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.
How many balls are in the vase?
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.
