I got a fun note from a friend yesterday, who has been playing with 21st Century Pattern Blocks with his 3.5 year old daughter. He had an idea for 21st Century Pattern Block play that’s worth sharing!

I’m loving these pattern blocks!!! I made a different design like this earlier today, with the 180 degree symmetry, and whenever [my daughter] added a block I would add its partner; we had a pretty good game going for 10 mins or so
