We love the unit studies from Amanda Bennett. Last year we did her garden unit study and right now we are working our way through the digital photography. This new series is not a unit study. The Heroes of Today series is actually stories that Amanda rewrote in today's English from older living books. I was thrilled to see these because we do most of our learning from reading and discussing. I purchased the Heroes of American History, America and Inventions to use next year. Go to www.unitstudy.com for special prices until 3/13/12. Normally each unit sells for $10.95 but the special is for $7.00. If you would like to buy the entire set the special is $30.00.
