Give students various size containers, such as bowls, jars and food storage boxes. Show them the measuring devices for a cup, pint, quart and gallon. Ask the students to determine which measurement device they would use to fill each container. They should also estimate how many of the measurement until it would take. Students will record their answers and then conduct the activity to see if their predictions were correct.
Choose several different shape containers. Some of the containers should hold the same capacity of liquid. For example, use different shapes of pint containers. Empty drink and food containers often work well because they come in various shapes and sizes but often have the same capacity. Show the students two containers at one time. Ask the students to determine which container holds more or less or if the two are equal. Reveal the answer by using a measuring tool to fill both containers or by pouring one container of liquid into the other.
Divide your students into groups. Have the student groups write and record a rap song that details the conversion of customary weight units and items that would be measured using each weight unit. Validate the verses for accuracy and then allow the children to record their rap using a computer program or CD recorder. Compile a CD of the raps for the students to listen to for review.
Allow each student to obtain his weight in pounds using a scale you have brought to class. Offer the students an opportunity to use the weight of a different person or of an object if the student is reluctant to reveal his weight. Ask the students to create a chart that gives the measurement in each customary weight unit.
