[طه زكريا]

Place these numbers on a flipchart or whiteboard:
8,11, 15, 5, 14, 1, 7, 6, 10, 13, 3, 12, 2
Tell the participants, “You’re seeing all the numbers from 1 to 15 with the exception of 4 and 9 . Your task is to decide why the numbers are arranged in this sequence, then put the missing numbers in their proper
places.”

Then tell me , OK?
