Max Maths, Year 3, Learn together, Word problems (length) (3)

In Max Maths for Year 3, students are presented with practical applications of measurement through word problems that involve length. On workbook pages 169 to 170, they encounter a problem where they need to determine how much longer a truck is compared to a container. To solve this, a model drawing is suggested to visually represent the lengths and facilitate the calculation of the difference between them. The container's length is given as 6 metres and 6 centimetres, while the truck measures 8 metres and 10 centimetres.

To find the answer, students are instructed to perform subtraction: they take the length of the truck and subtract the length of the container. The calculation is straightforward: 8 metres 10 centimetres minus 6 metres 6 centimetres equals 2 metres 4 centimetres. To express the difference in a single unit, they convert the result entirely into centimetres. Thus, 2 metres 4 centimetres is equivalent to 204 centimetres. The conclusion is that the truck is 204 centimetres longer than the container, providing a clear and concise answer to the problem posed in the workbook.
