ab: Summary: This paper reports a study investigating potential uses of Fermi
problems to introduce mathematical modelling to Swedish upper secondary
school students. The work of three groups of students is analysed using
an analytic tool referred to as the “modelling activity diagram",
adapted and developed by the author. It was observed that the processes
involved in a mathematical modelling cycle were richly represented in
groups’ solution. The students also frequently used their personal
extra-mathematical knowledge in the solving process in three different
ways: a creative, a verifying and a social way.
