Gather students so they can see the book and hear the story, Drip, Drop, by Sarah Weeks. This story portrays a mouse that keeps getting leaks in his roof during a rainstorm and chooses to catch the water with different kitchen containers (i.e. a pan or cup). After reading the story, explain that each pair of students will pretend that it has rained in the classroom and will
measure how many cups and tablespoons different containers can hold using the “rain” that fell.
Prepare approximately one quart of water for each pair of students. Also give each group of students three or four different containers with which to measure the volume. None of those containers should hold more than one quart of water. For demonstration purposes, use a quart of water, a couple of empty containers, and a cup for measuring.
Model for the students how to measure the number of cups of water a container can hold by moving one cup from the full container to the empty container. Explain that you are measuring the volume of the different containers. Have the
group count aloud each cup of water you move from the quart you have prepared to the empty containers. When the containers are full, discuss that the volume of the container was __ cups. Repeat the demonstration using different containers or different measuring devices and units. Use non-standard measures for younger students and with those students who need additional experiences with
nonstandard units.
