    Learning first-degree equations represents an important entry point into algebraic thinking. In the classroom, difficulty arises when students remember procedures but do not understand that equality is preserved because both sides retain the same value. This article analyzes the changes recorded after the planned use of the PhET “Equality Explorer” simulator among tenth-grade students at “Gabriela Mistral” Educational Unit. The study followed a quantitative approach with a one-group pre-experimental design and pretest-posttest measurements. The sample consisted of 35 students selected through non-probabilistic convenience sampling. Guided activities focused on identifying the unknown, interpreting the equal sign as a balance relationship, and applying equivalent operations on both sides of an equation. The total scale mean increased from 10/50 in the pretest to 45.34/50 in the posttest; the dimensions of interactive representation of equality and perceived learning reached final means of 22.49/25 and 22.86/25. The posttest scale showed acceptable internal consistency (α= .831), and the Wilcoxon signed-rank test showed significant differences (p < .001). Because the instrument was self-reported, the pretest displayed a floor effect, and no control group was included, the findings are interpreted as perception changes associated with the intervention rather than causal evidence or a direct measure of achievement
