"What was most challenging about this activity? Was it easy to make a proper tessellation?"
It was not easy to make tessellations with the pattern blocks! It was most challenging to make the same exact patter go up, down, side, side no gaps or overlaps so it was tricky not to add any pattern blocks that wouldn't fit in the tessellation.
