Read a scale like a number line: find what each mark is worth, then count up to the water level or the needle.
Watch for: Counting every mark as 1 when the scale counts by 2s or 5s. Reading the top of the container instead of the water level. Mixing up liters (how much) and kilograms (how heavy).
At home: Read measuring jugs and kitchen scales together while cooking: how many grams, how many liters?
