Introduction (Preliminary research), the prototype stage (development or prototyping) and the assessment phase (assessment phase). The results of the validation assessment by the three validators obtained an average score of 89.9% with a very valid category. the results of the practicality assessment of the e-module conducted by teachers and fourth grade elementary school students obtained an average score of 90.7% in the very practical category.
