I have to say there are somethings in life that I will never get tired of seeing. My children taking the lead and delving into topics that interest them would definitely fit this bill.
We are not unschoolers in the traditional sense of the word. We do have a curriculum that we follow and I do make sure they are doing certain lessons each day. I do however let them spend quite a bit of time working on their own projects and interests through out the day in an attempt to encourage self directed learning.
There is nothing sweeter to me than to see children really investigate and learn about a topic that interests them. The fact that they are doing this all on their own makes it even sweeter.
You never really know which way their interests is going to take them on a given day. They may spend one entire day working on airplane collages and learning the name of every single air frame they can find (thank you hubby!). Then the next day they are learning how to build little cottages complete with peaked roofs and decorative accents.
I love watching their little brains work on new projects and follow their investigative instincts to new discoveries. I would have to say it is by far my favorite part of homeschooling!
