Unit Studies and Lesson Plans are available in bulk online, but it’s knowing how and where to find them to suit your ‘school’ needs.
A refined www.google.com search helps:
– Use the speech marks and add a common base word to define the topic eg lapbooks. Experiment with a few topic variations. eg. mandela “nelson mandela” anc mandela apartheid mandela
http://homeschooling.about.com/cs/unitstudies/a/unitdirectory.htm – by subject, grade level, A-Z
eg L includes Little House on the Prairie, leafy greens, Lewis+Clark etc
By academic subject:
eg. science, ss/geog, language arts
