Practicing Kindness In Kindergarten

Some of the important work that the children do in Kindergarten is practice being a good person; showing kindness, being patient and giving yourself and your friends time to learn.  
When we talk about classroom rules we always revisit the two top important rules -- being safe and being kind.
