You may have heard about the Texas Bluebonnet list; for, many schools in the Houston area include these books as part of their curriculum. On the other hand, library costumers are confused about the 2x2 booklist. I hope to clear up any questions you may have in this post. If you have any additional questions, feel free to write a comment, and I'll be happy to answer it for you.
"The 2X2 Reading List is a project of the Children’s Round Table, a unit of the Texas Library Association. The 2X2 Committee‘s charge is to produce a list of 20 recommended books for children, age two to grade two."
