SunBay Digital Mathematics

SunBay Digital Mathematics (SunBay Math) is a middle-school math intervention that integrates conceptually rich curriculum materials with technology-based dynamic representations of math concepts. The program consists of classroom-based replacement units that supplant regular math instruction over a two-week period whenever the unit content occurs in a district's pacing guide, with the goal of improving students' engagement with and understanding of core math concepts. Each unit is composed of seven to 10 investigations designed to be completed in one class period, oriented around a Predict-Check-Explain (PCE) cycle where students make predictions about mathematical situations, check their predictions with technology, and provide conceptual explanations using multiple representations. The intervention targets middle-school students in Grades 6-8 (regular and advanced classes) and focuses on core concepts including ratios and proportional relationships (Grades 6 and 7), expressions and equations (Grades 6 and 7), and functions and geometry (Grade 8). Teachers receive 1.5 days of summer professional development prior to implementing the first unit, plus an additional half-day of training prior to implementing any new unit for the first time, along with ongoing support and coaching throughout the school year. Implementation requires laptops or tablets with internet access, student workbooks, and teacher guides.
