At the beginning of the class period the students will receive a worksheet that contains a blank metric system ladder and some metric conversions to be competed. The students will then take part in a PowerPoint presentation in which the reasons for using the metric system will be introduced, the ladder method is introduced and a conversion problem is solved using the ladder method. After these three concepts have been introduced (PowerPoint) the students will complete one example on their worksheets.
