本書以童話、小故事、生活中的事件、新聞要點(diǎn)、熱點(diǎn)問題、古詩文、《九章算術(shù)》、《幾何原本》、科學(xué)幻想、科學(xué)現(xiàn)象等內(nèi)容為主，并輔以閱讀提示、閱讀指導(dǎo)和解答問題。著重培養(yǎng)學(xué)生"發(fā)現(xiàn)問題、提出問題、分析問題和解決問題”能力的要求，以提高學(xué)生數(shù)學(xué)學(xué)科的素養(yǎng)。本書兼顧所含年級(jí)及相對(duì)應(yīng)的知識(shí)，篇幅相對(duì)平均，服務(wù)于不同學(xué)生的思維水平。本書成為小學(xué)生課外閱讀的小伙伴，在閱讀每篇小短文的過程中享受學(xué)習(xí)和研究的興趣，在解決問題的過程中獲得知識(shí)和方法的積累。讓不同認(rèn)知的學(xué)生都有收獲。家長(zhǎng)對(duì)孩子進(jìn)行課外輔導(dǎo)，往往憑借自己的學(xué)習(xí)經(jīng)驗(yàn)，缺少專業(yè)性的指導(dǎo)。此書為家長(zhǎng)提供指導(dǎo)學(xué)生閱讀的資料及指導(dǎo)方法。讓家長(zhǎng)和孩子在閱讀中共同體會(huì)學(xué)習(xí)的樂趣�，F(xiàn)行教材分為數(shù)與代數(shù)、圖形與幾何、統(tǒng)計(jì)與概率和綜合與實(shí)踐四個(gè)領(lǐng)域，小學(xué)數(shù)學(xué)知識(shí)處于各個(gè)板塊內(nèi)，跨板塊知識(shí)之間關(guān)聯(lián)內(nèi)容比較少，在教學(xué)中教師也需要具有綜合性的素材。
