This article aims to report on a pilot or proof of concept study with experienced Hungarian teachers who introduced mathematical concepts through a sequence of lessons utilising a pedagogical framework (Lavicza, Hohenwarter, Jones, Lu and Dawes, 2009a and Lavicza, Hohenwarter and Lu 2009b) for general technology integration. Our aim was to examine whether the results of this pilot study could be further utilised in material development and teachers training in a larger scale project GEOMATECH. Results of this study suggested that: a) even experienced teachers with extensive knowledge of technology use are challenged to transfer the control of the classroom to students, step back to become a facilitator in the classroom; b) teachers would have required already prepared worksheets that could be immediately suited to their lessons as their time for preparation was limited and needed to cover a wide range of materials; c) introducing technology through such sequencing would require more practice, experience and training.
