Part III:  Sharing Your New Knowledge

Meet with your group and teach them what you learned from your Internet research.  Discuss your response to the reflection question on your report. Post at least one thing you learned onto the class wall chart in the "learned" column.  

Part IV:  Creating the New Number System

Draw and name 4 new symbols which will become the digits used in the new number system.  Think about how the number system will work.  Make sure you use place value in designing the new number system.  Will you need a symbol to represent 0?  Will you need a symbol to represent 4? Make sure your symbol designs are simple enough to write quickly, because you will be using them over and over.

Part V:  Presenting the New Number System

1.  Make sure everyone in your group continues to participate as you prepare and present the final project.  

2.  Agree on a visual aid to use for presenting the new number system:  a book, poster, Power Point, or Excel spreadsheet.  Make sure the visual aid includes:

bulleta key with each symbol, name, English translation, and a picture of the number of objects (dots are fine) it represents.
bulleta rule to tell when you regroup.
bulleta chart showing the value of the number one symbol in each of the first 7 columns/places.  The value of each place should be shown in the English number system in its expanded form and as an exponent.
bulleta counting list with the symbols and pictures (dots are fine) up to 70. 

*Note:  If you use an electronic presentation method, you must devise a way to insert your symbols onto the screen, either by scanning or using the objects library.

3.  Practice counting in your new number system using the abacus found at the Internet site:  

  Counting in various number systems

4.  Have each member of your team present one part of the number system to the Zony Tribal Council.  Be sure to clearly show the visual aid and the online abacus for counting.  Explain why place value is an important concept in your new number system.

5.  Congratulations!  Your mission is complete.  You are now free to return to Earth and resume using our good-old base 10 number system.
