Tessellations are geometric patterns that perfectly fill an area with no overlaps. I remember making them using a computer program back in middle school, and marveling at the way the patterns could rotate or connect. Here is a highly simplified version that even a kindergartner can grasp, which can gently introduce your child to the concept.
To make your tessellation, draw a line along one edge of a post-it with marker, in any shape, as long as the line extends from corner to corner.
I had to help Travis a bit with this slightly odd instruction.
Cut out along the marker line, then tape that piece onto the front of the post-it. Your tessellation is ready to go!
Now trace this in a line across a piece of paper.
Once you’ve filled in the paper, color each portion, ideally in a pattern.
Travis did great careful work to color within the lines, and thought the final result looked a bit like the scoots on a turtle shell!
