# GM4-4: Interpret and use scales, timetables, and charts.

Elaboration on this Achievement Objective

This means students will be literate in getting required information from the following:

- Scales, such as thermometers, analogue (and digital) clocks, rulers, protractors, weight scales, capacity containers.
- Timetables, such as those used in transport (12 or 24-hour time), tides, broadcast programming, telephone books (international calls), sports events.
- Charts used to convey measurement information, such as weather reports, cooking recipes, Guiness Book of Records, statistics on living organisms.

At Level Four it is expected that students will use the information from scales, timetables and charts in the course of solving problems and select information that is relevant to solving the problem.

Teaching resources for this Achievement Objective

The purpose of this unit is to engage the student in applying their knowledge and skills of measurement to solve problems involving food technology.

Students develop their skills and knowledge on the mathematics learning progression, measurement sense, in a food technology context.
