1. Watch this YouTube video for more information about the charts. https://youtu.be/pzPby1HUSQs 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.

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.

3. How many beads 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.

4. Clue #1 Clue #1 The answer is a multiple of 4. Clue #2 Clue #2 The answer is not a multiple of 3. Clue #3 Clue #3 The answer does not include the digit 2 or the digit 1. Clue #4 Clue #4 The answer is not a multiple of 8. Clue #5 Clue #5 that number. Double 34 and eliminate Steve Wyborney www.stevewyborney.com

5. After seeing the clues, you have narrowed the possibilities to a small set of numbers. Before you see the answer, select your final estimate. Write it down, and explain to someone why you chose that number. Steve Wyborney www.stevewyborney.com
