This memo includes results of data collection from the second cohort of Collaborative Partnership to Teach Mathematical Reasoning Through Computer Programming (CPR2) teachers from classroom implementation of CPR2 in fall 2021. Findings are included for the student pre-assessment, Student Computer Science Attitude Survey, and Learning Mathematics for Teaching (LMT) teacher pre-assessment. Overall, fall 2021 teachers were able to implement the CPR2 activities, and students had opportunities to program. However, little support was given to students for exploring mathematical concepts in depth or generating and discussing mathematical conjectures. Teachers adhered closely to the materials they received and most discussion was dominated by teachers' questions and reasoning. Data collection plans for the CPR2 spring 2022 semester and appendices with assessment and survey instruments are included.
