Students will try to match given subjects with their appropriate volume. At first, the students will have to match the cards using the volumes given, which will be in various forms (for example, one will be in cubic feet, one in pints, etc.). After recording their first choice, they will be given a conversion chart. Students should realize that comparing quantities, it is easier once you convert everything to the same unit of measure. After making the conversions, they will try to match the subjects with the appropriate volume. Students will then reflect on the activity.
