Fall is such a great time of the year.   But it is not all about trees and leaves and halloween.   There is another concept that I think would make a great unit and that is Farm life.  This is great because it pulls in harvest time, pumpkins, corn and more.    I highly suggest you find a local farm to visit.

http://www.parentled.com/   offers a very nice unit for fall called Fall on the Farm. This would be so fun to use along with a field trip to a local petting farm. The unit offers  very nice looking printable abc cards with fall and farm words, pages with lovely pictures that represent fall colors, some great pictures with different type of vowels introduced.  Then they give you a blank page to draw your own pictures and words, several pages where you can either copy the fall on the farm qoutes they offer, or write your own story.  There are some wonderful recipes and blank card to put your own recipes.  Then directions to make all of it into a great lapbook.  
You won't have to search the internet for pictures, they are all provided.  This unit is really worth it.  You can get it at http://sites.google.com/site/parentledhome/  for $3.

Remember all the fall units at http://www.hshighlights.com/   and see our halloween sale right now.   Spend the rest of the month studying Fall on the farm, Halloween, Pumpkins and more.
