He's also learning about growing up: making friends and finding his own unique talents.\u003c\/p\u003e\u003cp\u003eThe youngest of readers, ages four to six, will love the story of Mark who is not so different from them-which will help prepare them for encountering their world and the world of math. Older readers, ages seven to nine, will thrive on the \"mirror writing\" in the vibrant illustrations-this writing is like a secret language that shows thoughtful messages meant to inspire; the cipher to be deciphered is a cool bonus. All kids will delight in the surprise at the bottom of each page-flip the pages like a flip book and see the adorable little animation come to life. \u003c\/p\u003e\u003cp\u003eEven adults will enjoy the story for its math concepts and humor. For example, readers learn about the order of operations: \"Taking care of what is inside the parentheses first\" is what Mark's parents do. They are each a \"parenthesis,\" surrounding Mark with love. Taking care of him is their first priority. \u003c\/p\u003e\u003cp\u003eMath can be a big unknown factor to many, but by enjoying Mark's adventures, the world of math-and the world in general-won't seem so scary after all.\u003c\/p\u003e","brand":"Worthy Values","offers":[{"title":"Default Title","offer_id":47018620715248,"sku":"9780578168944","price":16.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9780578168944_p0.jpg?v=1763720867","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9780578168944","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
