Let students hear cooking instruction where ~たら is repeatedly used to show the sequence. After the cooking instruction the teacher asks the students the order of the cooking (maybe with using photos), but will not mention the function of the grammatical usage of ~たら at this time.

「じゃがいも、にんじん、たまねぎ、ぶたにくをよういしたらりょうりをはじめます。やさいのかわをむいたら、小さくきります。ぶたにくもきったらおゆをわかします。おゆがわいたら、やさいとぶたにくをいれます。しょうゆ、さとうを入れたらふたをしめます。やさいがにえたら、火をけします。」
