The 2013 curriculum suggests that learning must be integrated or commonly known as integrated thematic learning. Thematic learning in elementary schools usually combines material on several subjects into one theme. The references used by both teachers and students are provided by the government, namely teachers’ book and students’ book. The teachers directly teach their students using references provided without analyzing or further developing by the teacher. The implementation of 2013 curriculum requires teachers to be creative in using various learning models and scientific approaches. With these demands the teacher should be able to develop teaching materials in accordance with the learning model. This research is motivated by the importance of developing integrated thematic teaching materials based on Problem Based Learning models that are able to improve the critical thinking skills of fifth grade students.
