(1)讀題,分析已知條件和問題. (2)想想用什么方法算?為什么用減法算?(因?yàn)橐篁哐延卸嗌僦唬仨殢囊还灿?4只里去掉蝴蝶的只數(shù),所以用減法.) (3)列式解答。 2.有蝴蝶8只,蜻蜒16只,蜻蜒比蝴蝶多幾只? (1)讀題,分析已知條件和問題. (2)想想用什么方法解答,為什么用減法算? 提問;這道題還可以怎樣提問題?(蝴蝶比蜻蜒少幾只?) 為什么也用減法計(jì)算? 3.你還能提怎樣的問題呢? 根據(jù)學(xué)生編的加法應(yīng)用題,分析列式解答,并強(qiáng)調(diào)為什么用加法來解答。 四、課堂練習(xí)。 1、口算題. 退位減法表里隨機(jī)抽指. 2.口算 12-8 14-6 12-3 16-9 13-6 11-9 12-4 13-9 14-8 14-5 14-7 11-8 15-6 1l-7 12-7 16-8 13-5 1l-3 18-9 13-8 3.比大?。? 15—7○12—4 16—9○13—8- 1.請(qǐng)仔細(xì)閱讀文檔,確保文檔完整性,對(duì)于不預(yù)覽、不比對(duì)內(nèi)容而直接下載帶來的問題本站不予受理。
