In this article, a collaborative Deleuze-Guattarian-inspired cartography is produced with preschool practitioners to explore the assemblages of teaching in preschool. The aim is to map how teaching comes into being in preschool planning and reflection practices following the movements of territorialisation and re-/de-territorialisation. Unwinding from a policy change that 4 years ago introduced teaching to the Swedish preschool curriculum, the overarching question of what teaching is and could be to follows through the text. The preschool teaching assemblages are visited through three territories in which different continuums of (un)teaching unfold when staying with the emerging messiness. The movements of de-territorialisation open for divergent thinking, questioning traditions and assumptions of how to conduct teaching in preschool practice, in entanglement with both local and global movements.
