Little did I know, she was throwing me into teaching math 30 seconds from that very moment. The topic of the math lesson was about the metric system...something which I have a basic understanding of but was nowhere near comfortable teaching by myself to 20 students. However, my teacher had an emergency and I needed to take over!
This wonderful image perfectly portrays how myself as well as the rest of my students feel about the metric system. We don't use the metric system very often in America, but the rest of the world does. It is logical, but we don't use it. Hmph.
Fortunately for me, most of the students had some experience working with the metric system before my stellar un-planned lesson. After a 10-minute introduction about how to read a ruler and convert between centimeters, millimeters, meters, etc, I had the students go around the room and measure certain objects. They broke up into partners and worked together to do this.
Upon reflecting on this lesson, I realized that it would have made much more sense to explain the conversions in powers of 10. In order to convert between units, I should have showed that you simply multiply by 10. Next time I'll tell my class this!
