Abstract
We show that the middle school second-generation textbook of mathematics, for the first middle school year, is not committed to the new curriculum, at least from the point of view of the acquisition of competencies in problem solving. We present the structure of the textbook, and we study the resolved problems and the proposed problems and exercises to see the solving strategies that could emerge when solving these tasks. Finally, we conclude. Keywords: Curriculum, textbook, problem-solving, heuristics.
