The study used mixed-method research employing sequential exploratory strategy. It collected and analyzed qualitative and quantitative data in the development and validation of the worktext. It was carried out in a two-phase manner. Phase 1 was the development of the material, and phase two was the validation process. The validated module was tested to grade 8 students in a public high school in the Division of Pampanga, and the results revealed that the activities present on the worktext are varied.
