This study to identify the inclusion of extent the content of the developed Mathematics textbook for the Ninth Grade in Jordan of standards NCTM. The study population and sample consisted of the content of the mathematics textbook developed for the ninth grade, which was studied starting from the academic year 2022-2023, To achieve the objective of the study, The researcher used the analytical descriptive approach using the content analysis card, A list of standards was determined based on the NCTM2000 standards, The analysis instrument included (55) sub-indicators distributed into five main standards, It was verified for validity and reliability. The results showed that the inclusion of extent the Content of the Developed Mathematics Textbook for the Ninth Grade in Jordan of Standards NCTM in varying percentages: 1) The highest of which was the ”Algebra” criterion, which came in first place with a percentage of (25.68%), 2) In second place the ”Engineering” standard with a percentage of (23.12%), 3) In third place the ”Data Analysis and Probabilities ”standard with a percentage of (22.43%), 4) In fourth place the ”Numbers and Operations” standard with a percentage of (19.35%), 5) Finally came the standard. ”Measurement” with a percentage of (9.42%). The study recommended that the mathematics textbook for the Ninth Grade should include the subject of coordinate geometry with regard to the use of Cartesian coordinates. (Author’s abstract)
