GM4-4: Interpret and use scales, timetables, and charts.
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.
Students develop their skills and knowledge on the mathematics learning progression, measurement sense, in a food technology context.

solve problems involving time zones
measure and interpret qualitative data
- Find whether a given whole number is prime or non-prime (composite) and whether the number is a multiple of three.
- Use exponents, square roots, factorials and place value to write expressions for whole numbers.
- Represent category data using bar charts and interpret those charts.

find fraction of a whole number
solve problems involving addition and multiplication
- describe a method to measure the length of circular objects
- measure length using metres, centimeters and millimeters
- calculate the circumference of a circle from a measurement of diameter
- measure and record data relating to two variables (the dependent variable is the mass of an ice cube; the independent variable is the type of clothing)
- use data to decide which clothing will best guard against hypothermia when tramping.
Students should discover that:
- they can use300
Students develop their skills and knowledge on the mathematics learning progressions measurement sense and using symbols and expressions to think mathematically, in the context of time and motion in sports.
- Understand everyday application of integers.
- Add and subtract positive and negative integers.
- Use models to explain why subtraction of a negative integer has a positive effect.
- carry out a statistical investigation into the relationship between weight, height, and potential energy
- measure and record weight, height, and energy data
- identify relationships in their data, judge their accuracy, and use the relationships to make predictions.
