大班數(shù)學活動設計：趣味接龍課件教案
重點：了解接龍游戲的規(guī)律，并能運用比較、對應的經(jīng)驗合作制作接龍卡。難點：1.孩子對前后卡片的界限區(qū)分。成因是接龍卡本身有兩小部分所組成，容易會造成孩子辨別卡片上的混淆。2.操作中的前后推理。成因是由于幼兒的逆向思維發(fā)展尚不成熟，容易被附近一個已知數(shù)所誤導。解決策略：1.逐步化解法：借助雙色的卡片做教具，以層層遞進的方式從順向推理向逆向推理逐步過渡。2．資源共享法：以小組合作形式開展操作活動，能以兵兵互教的形式化解補缺的難點，達到資源共享。活動目標：1.了解接龍游戲的規(guī)律，并能運用比較、對應的經(jīng)驗合作制作接龍卡。 2.嘗試用簡潔語言介紹和交流自己的操作結果，能運用以往的數(shù)學經(jīng)驗表明意思。
