Students explore the means and extremes of a proportion, the how to make a scale drawing.

Students use hypsometers to measure tall objects.

Eighth graders experiment to decide if a box that is twice as big holds twice a much. They work the concept of volume and how changing dimensions affect it.

Students, after getting information from the past baseball season off the Internet, calculate an attendance-to-win ratio for each of the 28 major league teams and then study the results to see if winning always leads to good attendance.

Students explore how to convert one metric to to another. In this metric unit lesson students are given a worksheet and asked to answer the questions and give and explanation to the class of how they got their answer.
