AU - المعثم، خالد بن عبد الله بن صالح AB - The present study aims to reveal the level of alignment of the mathematics curricula content in the Kingdom of Saudi Arabia with the national mathematics standards for grades (1- 12). A descriptive content analysis method was used. and 11 content analysis cards of the mathematics textbooks for each the grades (1-12). The results showed that the degree of alignment of the mathematics curricula content with the national standards at different levels for grades (1-12) is generally average. with an arithmetic mean of (x̅= 2.17). The Expansion Level was the most aligned level. whose standards were highly achieved. with an arithmetic mean of (x̅= 2.28). followed by the Focus Level. whose standards were achieved at a medium level. with an arithmetic mean of (x̅= 2.245). next by the Reinforcement Level whose standards were achieved at a medium level. with an arithmetic mean of (x̅= 2.10). and finally, by the Foundation Level which was the least aligned level whose standards were achieved at a medium level. with an arithmetic mean of (x̅= 2.07). The results showed that. of all branches of mathematics. “Measurement & Geometry” was the most aligned branch whose standards were highly achieved. with an arithmetic mean of (x̅= 2.30). followed by “Algebra & Analysis” whose standards were achieved at a medium level. with an arithmetic mean of (x̅= 2.19). next by “Probability & Statistics” whose standards were achieved at a medium level. (x̅= 2.17). and finally by “Number & Operations” which was the least aligned branch. with an arithmetic mean of (x̅= 2.07).
