From our teachers' playbook

Pour it, fill it, measure it!

What do kids learn about capacity?

Capacity is how much a container can hold. Little learners start with words like full, empty, more and less, comparing a cup to a bucket. In the middle grades kids measure with real units, cups, pints, quarts and gallons, or milliliters and liters, and learn to pick the right one: a spoonful of medicine is milliliters, a swimming pool is liters. By 4th and 5th grade they convert between units, like 1 gallon = 4 quarts = 8 pints = 16 cups. The aha comes when kids pour 4 quarts into a gallon jug and it fills right to the top!

Our favorite ways to make capacity stick

Capacity is a pouring topic, not a pencil topic. Start with water (or rice, if you're brave), then move to paper.

Fill the gallon

Set out a cup, a pint, a quart and a gallon container with a tub of water or rice. Kids predict how many cups fill the quart, then pour to check. Afterward, they record what they found on paper. Pour first, write second.

Why it works: kids understand an idea best when they touch it, then draw it, then write it, the order the U.S. Department of Education recommends for elementary math.

Milliliter or liter? Defend it!

Show a picture, like a bathtub or an eyedropper, and kids hold up mL or L. Then call on someone to explain why. Hearing classmates reason out loud ("a raindrop is tiny, so milliliters!") builds a feel for size that rules alone never do.

Why it works: using clear, consistent math words out loud is one of the U.S. Department of Education's recommendations for elementary math.

Walk through conversions

For older kids, model one conversion step by step out loud: "A gallon is 4 quarts, so 3 gallons is 3 groups of 4." Then do one together and let them try one alone. Seeing the thinking first makes the multiplication make sense.

Why it works: showing first, practicing together, then letting kids try alone is the "gradual release" model teachers have relied on for decades (Pearson and Gallagher, 1983).

Questions teachers and parents ask

What is capacity in math?

Capacity is the amount a container can hold, usually a liquid. Kids measure it in cups, pints, quarts and gallons, or in milliliters and liters.

What is the difference between capacity and volume?

They are close cousins. Capacity is how much a container can hold, while volume is how much space an object takes up. In elementary school, capacity usually means liquids and volume often means counting cubes.

How do kids remember cups, pints, quarts and gallons?

Many teachers draw a "Gallon Man" or a big G with 4 Qs inside, 2 Ps in each Q and 2 Cs in each P. Pouring real containers into each other makes the picture stick even better.

What grade learns capacity?

Kindergarten compares full and empty, and 2nd and 3rd grade start measuring with units. Converting between units, like quarts to cups, usually comes in 4th and 5th grade.
