KB Teachers: Great Site for Teaching

In my pursuit of engaging my girls with my attempts at homeschooling, I'm up for websites that will provide educational opportunities and/or fun for my girls.  With fall upon us, I was looking for some activities and found these printables at KB Teachers.

These are going to be great for my four year old.  There are so many resources available ranging from math to science to reading and much more.  I had never heard of KB Teachers until I saw a tweet and cannot wait to make this a routine stop for some additional learning activities.
