How do I support parents teaching their children math?

Susie, this depends on the context and your role in it. Are the parents your friends, or your employees, or teachers of the kids in the math circle? In general, parents need to tie their math activities to what they already do. For example, parents who read to kids can also read math-rich stories. Parents who play board games can add Nim, Set, or Chocolate Fix. Parents who belong to playgroups can have "math play dates" with their friends. Many parents want help organizing group events, such as Math Circles or Pi Day parties.

You can host question and answer meeting for local parents, and they will tell you what support they want!
