Using Tessellation Pattern Blocks To Explore Equivalent and Congruent Figures

It seems everyone is drawn to Tessellation Pattern Blocks. Anyone who sees the little shapes just can’t help but want to reach out and arrange them. But, besides tessellating and pattern sheets, these shapes can also be used to study equivalency and congruency.

Start by building a shape. This exercise can start very simply – for instance, the first shape can consist of one rectangle.

Then build a congruent shape by placing a second level of blocks directly on top – making sure the figure is completely covered without overhang.

Remove the second level blocks to form a new shape next to the first one. These shapes are equivalent.

Multiple iterations of the same shape will yield a variety of equivalent figures.


As the child gains understanding, quite complex figures can be formed.
