1 The Hook: Can you curl your tongue?

Free, Paid

Students think about curling their tongue, Yes or no? Then they go to Socrative to answer the question.

What do you think the class frequency of the tongue rolling might be? Use a percentage.

Students may think the more common the trait, the better you are, but that is not the case.

Review class data.

Add a short answer question: What other traits do you think you have most in common with your class?

(such as eye color, hair color)
