The first project meeting took place on July 6th and 7th in Heidelberg. After getting to know each other in person at a dinner together in Heidelberg’s old town, the partners exchanged ideas about their experiences with the digital task format. The upcoming tasks were then specified and processes discussed. The Project and its aims were presented to the Math Education Department of the Heidelberg University of Education. For the supporting program, a trip to the Königstuhl provided a nice setting.
