The study investigated the level of including mathematical proficiency skills in the sixth grade mathematics textbook and acquiring grade's students for these skills. To achieve that, the descriptive approach (survey and content analysis) was used through two prepared instruments: A content analysis card for identifying inclusion level of mathematical proficiency skills (conceptual understanding, procedural fluency, strategic competence, and adaptive reasoning) in the sixth grade mathematics textbook and a test for identifying acquisition level of a sample of (518) sixth grade students at the elementary public education in Jazan Educational Governorate, Saudi Arabia. The study took place during the second term of 2020-1441AH. The results showed that the inclusion level of mathematical proficiency skills in the sixth grade mathematics textbook was low for the conceptual understanding skill, and medium for the procedural fluency, strategic competence, and adaptive reasoning skills, and the level of students' acquisition of these skills was lower than the educationally acceptable level (75%). In light of the results, a number of recommendations was presented. (Published abstract)
