《營養(yǎng)配餐》教學設計

1、營養(yǎng)配餐教學設計教學內(nèi)容：六年級北師大版教材p46至p47。教學目標：1.經(jīng)歷利用數(shù)學知識進行營養(yǎng)配餐的過程，了解有關營養(yǎng)方面的知識，能進行有關營養(yǎng)成分的簡單計算。2.會用已有的知識選擇營養(yǎng)配餐和評價配餐營養(yǎng)成份的均衡性。3.通過營養(yǎng)配餐的活動，體會數(shù)學知識的應用，發(fā)展數(shù)學應用意識和提高學生解決問題的能力。教學過程：一、激趣引入。1、觀察我國運動員在積極備戰(zhàn)2008年奧運會的圖片。師：2008年奧運會在我國舉行，我們?nèi)珖嗣穸几械椒浅５尿湴?。打開課本p46觀察圖片，我國運動員在積極備戰(zhàn)2008年北京奧運會。運動員要取得好成績，自己的身體機能一定要達到最佳狀況，運動員在訓練中需要根據(jù)營養(yǎng)標準合理

2、搭配食物。我們了解一些營養(yǎng)配餐方面的知識！2、 板書課題：營養(yǎng)配餐師：營養(yǎng)配餐就是使每一餐攝入的各種營養(yǎng)成分要充足，還要均衡搭配。食品的營養(yǎng)成分很多，我們只是討論蛋白質(zhì)、脂肪、碳水化合物這三種成分，它們是人們獲取熱量的主要來源。3、 我們一起來了解運動員的營養(yǎng)配餐情況。出示小資料（讓學生閱讀小資料。）4、 運動員有運動員的營養(yǎng)配餐，我們小學生現(xiàn)在正在長身體的時，我們也有我們的營養(yǎng)配餐。今天，我們一起來討論有關我們營養(yǎng)配餐方面的問題。為了使配餐科學，科學家給出了一些營養(yǎng)標準，以及一些食物中所含營養(yǎng)成分的含量。（出示食物中蛋白質(zhì)、脂肪、碳水化合物的營養(yǎng)成分含量）二、設計與展示?；顒右唬号袛辔绮偷暮?/p>

3、理性。1、觀察課本“100克各種食物所含營養(yǎng)成份的統(tǒng)計表”，說一說自己所獲得的信息。2、小組合作通過計算判斷小明的一份午餐選擇得合不合理。、師出示小明的菜譜，問：小明這頓飯選擇得好不好？為什么？、完成算一算：蛋白質(zhì)、脂肪、碳水化合物是人體所需熱量的主要來源，先來算一算這三種的含量吧！3、小組匯報，提出合理化建議。師：小明的菜譜中，上述哪種營養(yǎng)成分基本符合營養(yǎng)師的建議？哪種營養(yǎng)成分與營養(yǎng)師的建議有較大出入？你能幫助小明重新設計一下嗎？活動二：“洋快餐”的小調(diào)查。1、 調(diào)查一份洋快餐的份量。營養(yǎng)成分。2、 計算判斷一份洋快餐是否有營養(yǎng)。3、 展示洋快餐營養(yǎng)成分的調(diào)查結(jié)果。4、 學生進行交流。三、總

4、結(jié)這節(jié)課我們運用了百分數(shù)的知識進行營養(yǎng)配餐中食物營養(yǎng)成分的計算，我們還了解有關營養(yǎng)方面的知識，知道了我們正在長身體，不能挑食，營養(yǎng)要均衡。四、作業(yè)：活動三：我是小小營養(yǎng)師查查有關資料，為爸爸媽媽設計一份營養(yǎng)豐富，美味可口的晚飯。并簡要說明設計的理由。有能力的同學還可以自己做一頓這樣的晚飯。qcwa3ptgz7r4i30ka1dkaghn3xtkknbycudxqa7fhyi2chhi92tgkqcwa3ptgshls50clmtwn60eo8wgqv7xav2ohum32wgeauwydiawgmer4i30ka1dkaghn3xtkknbycudxqa7fhyi2chhi92tgkqcwa3
