Engaging Esti-Mystery Charts for Rich Math Talk
I see 3 versions of this Esti-Mystery. Which one should I use?
“Esti-Mysteries are already working well for my class.”
Use slides 2-7 if Esti-Mysteries if your students have charts to write on.
You’re students are writing on a
chart, writing down their estimates, and are discussing their ideas with each other after each clue. They
may be writing on paper, writing on a dry erase surface, or using a digital tool to annotate – or they have
another way of responding to clues in writing. You probably already notice that when students write down
their estimate after each clue it helps to propel rich math talk and also builds anticipation for the next clue.
If this sounds familiar, then I recommend using slides 2-7.
“I need to display a chart for everyone to see, and I have a way to write on it.”
Use slides 8-13 if you simply need an embedded chart to write on during discussion
. This may be helpful if
you want to show a chart at the same time as the Esti-Mystery. The chart (on slides 8-13) will appear on the
screen so that you can write on it. You can simply write on your whiteboard , use a digital pen, or use the
chart in may other ways.
“I need a step-by-step animated chart that eliminates numbers after every clue.”
Use slides 14-19 if you want to see numbers disappear from the chart after every clue.
This may be helpful
if you need a chart and don’t have an easy way to write on the chart. After each clue, you’ll see which
numbers are eliminated – and which ones are left.
Watch this YouTube video for more
information about the charts.

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.
How many ducks are in the glass?
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.
