ab: Summary: We describe a classroom experience based on the sequencing of
Fermi problems related to estimating large quantities. The models used
by a group of Compulsory Secondary Education (16 year-old) students are
described herein. The variations the students apply to the models in
order to adapt them to similar problems formulated in different
contexts are shown. In the conclusions section, we reflect on this
didactic proposal and the possibilities it offers to the students, so
that they assimilate and internalize the models worked on.
