One of the most useful little tools I've been using in my online teaching so far has been Telegram Polls. If you have a group of students in a Telegram group, you can send polls in a "quiz mode" to students in order to check their knowledge. This can be done during class or even after or before to utilize a TTT type lesson. Here's how you set up a poll. If you're using your phone with Telegram, open a group chat or channel. Then tap on the paperclip in the lower left-hand corner. Select poll. Then you can write your question and include up to 10 possible answers for students to select. Before you post it, make sure you select "quiz mode" if there is only one correct answer. In group chats, you also have an option for making your quiz anonymous or not, so you can see who is struggling the most in your class. This is also a good way to replace monitoring in your normal face-to-face class since you can't always see if they've gotten the right answer...
For all things good and helpful related to English language teaching both at home and abroad.
