Ohio’s Math Teachers’ Circle Network


Find a Math Teachers’ Circle near you. 

​Math Teachers’ Circles are groups of teachers that gather periodically to work together on fun and interesting mathematics. The problems are “low floor,” meaning everyone can get started on them, but “high ceiling,” meaning that the amount of fun to be had in them is endless.
