Students will need lots of pattern blocks to complete this activity.
If you do not have a large number of pattern blocks, you can download a series of pattern blocks sheets (46 KB PDF) and print them onto coloured paper.
Students use their pattern blocks to make
-
regular hexagons
-
irregular hexagons
-
convex irregular hexagons
-
non-convex irregular hexagons.
It is possible to build a hexagon that has equal sides but unequal angles.
You can download the Pattern blocks hexagons: Student worksheet which also has some suggestions for pattern block combinations if students run out of ideas.
