18 Months to 3 Years


3 to 6 Year Olds




I AM able to move freely throughout my environment.  I am able to express myself creatively. I am able to do for myself many things because I am given the opportunity to try.

Early Childhood

I CAN use my hands to discover, learn, and create joy.  I can absorb large amounts of information.  I can follow my individual interests. I can learn from and lead my peers.


6 to 10 Year Olds


I WILL question and research things that interest me.  I will use my social interest to develop my sense of justice.  I will learn to persevere.  I will expand my sense of place in our world.
