Biographie:
David E. McAdams er h?fundur, kennari og ?vilangur k?nnu?ur hugmynda. Me? starfsferil sem spannar ?ratugi ? st?r?fr??imenntun og dj?pa ?str??u fyrir ritun hefur David sami? fj?lbreytt ?rval b?ka sem blanda n?mi og ?myndunarafli. Verk hans n? allt fr? skemmtilegum ?rautab?kum fyrir ung b?rn til ?tarlegrar sko?unar ? st?r?fr??ilegum fastast?r?um, lei?arv?sa um or?afor?a og gagnvirkra n?ms?rr??a-allt hanna? til a? opna dyr a? uppg?tvun. Fer? Davids h?fst ? kennslustofunni ?ar sem hann kenndi st?r?fr??i ? framhaldssk?lastigi og uppg?tva?i sannleika sem hefur lei?beint starfi hans ? s??an: B?rn l?ra best ?egar ?au eru virk, forvitin og hafa gaman. Sm?m saman t?k hann eftir alvarlegri gloppu ? st?r?fr??imenntun-nemendur ?ttu ? erfi?leikum ekki a?eins me? hugt?kin heldur l?ka tungum?l st?r?fr??innar sj?lfrar. S? inns?n leiddi til ?ess a? hann skapa?i All Math Words Dictionary, yfirgripsmiki? og barnv?nt ?rr??i til a? efla st?r?fr??i-or?afor?a og b?ta skilning. En David l?t ekki ?ar vi? sitja. Hann h?f a? skrifa b?kur fyrir unga lesendur, innbl?snar af st?r?fr??i-b?kur sem gle?ja um lei? og ??r kenna. ? One Penny, Two spinnst heillandi saga um galdrakennda tv?f?ldun aura. ? What Is Bigger Than Anything? eru b?rn kynnt fyrir hugmyndinni um hi? ?endanlega. B?kurnar My Favorite Fractals og Geometric Nets Project Books hvetja b?rn til a? kanna mynstur, t?lur og r?mfr??i ? ??reifanlegan og gle?ilegan h?tt. B?kur Davids eru oft leikandi, lj??r?nar og innbl?snar af undrum hins raunverulega heims: risae?lum, ?vint?rum, geimnum, mj?kd?rum, feluleik-jafnvel sveiflum ? leikvelli. Hver saga e?a ?raut er sm??u? ekki a?eins til a? kenna heldur til a? kveikja ?myndunarafli?. N?leg verkefni hans fela ? s?r safn af hundru?um st?r?fr??i?rauta fyrir sex ?ra b?rn og ?emara?ir sem blanda st?r?fr??i vi? allt ?a? sem b?rn elska: ?sstruta, fj?rsj??sleitir, galdra og meira til. Verk hans hafa veri? ??dd ? nokkur tungum?l, ?ar ? me?al beng?lsku, og gera ?annig gle?ilega n?lgun hans a? n?mi a?gengilega enn fleiri b?rnum um allan heim. Hvort sem hann telur stj?rnur e?a kannar t?lustafi ? (p?) kemur David fram me? umhyggju og forvitni ? hverri s??u. N?, kominn ? eftirlaun fr? kennslu, n?tur David gar?yrkju og skapandi gle?i ritstarfa. Hann skrifar enn daglega og hugsar st??ugt upp n?jar lei?ir til a? hj?lpa b?rnum a? sj? fegur? st?r?fr??innar, kraft tungum?lsins og t?frana vi? a? spyrja: Hva? ef?...

Sommaire:
David E. McAdams is a storyteller, educator and lifelong explorer of ideas. With a career that spans decades in mathematics education and a deep love for writing, David has authored a wide array of books that blend learning with imagination. His work ranges from playful puzzle collections for young children to detailed explorations of mathematical constants, vocabulary guides and interactive learning resources-all designed to open doors to discovery. David's journey began in the classroom, where he spent time teaching high school math and discovering a truth that would guide his work ever after: children learn best when they're engaged, curious and having fun. Over time, he noticed a critical gap in math education-students were struggling not just with concepts, but with the language of math itself. That insight led him to create All Math Words Dictionary, a comprehensive and kid-friendly resource to strengthen math vocabulary and improve comprehension. But David didn't stop there. He began to write math-inspired books for young readers, books that delight as they teach. In One Penny, Two, a magical penny-doubling story unfolds with charm and wit. In What Is Bigger Than Anything?, children are introduced to the mind-stretching idea of infinity. His My Favorite Fractals and Geometric Nets Project Books invite children to explore patterns, numbers and geometry in tangible, joyful ways. David's books are often playful, poetic and themed with real-world wonder: dinosaurs, fairy tales, space, stuffed animals, hide-and-seek, even swing sets. Each story or puzzle is crafted not only to teach, but to spark imagination. His recent projects include a collection of hundreds of math puzzles for six-year-olds and a themed series that blends math with everything kids love: ice cream cones, treasure hunts, magic tricks and more. His work has been translated into several languages, including Bengali, making his joyful approach to learning accessible to even more children around the world. Whether he's counting stars or exploring the digits of Pi, David brings a deep sense of care and curiosity to every page. Now retired from teaching, David enjoys gardening and the creative joy of writing. He continues to write daily, constantly dreaming up new ways to help children see the beauty of math, the power of language and the magic of asking, What if?...
