Abstract The educational system in Jordan has developed the curriculum, especially the mathematics curriculum, for all grades. Therefore, the study aimed to analyse the content of the developed mathematics curriculum for the tenth grade according to the levels of thinking based on Bloom’s cognitive taxonomy. The study adopted content analysis as it is the appropriate method to achieve the aim of the study. The study relied on the mathematics curriculum teacher’s guide to refer all cognitive objectives and classify them according to atonement levels based on Bloom’s cognitive classification. The result showed as: 1) The developed mathematics curriculum for the tenth grade includes all levels of mathematical thinking to a varying extent. 2) The geometry standard in the mathematics curriculum developed for the tenth grade has the highest percentage of thinking levels according to Bloom’s cognitive classification. 3) The developed mathematics curriculum for the tenth grade focuses on the level of applied thinking.
