Thematic learning is basically a combination of various disciplines that are covered in natural sciences, so thematic learning requires a more complete textbook and comprehensive compared to non thematic learning (Fitriani, Djamas, & Fauzi, 2019). In one learning topic, a number of learning resources are needed in accordance with the number of competency standards which are the number of study fields included in it. Based on the teaching experience in the lower class and the results of observations at SD N 02 Koto Tuo in Harau Subdistrict, Lima Puluh Kota, in class III, data was obtained that the learning had not fully used integrated thematic learning, the learning carried out by teachers was still expository, namely teachers lecturing and stuffing students with material verbally symbols, another problem found is the use of learning textbooks that are still separate based on subjects. Integrated thematic textbooks are still difficult to find in the field for the 2006 curriculum, although they are available, but they are not in accordance with the learning objectives (Risda Amini, 2017; Gupta & Belford, 2019).
