The ideas involved with studying volume and liquid measurement can be difficult at first for some elementary school students to grasp. Multiplying from cups to pints to quarts and gallons is tough enough, but converting to metric measurements adds a step with decimals that can be messy for young mathematicians. Different activities can help students understand the concepts of liquid volume.

Many different educational websites have worksheets that contain conversion formulas from metric to customary units and back, with problems for students to solve. Generally, these sheets have directions that ask students to make specific conversions in each section, such as cups to litres or ounces to millilitres.
Games such as "Can You Fill It" on the PBSKids website challenge students to fill certain amounts of volume with specific containers without spilling anything. These games challenge children to multiply and divide effectively and use customary and metric units in solving problems.
Effects of Different Volumes
Activities like "Liquid Melodies" from TLC Family take different liquid volumes in similarly sized glass containers and compare the sounds that those containers make when they are struck. Using a 2-liter jar, for example, and adding 1/2 litre, 1 litre, and 1 1/2 litres to them will make instruments with three different tones.
Nesting Measurement Sets
Different manufacturers make measuring cup sets that nest inside one another so students can learn the various liquid measurement units in customary and metric systems. These sets are available in customary units, metric units or both, so students know where the litre fits between the cup and the gallon.
