The purpose of this study is to find out, through observations and focus group interviews, how four different groups in grade four work with and reason about problem solving in mathematics based on George Polyas problem solving model.

Questions that are as follows: How do the problem solving activities go in the groups? How do the pupils reason about their problem solving activities? We based our selection from different schools.

The results of this study give an insight into better understanding of how pupils work with mathematical problems and how they reason about their problem solving activities. The result also indicates that there is a connection between the pupils problem solving approach and previous research ant theories found in this study.
