Do your kiddos enjoy reading mystery books? If so, then they will love the Boxcar Children series! I loved reading it as a child, and my children have really enjoyed it as well. In case you want to add it to your studies, I found this GREAT Boxcar Children Unit Study from Frugal Homeschooling Mom  to go along with it.
You’ll find field trip ideas, video links, author information, printables, and more to go with The Boxcar Children! Don’t miss all the Free Homeschool Language Arts resources  on How To Homeschool for Free !
