I can describe reflection symmetry and rotation symmetry. 
I can describe the symmetry modelled in a
tessellation.  
I can investigate tessellations found in First Nations and Metis star blankets, objects, art, or architecture.
(Grade 6 Math)
This week, we learned that a tessellation is a pattern made of one or more shapes that fit together with no gaps or overlaps. At any point where the shapes in a tessellation meet, the total angle measure is 360°. 
This Cree Starblanket design is an example of a tessellation. It also shows both rotational symmetry and reflection symmetry.  The star has eight points symbolizing kindness, humility, honesty, respect, healing, forgiveness, wisdom, and love. The points face outward which represents the relationship with family, friends, and the community.
We used pattern blocks to make tessellating designs then moved on to a creative art piece 
using tessellations.
We also learned about rotational symmetry and reflective symmetry. The students were able to make connections between this new learning and their previous learning of reflections and rotations on the cartesian plane. We practiced creating and identifying symmetry using pattern blocks, geo-boards, and loose parts. 
A figure has reflection symmetry if it can be reflected across a line and look exactly the same as it did before the reflection.

A figure has rotational symmetry when it can be rotated (less than 360∘) and still look like it did before the rotation. The centre of rotation is the point a figure is rotated around such that the rotational symmetry holds.
