If you actually crave an organized classroom and your district uses the Reading Street series (2008), these dividers might be just what you need. This product contains a tabbed divider for each of the "Day 4" books (levelized library) contained in the kindergarten series. The dividers are slightly taller than the books themselves, so each title is easily seen. Each one displays the title and number (1.1, 2.3, etc...) of each book. It is color-coded as well (green/intensive, yellow/on level, and blue/advanced). These labels feature the skill to be taught and the vocabulary words that are introduced in the book.
Your days of flipping through a hundred books are now over!
This product is specific to kindergarten.
The first grade version is in my store as well.
