This is a great Power Point to introduce the metric system. It talks about the English vs. the Metric System and how to measure Length, Width, Height, Solid & Liquid Volume, and Mass vs. Weight in metric!
The end of the power point displays the "Ladder Method" and how to use this to convert metric measurements from meters to centimeters, etc. The last page includes a problem to do together, and some practice problems the kids can do in their notebooks, and then do on the board as a class!
Metric measurement is used in science so that ALL scientists around the world can compare data without having to convert and estimate numbers from the American system to the Metric System!
