1.) Students can discover how a sample can give information about an entire population. Students will estimate the size of a population from a sample. 1. Students are given a dark bag prepared by the teacher containing a total of 100 beans, many red and a few white beans. 2. They are to determine the number of white beans in the bag without looking inside. 3. Students will remove a handful of beans and record the number of red beans and the number of white beans, then return the sample to the bag. 4. This procedure should be repeated 3-5 times. 5. Using proportion, they will estimate the total number of white beans. 6. The mean of the estimates is determined. 7. They can use the mean or another figure as their estimate of the number of white beans out of the total 100 beans in the bag. 8. They must justify their estimate. 9. Students count all the beans in the bag and compare the actual count to the estimates and the mean. Did the white beans represent a sensible sample? 

1.) Students will use proportion to answer problems about sampling. An example would be: A science group catches 500 fish, tags them, and returns them to the lake. Later, the fish population was sampled. 100 fish were caught, 50 of them had tags. Estimate the size of the entire population, and defend your estimation.
