When young students begin working with volume, it can be hard for them without visualization. This free downloadable worksheet gives them practice with colorful pictures of familiar objects and lets them decide which of the containers holds less than the other. It's a great beginning sheet for students to build up to when they'll work on comparing numbers using greater than and less than symbols.
