  1. Watch this YouTube video for more information about How to Use Esti-Mysteries with Embedded Charts 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 your students have charts to write on. Your 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 many 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.

  2. “Clues and Clasps” 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.

  3. How many clasps 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. Steve Wyborney www.stevewyborney.com

  4. Clue #1 Clue #1 40 and 90. The answer is an odd number between Clue #2 Clue #2 Cross off the multiples of 3. Clue #3 Clue #3 the digit 8. The answer does not include Clue #4 There are some remaining pairs of numbers that have a difference of 10. Eliminate all those pairs. Clue #4 Clue #5 Eliminate the number that is one more than 8 × 5 and the number that is one more than 8 × 9. Clue #5 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
