This is an activity for lower intermediate students to review some of the most common mistakes they make in an entertaining way. The students correct the mistakes in the sentences on the board. If they manage to do it correctly, they add either an O or an X to the board until they line up 6 symbols in a row. The mistakes in the exercise are genuine  mistakes made by my own students on a regular basis.

Level: B1

Time: 30 – 45 minutes


  1. To identify and correct common mistakes made by lower intermediate students.
  2. To line up 6 symbols (O or X) in a row.

 Materials (Click on the worksheet below to download the PDF file):

  1. To err is human board game one per team or display on the screen for everyone to see.


  1. Divide the students into teams and display To err is human board game on the screen if you are using Zoom. If you have smaller groups students can also play individually.
  2. To see who starts do rock, paper, scissors.  Whoever wins chooses the square they want to start with. Next the player(s) identifies and corrects the mistake in the square they have chosen. There is only ONE mistake in each sentence e.g an incorrect preposition, article or a verb form etc. If the player(s) manages to do it correctly, they add either an O or an X to the board. The first player to line up 6 of their symbols in a row wins. Since I have been using Zoom I have actually inserted predefined icons ( a star and a heart) when I played with my students as it looked cleaner and much cuter on the screen than an O or an X . You can find the stamps in the annotation tools when you start screen sharing.
  3. Monitor at all times and go through some of the most problematic sentences together at the end of the class. At home 😉 ask students to correct the sentences in all the squares without an icon.

P.S. Thank you for your feedback Mr. Potato. As always taken on board.

P.S. Have a look at one of my activities that has been published on onestopenglish this month ;).
