Synopsis: The aim of this workshop is to bring out two themes: (i) how
critical thinking can be encouraged in elementary mathematics; and (ii) how the
history of mathematics can inspire critical thinking. To do this, I will
consider the example of fractions and decimals. At the upper primary and lower
secondary levels, students are taught to convert fractions to decimals and vice
versa. To many students, fractions and decimals are just two representations of
the same numbers and it is not clear to them why you need two different
representations. I would like to address this. In particular, I will discuss
why fractions and decimals are different and also the advantages and
deficiencies of each. I will refer to ways in which these deficiencies were
dealt with in the history of mathematics.
This is intended to be a 3-hr workshop for upper primary/lower secondary
teachers.
Refreshments will be served after the workshop..
