Experienced, high-quality professional development for K-5 mathematics teachers, specializing in problem-based learning models like IM Math K-5™ and Everyday Math 4th ed.

Most districts begin a new math adoption with strong enthusiasm. But after two to three years, implementation quality often wanes.

Teacher turnover, shifting priorities, and the daily demands of school life gradually erode shared practices and instructional consistency.

Brookside exists to break that cycle.

Brookside partners with school districts to sustain high-quality mathematics instruction in the years following their initial implementation. Sustaining that initial enthusiasm and eagerness to adopt best practices takes continuous learning and the desire to discover more effective approaches. Brookside exists to help districts do that.

Drawing on deep, hands-on experience supporting Illustrative Mathematics and Everyday Mathematics, Brookside provides the sustained, professional training school systems need to maintain momentum long after the first year.

We support educators through:

• 01 Ongoing workshops that deepen understanding and keep teams aligned
• 02 Classroom coaching that strengthens best practices where teaching happens and where it matters most
• 03 Custom materials that reinforce curriculum coherence
• 04 Collaborative planning that builds shared instructional vision

Brookside supports:

• — Classroom teachers
• — Math coaches and specialists
• — School and district administrators
• — Districts implementing IM Math K-5™, Everyday Mathematics 4th ed., or any problem-based learning program
• — Schools seeking long-term improvement in math instruction

Brookside-Math Education was established in 2001 by Rosanne O’Donnell.

Rosanne’s early work focused on writing and presenting training modules for Everyday Mathematics. These workshops were presented to school districts during their adoption cycle, as well as at NCTM and NCSM National Conferences.

In 2019, Rosanne was introduced to IM Math™ and became a Certified Illustrative Mathematics Facilitator for IM Math K-5™.

Across presentations and workshops — whether in one-room schoolhouses or New York City — each partnership has shaped the core insights behind Rosanne’s work.
