In this paper, we study the external didactical transposition of programming and computational thinking (PCT) into the Danish compulsory school mathematics curriculum. Taking an anthropological theory of the didactic approach, we focus on the nature of mathematical and PCT knowledge being transposed into the new curriculum as prescribed praxeologies. Two main critiques arise. First, PCT knowledge being transposed into mathematics is broad and has no immediate relation to definitions from the literature. Second, the new competence and subject-matter areas are barely juxtaposed to those from mathematics. As a consequence, the responsibility of developing meaningful integrations in concrete teaching—the internal didactic transposition—lies entirely on teachers and material developers.
