The reports document difficulties PTs have with decimal tasks,
including comparing and ordering decimals as well as representing decimals (Thipkong &
Davis, 1991), and suggest that the origin of such difficulties stems from the ways in which
PTs interpret decimal notation. Authors identified PTs’ misconceptions and hypothesized
about the origins of these misconceptions. For example, Putt (1995) asked PTs to order a
collection of decimals between zero and one (0.606, 0.0666, 0.6, 0.66 and 0.060). In studies
of children’s approaches to decimals, ordering decimals had been shown to be more
