Spatial thinking plays a fundamental role throughout the K–12 curriculum. Whether it is the learning of science, mathematics, art, physical education or literacy, spatial thinking skills are important. For example, high school chemistry requires students to understand the spatial structure of molecules. Physical activity calls on students’ awareness of their body’s position in space and with respect to other objects. Art – of all forms – is filled with opportunities to engage our spatial skills, whether it is playfully manipulating shapes and forms while painting or representing musical notes spatially. Of particular importance, however, is the role of spatial thinking in mathematics education. Research findings across education, psychology and neuroscience reveal a close link between spatial thinking and mathematics learning and achievement.
