ab: Summary: This study was conducted to investigate the possibility of
teaching tessellations’ mathematical principles in elementary school
mathematics. A survey was carried out and the two hours of the
instructional experiment were developed for this study: triangular
tessellation activity and rectangular tessellation activity. Six fifth
graders from W elementary school participated voluntarily in the
instructional experiment. It was shown from the survey that teachers
and students both know what the tessellation is, but they don’t know
what the mathematical principles really are in the tessellation. This
is because they have just done the covering up-activities in class. It
was seen from the instructional experiments that even ordinary students
were able to understand the mathematical principles of the tessellation
if teachers could throw the suitable focusing questions like “how to
move the rectangles making sides equal” and “how to gather vertexes
making angle 360$^\circ$. Furthermore, it is desirable to teach the
rectangular tessellation prior to the triangular tessellation since the
rectangular tessellation is more easy to deal with than the triangular
tessellation.
