教學(xué)目標(biāo)：學(xué)生們能識記、拼讀Gr，Br輔音連綴，能分音節(jié)拼讀單詞，由易到難，在繞口令、故事閱讀中提高Gr，Br輔音連綴的復(fù)現(xiàn)率，開闊學(xué)生視野，培養(yǎng)學(xué)生積極的情感態(tài)度。

選取內(nèi)容：以PEP五年級下冊第二單元為藍本，涉及了小學(xué)英語各教材中帶Gr,Br的高頻單詞。

設(shè)計依據(jù)及建議：本設(shè)計依據(jù)短課時、高頻率、多接觸之英語教學(xué)原則而做短課時設(shè)計。Gr，Br輔音連綴各分在三個短課時中完成，每個短課時設(shè)計建議用時三到五分鐘。
