This qualitative action research study explores six reading strategies to engage students in more dynamic reading through the implementation of workshops focused on the cross-curricular approach to develop critical reading skills among ninth graders at a public school. The study was conducted with 22 students selected, in the city of Manizales, Colombia. The data collection instruments were students' artifacts, teachers' field notes, focus group questionnaires, survey questionnaires, and documentary analysis. The findings demonstrate that the use of reading strategies within a cross-curricular approach facilitates the development of critical reading in students. In addition, the design of materials (workshops), based on topics related to the students' environment, has an impact that not only contributes to improving their knowledge of English but also to expanding their knowledge in other areas of the academic field.
