I Have, Who Has – Trig Identities

Standard

The I Have, Who Has… technique is posted on David Pleacher‘s site. Students are handed cards with a question and an answer. For example, the exercise would start with the teacher asking something like, “who has (sin x)/(cos x)?” The student with a tan x answer would reply, “I have tan x” and then read his question, which might be “Who has 1?” A student with an identity equivalent to 1 would reply and the game would continue.
