Query: A must-read for every parent and teacher.

This book has everything you can possibly imagine for the 3rd Grade student. It is especially a must for the home school parent. I no longer wonder if my children are learning what they should, I know as long as I use this and the other series of Core Knowledge books, they are getting the education they should. Also, read the "What your ________Needs To Know: Fundamentals of a Good _____ Grade Education" for grades Kindergarten through 6th grade, all E.J. Hirsch, Jr. books.
