How to Measure Capacity for the Third Grade
Figuring capacity and volume are math skills that are introduced in kindergarten and taught at other grade levels with increasing levels of complexity. In the third grade, students learn about capacity by participating in hands-on activities in small groups in which the students estimate and compare the capacities of various containers. They also learn conversion formulas through practical experimentation.

Reinforce capacity formulas through visual representation. Many students can memorize conversion facts and tables, but others need frequent reminders. To review liquid capacity, draw a giant "G" on the board or a piece of chart paper. Inside this letter, draw four "Qs" for quarts then two "Ps" for pints, then two "Cs" for cups and the number eight inside the "Cs". This is helpings children remember that four quarts equals a gallon, that two pints equals a quart, two cups equals a pint and 8 fluid oz. equals a cup.

Construct conversion charts in class that students can use to demonstrate the capacity of various containers. Crayola.com has step-by-step directions for making charts to record results of capacity demonstrations using the English and metric measurement systems. Students can make these charts in pairs and compare/contrast results of their findings after filling measuring cups or containers of varying sizes.

Teach capacity with a practical liquid capacity experiment involving simple, interactive activities in which everyone can participate and practice conversion skills. Have kids pour juice from a gallon container into cups, pints, or quarts to calculate the number needed to hold the entire amount.
