6. Procedures/Methods

A. Introduction
1. Endangered Species
2. How many endangered species exist?
3. Is the number of endangered species increasing or decreasing?



B. Development
1. What organizations exit to help these species?
2. Provide students with a list of endangered species.



C. Practice
1. Students will choose one species of the list.
2. The first task is to determine when these species became endangered.
3. Students will shared discoveries with class. 


D. Independent Practice
1. Students will be asked to research about their animals and find
a minimum of ten facts.
2. The facts will be transformed into an informative poster to present
to the class.
3. All students must find out how many members of there specie existed
in the past 25, 20, 15, 10, and 5 years.
4. This information will be transformed into a chart comparing how
many remained 25 years ago in comparison to the other years.
5. The chart will contain the ratio in fractions, decimals, and percents. 


E. Accommodations (Differentiated Instruction)
1. Students can work in groups of two. This will prompt social interaction
and group analysis.
2. Students can watch a video about endangered species at the beginning
of the lesson. This may encourage student engagement and present interest
in the topic. 


F. Checking for understanding
1. Students posters will be graded in terms of creativity and accuracy.
2. Students charts will be evaluated on whether the fractions were
properly transformed into decimals and percents.
