Data card student says, why do you need to know, fill in the blank? Problem card student says, I need to know, fill in the blank, because dot, dot, dot. Data card student listens to partner's reason and answers with information from the data cards. Repeat cycle until the problem card student can state, I have enough information to solve this problem.
