The students used geometry grids and Geogebra to identify and reproduce the geometry patterns of the mosaic depicted in the picture. It comes from the Archaeological Museum of San Lorenzo in Cremona, Italy. The students reproduced the pattern choosing the right grid form the ones in the page 'Geometric constructions and patterns', drew it by hand and then constructed it on Geogebra.

       

We construct the geometric pattern by using the follow underlying grid:

by hand:

and Geogebra:
