In the summer of 2025, TERC piloted Doing the Math with Families , an adaptation of the U.S. National Science Foundation–funded Doing the Math with Paraeducators project. This version extended the original professional development—designed to strengthen paraeducators’ math confidence, knowledge, and teaching strategies—to bilingual parents through playful, engaging math games. The following reflection was written by Zaozao (Annie) Lin who volunteered on the project. The participants recruited for this project were invited because they were either supporting the childcare for families attending English classes or they were taking English classes and expressed interest in becoming educators. Four Spanish-speaking mothers and one aunt participated in a six-week program, meeting for two hours each week to learn tools and games that support children’s math learning. Each session was co- facilitated by two bilingual former paraeducators, previous participants in the Doing the Math for Paraeducators training. Sessions focused on building caregivers’ math confidence and knowledge through concepts such as subitizing, number sense, patterns, and place value, as well as tools like number lines and hundred charts. Caregivers practiced playing TERC Investigations TM math games with their children (PreK–Grade 3) and ultimately helped lead math games for families at a Boston Public Schools back-to-school event.
