Stereometric warm-ups_students
Spatial imagination belongs among the innate abilities of a man. This means that one is born with certain assumptions of spatial imagination. These are needed in everyday life, but especially in the pursuit of various occupations, such as engineering, construction, design, medicine and many others. On the other hand, a number of researches have been conducted to investigate whether the level of human spatial imagination can be developed throughout life. It has been found it can be, but it was also realized that there are so about 3 periods of human development in which the level of spatial imagination can be developed best. If we focus on two of these periods that are in the school age and give appropriate incentives, it is very likely that the level of spatial imagination of the students will increase. For example, the inclusion of stereometric warm-ups in Mathematics lessons may be suitable stimuli. This GeoGebra book in a version for students lists several suitable stereometric warm-ups created in software GeoGebra. The GeoGebra applets of stereometric warm-ups are created in such a way that students can practice their spatial imagination solving them.
