本書嚴格遵循現(xiàn)行小學數(shù)學課程標準精心編纂，巧妙運用引人入勝的故事情節(jié)作為知識載體，將抽象的小學數(shù)學概念與原理生動展現(xiàn)。通過細致入微的知識點講解，結(jié)合精心設(shè)計的動腦思考題與動手實踐環(huán)節(jié)，不僅激發(fā)了學生的學習興趣，更培養(yǎng)了他們的主動探索精神。書中穿插典型例題及其變形題目，輔以深入淺出的解析，鼓勵學生觸類旁通，深化對數(shù)學知識的理解與應(yīng)用能力。此選題特別注重數(shù)學思維的磨礪與拓展，引領(lǐng)學生窺見數(shù)學之美，探索其背后的邏輯與奧秘，為學生拓寬視野、豐富知識底蘊奠定堅實基礎(chǔ)。
蔣守成，江蘇省小學數(shù)學特級教師，江蘇省333工程高層次人才培養(yǎng)對象，常州市特級校長，龍城十佳校長，常州市金壇區(qū)東城實驗小學校長，全國名師工作室聯(lián)盟常務(wù)副理事長，江蘇省小學數(shù)學專業(yè)學會理事，數(shù)學主題拓展教學的創(chuàng)立者，在遼寧海城、新疆克州、寧夏寧東、內(nèi)蒙土默特左旗、陜西石泉等地成立了蔣守成名師工作站。先后主持了6項江蘇省重點資助和規(guī)劃立項課題，其研究成果獲江蘇省教學成果獎一等獎，《中國教育報》《江蘇教育》《學習強國》等進行了研究成果推廣和專題報道，應(yīng)邀到全國28個省、市、自治區(qū)上展示課、做專題報告。先后出版了多部圖書，如《華羅庚實驗學校數(shù)學課本》 《小學數(shù)學奧林匹克同步訓練ABC》《走進你知道嗎》等。
