# Max Maths, Year 2, Learn together, Units of volume (1)

In a Year 2 mathematics lesson about units of volume, students are introduced to the concept of measuring the volume of liquids. Through a practical example, Han is curious about the volume of orange juice in his glass and decides to measure it using a measuring cylinder. This common laboratory equipment is marked with scales to indicate volume in millilitres (ml). When Han pours his orange juice into the measuring cylinder, the level of the liquid rises to the 300 ml mark. This indicates that the volume of the orange juice is precisely 300 millilitres. The lesson underscores that millilitres are a standard unit of measurement for volume, which makes it simpler to compare different amounts of liquids accurately.

The lesson emphasises the importance of using standard units such as millilitres to measure volume. This standardisation ensures consistency and ease of comparison when dealing with various quantities of liquids. The measuring cylinder, with its clear and precise scales, provides an effective visual aid for children to understand the concept of volume. By observing the 300 ml mark reached by the orange juice, students learn to associate the term 'ml' with millilitres and grasp the basic idea of measuring and comparing volumes in a standardised way. Such foundational knowledge is crucial as they progress in their mathematical understanding of volume and capacity.
