Marbles Training session with Dr. Herbert Puchta This special training session for colleagues using Marbles in their classes, and for others who are interested in adopting it for the next school year, Herbert Puchta will take a close look together with you at a sample unit from both, Marbles 1 and 3. He will discuss the key elements of these units, and give a number of practical teaching tips on how to teach them in such a way that students will be engaged cognitively and emotionally, so they learn well and have fun at the same time!  Explore the event
