Research 1: Ancient Numerical System
INTRODUCTION Almost every culture both past and present has had the need for numerical representation. It is not entirely clear which was the first culture to invent a number system (Babylonians, Egyptians, Greeks, etc.) but the need was evident. One of the first and most famous number system is the Greek numbers. The Greek's used the letters of the alphabet to represent both numbers and operations. The following is an example of ancient number systems: The numbers that are used in our society hasn't changed for approximately three hundred years. One question that is still being tossed around by some mathematicians is: "Approximately every two to three hundred years the visual representation of the numbers has changed. Will there be another change to the way society write numbers?" 
PROJECT TASK This project is a joint mathematics and social studies activity. The grouping will be as follows: Group 1: Index no. 1,2,3 Group 2: Index no. 4,5,6 Group 3: Index no. 7,8,9 Group 4: Index no. 10,11,12 Group 5: Index no. 13,14,15 Group 6: Index no. 16,17,18 Group 7: Index no. 19,20,21 You are to conduct a research into one of the following ancient numerical systems:
A. RESEARCH FOCUS In the research, focus on the following aspects:1. The historical development of the numerical system of the the ancient civilization assigned. a. How was the numerical system developed? b. The social or cultural background behind the development of the system i. Who developed the numerical system ii. Why was it developed? What function did it serve? (eg. Used in trading, education, communication etc) 2. The number system a. Properties of the number system i. Is there repetition of symbols used (looking from the historical perspective of ancient number systems ii. What base is used in the system iii. Is there a symbol for zero? b. Pictorial or symbolic representation of the various numbers (if any) B. PRODUCT AND SUBMISSION The objective of the poster is to educate someone about ancient numeration system. As such, your poster should be written for a reader with a knowledge level equivalent to that of someone in lower secondary but ignorant about your particular topic. Keep your topic narrowly focused. Feel free to go as far with this as you like! Present the researched information on an A4size poster. Submit a printed copy as well as upload a copy to your Class Maths Blog. The writeup should have the following information: Header:

Content:
One class period will be allotted for introduction and groups’ discussion, but afterclass time will be necessary to complete your research work and chart.
