When Arnold and Koesha try to organize Arnold's rock collection, they are unable to agree on the best way to sort the rocks, until Liz comes up with a rock-solid solution that makes everyone proud. Original.
This is a fun book about sorting rocks based on different criteria, such as size, color, shape and texture. It stars a few of the primary characters from The Magic School Bus series and is more oriented for younger children and early readers.
This book is about Arnold's rock collection that had Liz in it. And I have one question. Tell me different ways you can sort rocks. Colour. That's it. Texture? You bet. Size. You're grown big as a rock. Shape? Rock-antastic!
My favourite part was the last way they sorted it out. Which was? Guess. A pile? You got it.
