About Us
The Mathematics Unit at the Los Angeles County Office of Education supports student achievement by cultivating the joy in mathematics through high quality professional development, coaching, consultation and technical assistance to Local Educational Agencies across Los Angeles County.
The math unit; models active engagement through an assets based approach that focuses on culturally and personally relevant instruction, focuses work on equitable access and opportunity so each and every Los Angeles County student cultivates robust mathematical identities and become powerful doers of mathematics and provides educators opportunities to network and nurture their own mathematical identity to be facilitators of learning and advocates for students!
"Math is more than just a way to describe the world, and it is more than just a set of skills, like doing arithmetic or factoring a quadratic. Math is a deeply human enterprise that fulfills basic human longings, such as for beauty and truth, and when properly engaged, it builds virtues like persistence, creativity, and a competence to solve problems you've never seen before. These virtues will serve you well no matter what you do in life. The deep connection between mathematics and human desires show why people in every culture around the globe do mathematics, not just to build things and conduct commerce, but for enjoyment and exploration. An incarcerated man---now my friend---has helped me see this more clearly than ever before." - Francis Su

Getting To Know the 2023 Mathematics Framework (Asynchronous Course)
Session Information:
This is a 5 module series designed for all educators and math enthusiasts interested in promoting dynamic and inquiry-driven approaches to
teaching mathematics. Participants will explore the Five Components of Equitable Math Instruction which include; Teaching to Big Ideas, Use Open Engaging Tasks, Cultural and Personally Relevance, Invite Student Questions and Conjectures, and Promote Raasoning and Justification. Educators will have opportunities to understand the research, reflect on the implications for their work, and plan for the use of these components in their classrooms and school sites.

Reflection: A Teacher and Student's Math Stories Student Math Stories Pre & Post Sharing Math Stories Builds Community & Belonging Asynchronous Virtual Learning: 2023 CA Mathematics Framework “The aim is to have students come to view mathematics as a subject that is about sense-making and reasoning, to which they can contribute and belong. To achieve this, teachers need to create more opportunities for students to engage in intriguing, deep tasks that honor their ideas and thinking and draw on their backgrounds, interests, and experiences.” Ch.2.Teaching for Equity and Engagement, pg. 45 Administrators, & anyone interested in inclusive education

Robust Discourse IS Math Class: Using the Math Talk Which One Doesn’t Belong to Unearth Brilliance
Organizing for an Equitable and Joyful Mathematics Classroom Series
The Which One Doesn't Belong?/Which One is Unique? Math talk routine engages students in meaningful mathematical discussions and develops their ability to think flexibly and strategically. All choices are correct, which shifts the focus to justification and provides multiple entry points for all learner abilities. It isn’t about guessing the correct answer; it’s about expressing mathematical relationships precisely to build community with others, which elevates the importance of building upon peers’ ideas and valuing their thinking as much as their own. It conveys that math is about sense-making and that all students’ ideas and voices are valued.
