The aim of the research was to identify (the effect of numbered heads strategy on the achievement of intermediate second-grade students in mathematics and their attitudes towards it); the research sample consisted of (64) intermediate-grade students, distributed into two groups: experimental by (30) students, and control by ( 34) Students. The researcher studied mathematics for students of the experimental group according to the numbered heads strategy, and students of the control group according to the usual method; the researcher  prepared an achievement test consisting of (30) objective paragraphs of the type of "multiple choice", and a measure of the direction towards mathematics consisting of (36) paragraphs There are three alternatives (approved, neutral, disagree) distributed equally across six areas by (6) paragraphs for each field, and their validity and stability have been verified; the two tools were applied to students of the two groups, and the results showed: There is a statistically significant difference at the level of significance (0 , 05) among the mean scores of the experimental group students who N. They studied with the numbered heads strategy and the average score of the control group students who studied in the usual way in the achievement test and the measure of the direction towards mathematics for the benefit of the experimental group students.
