Description
Summary:Mathematics teacher must have a good basic mathematics comprehension such as number sense and spatial reasoning before teach it to the students. Those ability will help a person to solve mathematical problems effectively. The aim of this study is to describe how number sense and spatial reasoning was used to solve mathematical problems. This research is a qualitative-descriptive research with 27 of second year pre-service mathematics teachers as a participant. Subject were selected using purposive sampling by conducting number sense ability test. The one with good number senses abilities were given advanced test related to spatial reasoning. The result of this research shows that pre-service mathematics teacher with good number sense ability can solve the given problems correctly. Subjects can flexibly conduct mental calculation, mathematical computation, and create various number representation accurately and are able to create efficient problem-solving strategy by combining mental rotation and spatial visualization within the process.
