The aim of the study is to deepen the understanding of teacher's perspective on how to promote all children's learning in reading and writing in grade 1 of primary school. Semi-structured interviews were conducted in a Swedish context with 18 primary school teachers, representing a large collective experience from working as teachers in grade 1. The result shows there is a lack of sharing information and experiences, between preschool class and grade 1, concerning reading and writing activities and instructions. The teachers' perspectives on reading and writing instruction can be described as pluralistic, in the sense that each teacher refers to several strategies and approaches to promote learning and development related to reading and writing. The variation of children appears to give meaning to the work of the teachers in the study, though it also is associated with challenges e.g. the experience of being alone and not sufficient to support children's different abilities, experiences and needs. According to teachers in the study, the additional support in schools is more remedial than preventive since the resources are mainly invested in older students.
