Please show the cards with the pictures of fruit on them, say the word and have the students repeat after you.
Please show the students the pictures of each fruit and have them repeat after you.
このネイティブの方が果物のカードを生徒に見せ、その果物の名前をネイティブの方の後に生徒に続けて言わせる、という感じでよかったでしょうか？
1) Please show the students the cards with the pictures of fruit on them and have them say the words after you.
2) Please show the students the pictures of each fruit and have them repeat after you.
「生徒に果物のカードを見せる」は
show the students the cards with the pictures of fruit on them
show the students the pictures of each fruit
などと言えます。
果物の絵や写真のカードだと思うので、cards の他に pictures とも言えます。
リピートさせるように言う時は、使役動詞のhave を使って
have the students say the words after you
have the students repeat after you
have 人 動詞の原形 で「人に〜させる」という言い方です。
ご参考になれば幸いです！
