I, absolutely, love using the "Kidpreneurs: Young Entrepreneurs with Big Ideas!" book, written by Matt and Adam Toren. The illustrations are colorful and the book is an easy read for students of all ages. I've used the materials in our after-school and summer programs. More importantly, the customer service is impeccable and timely. Thank you, Adam and Matt for your leadership! I am looking forward to the hard copies of your workbooks in the future. ;)
