Abstract: The first part of this article reports the results of a survey focusing on estimation skills relating to the concept of volume. The survey tested pre-service and in-service math teachers of various nationalities and various school types, and investigated their skills in estimating volume ratios of essential solids (a cylinder, a ball, and a cone). The second part of the article analyzes the mathematical background of cone and ball cases. The third part of the article shows the possibilities of GeoGebra software in creating test materials for similar surveys, and --- in accordance with the results of the survey --- presents dynamic models designed to enhance estimation skills in volume ratios. The text gives detailed instruction on how to create such kind of GeoGebra materials.
