Current Event #8 - Teacher-Created Math Textbooks

For the second week in a row, my husband has led me to my weekly current event.  This week it was a link on his facebook page for a parenting blog about math teachers in a Minnesota School District who created their own online math textbook for a fraction of their textbook budget.  The book is relevant to their students, a living document that can be changed or updated, and prints at about $5 a copy after the initial $25,000 to cover the teacher wages and initial start-up costs.  The teachers used a free online framework from the CK-12 Foundation to create the textbook.
