### Mathematical Modelling …

● authentically connects to the real world, starting with ill-defined, often messy real-world problems with no unique correct answer.

● is used to explain phenomena in the real world

and/or make predictions about the future behaviour of a system in the real world.

● requires the modeller to be creative and make choices, assumptions, and decisions.

● is an interactive process.

● There are multiple paths open to the mathematical modeller and no clear, unique approach or answer.

## Examples

conducted by Mathematics Education Section, EDB

### Example 1: Paper packed drink

• Unpack a paper packed drink. You should notice that it is formed by folding a piece of paper.

• Use a A4 size paper. Fold it into a half and stick the three open sides with adhesive tapes.

• Fold the paper to make a paper box as shown in the figure.

• Calculate the capacity of the paper box.

(18)

### Example 1: Paper packed drink

• Make another paper box, but with greater capacity.

• How you choose the dimensions? Why? Explain with words and/or diagrams.

• Calculate the capacity of the new paper box.

• Design the paper box with the largest capacity. Show you design process.

• State the assumption you used in the calculations, if any.

The point should then be made that such a survey is inadequate to make general statements about the school (or even young people in Hong Kong) as the sample is not large enough
