This is my go to warmer activity when I need something quick, fun and energising! For each slide I take about 5 minutes.
I show the slide and give the students 30 seconds to discuss the pronunciation and see what words they can translate.
I then pounce on students to elicit the pronunciation and translation.
Then I gradually drill the tonguetwister, bit-by-bit.
When the students can recite the whole tonguetwister I challenge them to say it 3 times as fast as possible and then either ask for volunteers or pounce on individual students.
Often the shortest tonguetwisters e.g. Seize chaises sèchent! are the most difficult.
