The current study examined the effectiveness of the educational Lego “More Math” on the mathematical progress, spatial understanding, working memory, and processing speed of students in female first grade of elementary school. female first-grade students. The research employed a quasi-experimental design incorporating a pre-test and post-test framework, with the inclusion of a control group. The population of this study consisted of female first-grade students studying in the schools of Tehran District 14 in the academic year 2022-2023. Among the available schools in District 14, Mihrab Girl’s Elementary School was selected as the sample. Then, 30 students were selected by convenience sampling and randomly assigned to the experimental (15 students) and control (15 students) groups. The data were collected by the Wechsler Intelligence Scale for Children, Fifth Edition (WISC-V), which consisted of ten sub-tests comprising five sub-scales for fluency, language comprehension, visual-spatial reasoning, processing speed, and working memory, and the teacher-made math test. The Lego More to Math educational protocol consisted of weekly training sessions over the course of 15 weeks, with each session lasting for 60 minutes. The data were analyzed using univariate and multivariate analyses of covariance by SPSS26.The analysis revealed significant differences between groups for spatial perception (F = 1.48, p = 0.00, η² = 0.36), working memory (F = 12.13, p = 0.00, η² = 0.32), processing speed (F = 18.16, p = 0.00, η² = 0.42), and math progress (F = 5.78, p = 0.00, η² = 0.29, test power = 0.9), with non-significant pre-test results (p = 0.88) and significant group differences (F = 11.36, p = 0.00). The study demonstrated that the Lego "More to Math" educational program significantly enhanced first graders' mathematical progress, spatial understanding, working memory, and processing speed. These findings suggested that incorporating structured, play-based learning tools like Lego into early education effectively boosted cognitive and mathematical skills in young students
