Notes for Session 3

Note 1

Most Americans are not very comfortable using the metric system. We can't estimate with any accuracy the length of a room in meters, or approximate a kilogram of potatoes. Yet we live in a world that is metric; the United States is one of the few nations that has not converted to the exclusive use of the metric system.

 Part A Notes: Metric System Basics Part B Notes: Metric Units

 This session introduces the key features of the metric system. We examine the relationships between units within the metric system and learn how to represent quantities using different units. You will have an opportunity to develop metric benchmarks by estimating and measuring quantities of length, mass, and capacity. Remember, children who frequently use materials based on the metric system (for example, metersticks and centimeter cubes) will be able to visualize meters, centimeters, grams, and so on and the relationships between certain units.
