Theteaching materials used by the teacher in the learning process only use the theme book with thelecture method which occasionally also refers to the KTSP material. Students have difficultyunderstanding the lesson because they are not in direct proximity to the student environment. Thereis no teacher who has developed student worksheets that are interesting in thematic learning fortheme 1 sub-theme 2. One of the efforts that can be made to improve this learning is by developingstudent worksheets. In order to achieve the learning objectives in thematic learning in class IVtheme 1 sub-theme 2, it is necessary to have an educator who has skills in developing a product thatcan be used by students in learning in the form of student worksheets.
