Reading Level (RL3). Perfect Chapter book for Early Readers and those who like a little adventure. Take a Trip to the Black Lagoon. "Brush your teeth with shoe polish. Then survive a ride with Mr. Fenderbender, the scary bus driver. Afterward, swat mosquitoes as large as Count Dracula. All that happens and more, but only in THE CLASS TRIP FROM THE BLACK LAGOON! My 1sr grader loved this book because it was a break from regular chapter books...full of fun illustrations.
