Here is how to set it up:
Select a set of task cards for the activity. Task cards with multiple choice or concrete short answers will work best. Write the answer for each card in small print on the back (possibly in a lower corner). You can use dry-erase pens if you do not want to keep the answers there.
You can also provide blank cards to students and have them write their own question on the card and the correct answer on the back as well. This gives students more ownership but make sure you provide guidelines on how to write questions to get the best quality.
Give each student a task card(s).
Use Hand-Up Pair-Up to mix the students
Partner 1 asks Partner 2 the question on her card. Partner 2 answers (or admits he doesn’t know). Partner 1 acknowledges a correct answer or gives the answer, if needed.
Following the No Opt Out Model if the student has to give the answer require the answering student to repeat in his own words.
The process reverses with Partner 2 asking the questions.
After both questions have been asked, the partners switch cards, find new partners, and the process begins again.
