Tips for Supporting Your Children's Learning

Get your child actively involved in their own learning and having their questions drive the learning. Let them observe and figure out, and try to hold back from answering questions for them. Instead, try to ask: What do we know? What else can we find out? How might we figure that out? Don't be afraid to ask your child questions.  Also, don't be afraid to say "I don't know--let's find out together!" as a way to respond to their questions.  Here's an article to help you support this kind of learning:  Of the Value of Saying I Don’t Know
