This study described mathematics teachers' views on the significance of reasonable answers and how they address this concept in their classrooms. Data were gathered from thirteen eighth-grade Kuwaiti mathematics teachers in two middle schools. All teachers in Kuwait use the national textbook and follow the accompanying instructional plans provided by the Ministry of Education. The results revealed that the overwhelming majority of Kuwaiti teachers reported that an answer needed to be exact to be reasonable. Only three teachers reported discussing reasonable answers and their discussions were in response to student mistakes. None of the teachers addressed the concept proactively, considering reasonableness when planning their lessons or preparing activities or exercises. They defended their lack of attention to this concept by noting that the notion of reasonableness is not included in the Kuwaiti national curriculum.
