Product Description
Litter in the USA is a themed activity to demonstrate how rates and ratios can be applied to real world situations.

Data based on the 2009 Keep America Beautiful National Visible Litter Survey and Litter Cost Study shows that over 50 billion pieces of litter appear along U.S. roadways each year. During this activity, your students will :

1. Construct ratios to analyze and compare data.

2. Interpret the meaning of a ratio as it applies to a real word phenomenon.

3. Use simplification of ratios to calculate "unit ratios" (occurrence rates).

4. Use data from tables to calculate litter rates for specific trash items per 1 mile of U.S. highway and to calculate litter rates (in percents) for various types of trash items.
