Update 2022
I've added a three choice quiz to get what jobs Hello Kitty wants. There are 8 questions so you might want to cut them down a bit if you want to do everything in one lesson. Also there are two versions of the quiz. The first uses all relative pronoun hints and the second uses one relative pronoun hint and the others regular sentences. I prefer that since I feel it sounds more natural but check with your teachers. The other activities remain the same.
The attachment includes a few activities.
The last page is the karuta cards. They should be cut out one set per group.
I usually start with karuta in groups played twice. The first time I just call out the occupation names.
The second time I call out a hint 'they are people who stop bad people' and then the answer. In both cases students listen and slap the card they think is correct.
The first page should be printed out one per group. This is for pattern practice. It has some key vocabulary students can use the make sentences. They pick an occupation and make a sentence about it. For example 'They are people who stop fires'. One member goes to a teacher and speaks their sentence. The teacher tries to guess the answer and if correct checks that picture. The student goes back and they continue trying to make another quiz for the teacher. Set a time limit and see how many quizes the group can make for the teacher. Maybe reward stickers if they complete a certain number of quizes. Or use a point get game to increase the motivation.
Finally a writing page. In groups, pairs or alone they should write about occupations they respect.
