The latest issue of Teachers College Record includes a book review of “Algebra in the Early Grades”. This important book was edited by late James J. Kaput together with David W. Carraher and Maria L. Blanton, and it was published by Lawrence Erlbaum Associates in 2007. David Slavit provides a thorough review, which gives a nice insight into the main parts of the book.

If you are interested, you might want to check out the information about the book in Google Books (which includes links to where you can buy the book), and you might also be interested in taking a look at this page about Early Algebra.
