1 Estimating Large Numbers
Analyzing Numerical Data

2 How many people will fit in the neon dessert music festival
How many people will fit in the neon dessert music festival? What factors and proportionality will you use? How many people will fit at the Sun City festival? What factors will you need to consider?

4 Counting the number of people at a concert or a play maybe rather simple because you can count the tickets sold. However, finding the number of people attending an event where tickets are not required, such as a parade, a political rally, or a protest, is rather difficult and not very exact. For a political party knowing the number of people attending it is rather crucial and relevant information.

5 To give you an idea of how this kind of problems are solved in real life lets do the following whole group activity. How many students fit in... a. Draw a square on the floor that is 4’ by 4’. b. Students will step in the square, and answer the following questions.

6 How many students were able to fit in?
Explain what relationship exists between the area occupied by your peers and the number of students standing inside the square. As a general rule, people in charge of finding the answer to this kind of questions use the "rule" that states that the average area a standing person occupy is 2 sq. ft.

7 Estimate the size of a crowd that will fit in a 2 mile long sidewalk (assume the sidewalk is rectangular) and it is 20 feet wide. Be prepare to share your answer and the steps that you follow to answer this question. Investigate the dimensions of the school’s football field using any internet browser, how many people could fit there? If you prefer to investigate Time square you may.

8 If the area that a person occupies is 2 sq. ft
If the area that a person occupies is 2 sq. ft. then what would be the area occupy by an average person in square centimeters? In square meters?

9 Summary: Proportions are used in real life situation all the time to make estimations. Also, proportions are used to make conversion within the same measuring system and between different systems. Proportions are actually one of the mathematical skill more often used, so it is a good idea to practice proportionality!
