Abstract
A classroom mathematical exploration
of the mean
In this article, we outline a series of explorations
with data, spanning between 3
and 5 lessons, to develop conceptual understanding
of the mean. These explorations
were field tested with 5th class
children in Limerick city schools.
While various real contexts could be
used, this article focuses on an activity
which examines the accuracy of
the assertion that a person’s foot is
the same length as their forearm.
