Authors: Soma Salim S 
Published: November 2019

Abstract
Reasoning-and-proving is believed by mathematics educators worldwide as an essential part of teaching and learning mathematics. In addition, relating a mathematics problem to real-world situation can help student making sense of a mathematics concept. One of the main sources used in Indonesia is mathematics textbook of Kurikulum 2013 which is provided by the government for free. Therefore, this study aims to look at students’ opportunities to solve rela- world related problems that involves reasoning-and-proving activities in the mathematics textbook focusing on the grade 7 textbook, chapter 1 about Number. The methodological approach and analytical framework used is a combination between framework of reasoning-and- proving activities and the use of real-world related problems. The results show that mathematical problems involving reasoning-and-proving activities provided by the textbook are still limited, counting for just around 20% while 80% of the problems cannot be identified as reasoning-and- proving. Slightly higher, real-world related problems in the textbook count for approximately 30% while 70% of them are not related to real-world situations. The results suggest that grade 7 students who use the textbook of Kurikulum 2013 have inadequate opportunities to learn real- world related problems and reasoning-and-proving activities from the book.
