A Math Adventure! Julie Ellis and Phyllis Hornung Peacock team up once again to explore Pythagorean ratios in this humorous sequel to What's Your Angle, Pythagoras? Pythagoras and his cousins want to win a music contest, but first they must figure out how to play their instruments in tune, something that's never been done before. While trying to fix the problem, Pythagoras makes an important discovery--notes that sound pleasant together have a certain mathematical relationship. When Pythagoras applies this ratio to his cousins' pipes and lyres, the result is music to the ears.

Dinner is served. What in nature could be more poetic than the hunt for food and the struggle for survival? In twenty-nine poems readers will squirm at the realities of how the animal world catches food, eats it, and becomes dinner in turn. In these quirky poems readers are introduced to many animals with disgusting eating habits, such as the marabou stork that lurks on the periphery, like a vampire in the shadows, waiting for a chance to pick at a rotting carcass. The dermestid beetle does not mind doing the dirty work, cleaning up animals on the road side and often made busy at museums cleaning up bones for exhibits. And, baby wasps hatch inside an unsuspecting caterpillar and eat their way out. Gross, cool, and extremely funny, David Clark's illustrations get to the heart (and skin and guts) of the food chain and the web of life, depicting the animal world at dinner time in all its gory glory. Back matter includes further information about the animals in the poems and the scientific terms used.
Get ready for an alphabet revolution! X is exasperated. Every other letter in the alphabet has so much to do and plays such important roles in making words. X expects more. He calls for a vote on a new alphabet (gasp!). According to the Alphabet Constitution, X has every right to question the status quo. But the night before the vote, X is plagued by dreams of what could happen if he were to take on another letter's job. S has to run around a lot making singular words plural, except sometimes he isn't needed at all, and sometimes he needs to bring along another letter... it was all very confusing. Then X thought he'd like to be E. E was very important and very useful. E agreed. But E was exhausted. He was in thousands of words and constantly busy. X didn't think E's job was a good idea after all. Jef Czekaj explores the order of the alphabet and the rules of spelling and grammar with hilarious consequences. His graphic-novel-style illustrations make these concepts and the story of X exciting, exhilarating, and extraordinary.
