I did a standing speed date with this one.
Students stand up and change cards after asking and answering the questions.
Students come to me to receive a new card if they get the same card again. I kept a tally on the board of how many times each student changed cards, the one with the most points was the winner!
Was great for getting can/can't pronunciations perfected.
This activity was designed for a 30 minute class of pre/low adult beginners.
