How many discs are in the container? As the clues appear, use the information to narrow the possibilities to a smaller set. After each clue, use estimation again to determine which of the remaining answers is the most reasonable. Write down your first estimate. After each clue, you ll see if your estimate is still a possibility. After each clue, if it is no longer possible write down a new estimate and be prepared to explain why you chose it.
