4. Scale: a way of representing large numbers using smaller numbers. Example Julia uses 936 bars of soap in 78 years. Julia’s scale: 1 picture of soap = 100 bars Total # Scale 936 bars 100 bars = ~9.36 pictures of soap bars 9/27/13 Class Notes – Scales & Scale Keys

5. How do I determine my scale? Total # Scale = Julia uses 936 bars of soap over 78 years of life. ~18.72 pictures of soap bars Julia’s scale: 1 picture of soap = 50 bars Total # Scale = ~9.36 pictures of soap bars Julia’s scale: 1 picture of soap = 100 bars

6. *Rule: The more you use, the larger the scale! *If scale has more than 10 pictures, it will be hard to fit on your graph!

7. Class Notes Example Marcelo uses 5000 tubes of toothpaste in 78 years *Rule: The more you use, the larger the scale! Marcelo’s scale: 1 picture of toothpaste = Total # Scale = pictures of toothpaste

10. Harrison’s rate of consumption = 1 liter a week = 2 a month = 1 every 2 months = 1 tube a month = 5 a week = 1 a month = Twice a month = 4 a year = 1 every 2 months = 5 a month

11. Harrison’s Scale Key = 1000 liters of soda = 468 honey buns = 117 pairs of jeans = 47 tubes of toothpaste = 2535 times I will eat cereal = 47 bars of soap = 208 double cheese burgers = 104 Nike shoes = 117 bottles of shampoo = 780 bananas
