One of the ways we followed last year with adult-learner classes of English was with the aid of a worksheet.
I wrote for example sentences about a topic. And we worked out the worksheet: reading aloud by me, reading aloud by them, describing the meaning of a word in English, from the worksheet, describing pictures, etc.
This worksheet had usual phrases and meaningful sentences. I also included a short story. If you want to see some worksheet you can contact me at email@example.com . The level varied: B1, B2, C1, within the Common European Framework. / Photo from: www aspentimes com
