioM), a multi-year, city-wide initiative in 2015.

After just two years, we’re seeing powerful results. Across the 16 participating schools, students are averaging gains in math knowledge and skills of 1.4 grade levels vs. the expected one year of growth (as measured by the STAR Assessment)

To improve math outcomes for Boston students, we are:

  • Working with 130 teachers at 16 schools on specific math interventions—thereby reaching approximately 4,000 students with improved math practices in its third year.
  • Engaging 16 Boston math teachers as Zeroing in on Math Teaching Fellows, who are working together to identify problems in math achievement and develop teacher-led solutions with potential for scale.
  • Partnering with the Boston Public Schools Excellence for All initiative to support teachers & school leaders as they continue to grow as professionals and as they develop young mathematicians in Boston.
  • Gathering input from and engaging a broad community of teachers, school leaders, parents, professionals, and citizens who are passionate about math achievement. Share your ideas here.

“EdVestors’ intervention through tactical support, knowledge and expertise to our team has been crucial and is affecting the way we are teaching mathematics at our school. To have a strategic thought partner who is coming into our building and sharing ideas is important. We are in Year 1 and we are already seeing dramatic effects.”

Grant Seekers


As part of the Zeroing in on Math initiative, EdVestors seeks to partner with charter and district schools that are committed to improving the math achievement of their students in the middle grades, defined here as grades 3-8. Applications are now available for school partners interested in participating in the Zeroing in on Math Blended Learning Cohort, made up of educators testing blended learning interventions with students. Cohort participants receive funding from EdVestors as well as opportunities to share their learning within the group with the goal of developing effective strategies for boosting student math achievement across multiple schools.

Additional opportunities for schools to participate in Zeroing in on Math will be announced as they become available.

Blended Learning Cohort

Participants in the Blended Learning Cohort partner with EdVestors to help better understand how technology-based or other interventions can be part of the solution for closing knowledge and skill gaps in math in grades 3-8.

Total investments per school range in size from $5,000 to $12,000 depending on the scope of the project and number of students served.

Applications for SY2018-19 are now closed.


All public schools in Boston enrolling eighth grade students, or in the process of growing to include eighth grade, are welcome to apply in spring 2018. This includes BPS district and charter schools of all types (Commonwealth charters, Horace Mann in-district, pilot, Innovation and traditional district schools). Within these schools, any grade(s) from three through eight can be the target of the school’s gap-closing plan.
