• "Some of us caught on quickly. But majority found it tricky. Drawing coins helped to explain the answer."

• "You should have been more specific with the wording and said that the tails were turned over."

• "The wording of the question is fine. If 1/2 of the coins start as tails up, and, when 2 are turned this becomes 1/3, it should be obvious that it was tails that were turned because 1/3 is less than 1/2."
• Gabriel, Edgware

• "The wording is a problem...
  If you started with 6 coins and turned one head and one tail over, you would get to 1/2 and 1/3.
  Surely?"

• "The majority of our class found this very confusing at first. However, Lewis in our class worked out the answer very quickly: he worked out that if he thought of a number on the 2 times table, and tried to take 2 away to see if it was on the three times table then he would have his answer...
  The rest of the class were most impressed!"
