This study explores how two instructional coaches enacted modeling and co-teaching cycles with five elementary teachers during mathematics instruction. A content analysis of the coachteacher talk from 11 planning meetings and 23 lessons reveals that the coaches and teachers seldom engaged in mathematical conversations. Instead, they primarily had low-depth discussions about curriculum, other instructional materials, and assessment. Implications for school districts with instructional coaching models are discussed.
