BLOCKHEAD

THE LIFE OF FIBONACCI

"You can call me Blockhead, everyone else does." So Leonardo Fibonacci declares in first-person voice in the opening of this picture-book biography. Who was he? Fascinated with numbers as a child, Leonardo grew from a daydreaming boy in medieval Italy to become one of the greatest European mathematicians of the Middle Ages. He found something to count everywhere, but his father wanted him to be a merchant and took him to North Africa to do his accounts. Leonardo learned fractions from the Egyptians, geometry in Greece and Hindu-Arabic numerals from India. He wrote a book that posed his mystifying, multiplying rabbit question. The lively text includes touches of humor; Emperor Frederick called him "one smart cookie." O'Brien's signature illustrations textured with thin lines re-create a medieval setting. The last page lists things to find in the pictures, like a three-leafed clover and spirals, as well as activities that reinforce his concepts. Few people will know this man's name, but the book will be a boon to math teachers, homeschoolers and others piqued by the title. (Picture book/biography. 6-10)

A good overview of this complex, essential organ, with an energetic seasoning of silliness.

THE BRAIN IS KIND OF A BIG DEAL

An introduction to the lead guitar and vocalist for the Brainiacs—the human brain.

The brain (familiar to readers of Seluk’s “The Awkward Yeti” webcomic, which spun off the adult title Heart and Brain, 2015) looks like a dodgeball with arms and legs—pinkish, sturdy, and roundish, with a pair of square-framed spectacles bestowing an air of importance and hipness. Other organs of the body—tongue, lungs, stomach, muscle, and heart—are featured as members of the brain’s rock band (the verso of the dust jacket is a poster of the band). Seluk’s breezy, conversational prose and brightly colored, boldly outlined cartoon illustrations deliver basic information. The brain’s role in keeping the heart beating and other automatic functions, directing body movements, interpreting sights and sounds, remembering smells and tastes, and regulating sleep and hunger are all explained, prose augmented by dialogue balloons and information sidebars. Seluk points out, importantly, that feelings originate in the brain: “You can control how you react…but your feelings happen no matter what.” The parodied album covers on the front endpapers (including the Beatles, Pink Floyd, Green Day, Run DMC, Queen, Nirvana) will amuse parents—or at least grandparents—and the rear endpapers serve up band members’ clever social media and texting screenshots. Backmatter includes a glossary and further brain trivia but no resources or bibliography.

A good overview of this complex, essential organ, with an energetic seasoning of silliness. (Informational picture book. 6-8)

A winning heads up for younger readers just becoming aware of the wider natural world.

DON'T LET THEM DISAPPEAR

An appeal to share concern for 12 familiar but threatened, endangered, or critically endangered animal species.

The subjects of Marino’s intimate, close-up portraits—fairly naturalistically rendered, though most are also smiling, glancing up at viewers through human eyes, and posed at rest with a cute youngling on lap or flank—steal the show. Still, Clinton’s accompanying tally of facts about each one’s habitat and daily routines, to which the title serves as an ongoing refrain, adds refreshingly unsentimental notes: “A single giraffe kick can kill a lion!”; “[S]hivers of whale sharks can sense a drop of blood if it’s in the water nearby, though they eat mainly plankton.” Along with tucking in collective nouns for each animal (some not likely to be found in major, or any, dictionaries: an “embarrassment” of giant pandas?), the author systematically cites geographical range, endangered status, and assumed reasons for that status, such as pollution, poaching, or environmental change. She also explains the specific meaning of “endangered” and some of its causes before closing with a set of doable activities (all uncontroversial aside from the suggestion to support and visit zoos) and a list of international animal days to celebrate.

A winning heads up for younger readers just becoming aware of the wider natural world. (Informational picture book. 6-8)
