Working on read beakers? Print this sheet as it is, or change the level and questions first.

The answer key prints on a separate page.
Every beaker is drawn with straight sides, which is what makes the scale honest: in a vessel that does not taper the height of the water really is proportional to the volume, so evenly spaced marks mean equal amounts and a level halfway up is genuinely half a liter. The child reads the flat surface of the water against the graduations and writes the amount, the same way they would read a thermometer or a ruler.
The six beakers use different levels across the range rather than clustering near the top, and the water always stops on a printed mark so there is an answer to find rather than one to estimate. Ten graduations to the liter keeps each step a round hundred milliliters — small enough to need counting, large enough that a first attempt is not a guess. The separate answer page prints each amount beside the same beaker so an adult can mark the sheet at a glance.
