In this paper we report about a small-scale classroom experiment on teaching area measurement with a digital geoboard. The two-lesson teaching sequence that was developed, was tested in two sixth-grade classes and was aimed at teaching students using measurement strategies in a flexible way. The pre- and posttest data were analysed both on task and student level. The results show that most of the students developed more flexible strategies, but many of them did not use them accurately. Our results indicate that apart from working on the ability of students to find correct answers, also the flexible use of strategies can be realized through education.
