A research aimed to measure of effectiveness of the blending of the strategy of the ideas gardens and the visual approach in the development of some of the knowledge economy skills in mathematics for the students of the second prep stage. The present research used experimental design based on the system two groups of students of the second prep stage at a school governorate Qalyoubiya by classroom for each group, one experimental group studied the content of the two units of the relationship between two variables and the statistics by blending of the strategy of the ideas gardens and the visual approach and number of(50)schoolgirls, and other control studied the same content of the two units by being traditionally in schools, and number of (47) schoolgirls, for a total sample (97) schoolgirls. The present search bore out the following results: 1) There is a statistically significant difference between scores mean of the students in the experimental group and the control group concerning the posttest of the knowledge economy skills (total score and individual skill) in favor of the experimental group. 2) There is a statistically significant difference between the mean scores of the experimental group on pretesting and post testing on the knowledge economy skills (total score and individual skill) in favor of post testing mean scores. 3) There is effectiveness of the blending of the strategy of the idea’s gardens and the visual approach in the development of some of the knowledge economy skills in mathematics (total score and individual skill) for the students of the experimental group.
