Try one of the techniques from the chapter in your teaching, such as the routine “I think _______ is unreasonable because _______” (pages 90-91) or one of the variations of “My Favorite No” (pages 96-101). You might need to try it a few times to get your students used to the routines (and if you are lucky enough to have a colleague who is also willing to try, plan together and discuss results). Tell us how it went.
