Teaching in the dental technical field the best activity that I have used was to make a model of the human teeth and have students paint various restoration on the model's teeth. The painting assisted them in understanding what the various materials should look like in the mouth. The second step to this activity was to then swap models with a fellow classmate and chart the findings of that model. This taught the student how to read a dental chart for the patient that was present in their dental chair without even looking in their mouth. It reinforced the visual information and how to convert it to a chart.
