Read beakers worksheets
A beaker turns volume into something a child can see. This printable worksheet shows six 1-liter beakers filled to different levels and asks how much liquid each one holds, in milliliters.

The answer key prints on a separate page.
What's on this sheet
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.
Why this sheet works
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.
How this one works
Read the jug
goes up to:1000ml
gaps:10
one gap:100ml
read the bottom of the curve
100ml per gap
gaps counted:8
count in 100s:100, 200, 300, 400, 500, 600, 700, 800
- Work out one gap before anything else. The jug goes up to 1000ml, shared over 10 equal gaps — so one gap is 100ml. Not one — that is the assumption this whole topic is built to break.
- Read at the BOTTOM of the curve the liquid makes, not at its edges — the water climbs the sides a little and the middle is the true level.
- Count the gaps up to it: 8. Now count those gaps in 100s — 100, 200, 300, 400, 500, 600, 700, 800 — so it reads 800ml. Counting the marks alone would have given 8, which is the wrong answer that looks right.
