Important Note:
If you can see this box, then the slide show is
not playing and the reveal won’t work.
Here is the solution:
If you are using PowerPoint, click on Slide
Show, then click on From Current Slide.
If you are using Google Slides, click on View
then Present.
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.
What is the total number
of erasers?
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.
