Question: which is greater 1 gallon or 4 quarts?
Answer: A gallon is a unit of measurement that is larger than a quart, pint, and cup. You may want to present to your children with an empty gallon carton of milk or a gallon soup pot. With some assistance they can pour 4 quarts into the gallon container to understand that 4 quarts are equal to 1 gallon.
