Young Pythagoras can't seem to stay out of trouble. Every time he tries to help, people get angry. What's a curious kid to do? On a trip to Egypt, Pythagoras' curiosity helps him discover the secret of the right triangle. A clever introduction to the Pythagorean Theorem.
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. This book is good for your brain because: Mathematical problem solving, Ratios, Measuring, Musical Theory, History of Instruments
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.
