I wanted to share more on the subject of strewing and thought my older posts "Schooling in every room of the house" would fit in well with this topic.  Here is the first post in the series:
Schooling in every room of the house Part 1: the BATHROOM!
As homeschoolers we are famous for using every nook and cranny in our homes to our advantage in schooling our kids.  I love to learn in unexpected or overlooked places.  I am going to start this series of blog entries with ideas for learning in the most overlooked room in the house:  the bathroom
I think the bathroom is one of the BEST places to sneak in learning! It is a room that my boys seem to spend lots of time in - especially when I tell them it is time to clean their room (you all know what I mean!).
Here are some of the ways I squeeze learning into the bathrooms:
1.)  I put a small basket on the floor and a file organizer on the back of the toilet and stuff them with books that my boys don't realize are "educational" (like When is a Pig a Hog?, 5 Minute Mysteries, Big Book of Questions and Answers, More Than Meets the Eye, Brain Surgery for Beginners, Art Fraud Detective, the Murderous Maths  books, Kids Discover magazines, etc.)  Mostly things that they normally would not just pick up to read.  I can't tell you how many times they have come to me after a visit to that room and say "Hey, guess what, listen to this!".  I try to put books in there in the subject areas that I feel we need to spend extra time on such as science, logic, art, or language.
I switch the books out every once in a while and sneak in ones that pertain to what we are learning. 
Here is a picture of one of the file organizers in my bathroom:

2.)  I also use the walls on the bathroom to hang posters, charts, and things I want them to memorize.  Here are some examples:
- When we were studying Shakespeare I plastered the bathroom (yes, the one our guests use) with Shakespeare quotes.  They were sayings that we use every day and never realize we are quoting Shakespeare such as "Eaten out of house and home" - my life story!
- When we are studying an artist I tape their work up on the bathroom wall to be admired while "lounging".  Sometimes I use those cheap Dover $1.00 art postcard packs - while studying Picasso I taped his famous painting post cards up on the bathroom wall in chronological order.
- I have a chart of the books of the bible hanging in there for us to work on memorizing.
- I hang pictures of the solar system, skeletons, the alphabet in sign language - anything!  The possibilities are endless.
So, when you get time, go look in your bathroom and see it with fresh eyes.  You can learn a lot in there!
