Max Maths, Year 3, Learn together, Adding and subtracting volumes (1)

In the Max Maths Year 3 curriculum, students are introduced to the concept of measuring and calculating volume, specifically through the practical application of adding and subtracting volumes. A relatable example is used to illustrate the concept: Tya has a flask full of water which she wants to measure. To determine the volume, Tya pours the water into a measuring cylinder, but since the flask contains more water than the cylinder can hold, she uses a second measuring cylinder for the remaining water. The lesson then focuses on combining the volumes of water in both cylinders to find the total volume originally in the flask.

The exercise demonstrates the process of addition to find the combined volume. Tya first fills one measuring cylinder to a certain level and then pours the leftover water into another cylinder. By reading the measurements on both cylinders, students learn how to add the separate volumes together. The example given shows an initial measurement of 1 litre in the first cylinder, and an additional 140 millilitres in the second cylinder. By adding these amounts, students find that the total volume of water Tya had in the flask is 1 litre and 140 millilitres. This practical approach helps students understand how to work with different units of volume and reinforces their addition skills in a real-world context.
