In the summer of 2025, 4 teachers from Salinas Union High School District's La Paz Middle School started a grassroots, Computer Science program, with the aim of integrating Computational Thinking Practices and physical computing skills into their already busy curricula, with no prior experience, no CS background, no set curriculum, and very little funding. How did we do it? Why did we do it? Join us for a journey into the rationale for teacher-led CS instruction, the skills developed in both our teachers and our students in the past year, tips for any teachers who would follow in our footsteps, and a bounty of resources, templates, lesson plan ideas and tools developed by teachers, for teachers, already tested in our classrooms, to make your first year journey a little less bumpy than ours!Bui
