Here are some Present Continuous Conversation Questions that you can use with your students. They’re in the form of a board game but I guess it can be adapted. I tried to include as many situations as possible that would prompt them to use the Present Continuous in their answers. If you choose to use this with groups of students, make sure they ask each other plenty of follow-up questions. Use the dice if you have groups of four playing or you can just put the question numbers 1 to 22 into a hat and have them draw the numbers one by one.
Let me know how it goes and if there’s anything I should improve.
Happy learning!: )
