2 2 A student: uses appropriate terminology to describe, and symbols to represent, mathematical ideas MA21WM selects and uses appropriate mental or written strategies, or technology, to solve problems MA22WM measures, records, compares and estimates the masses of objects using kilograms and grams MA212MG Students: Use scaled instruments to measure and compare masses (ACMMG084) recognise the need for a formal unit smaller than the kilogram recognise that there are 1000 grams in one kilogram, ie 1000 grams = 1 kilogram use the gram as a unit to measure mass, using a scaled instrument associate gram measures with familiar objects, eg a standard egg has a mass of about 60 grams (Reasoning) record masses using the abbreviation for grams (g) compare two or more objects by mass measured in kilograms and grams, using a set of scales interpret statements, and discuss the use of kilograms and grams, on commercial packaging (Communicating, Problem Solving) interpret commonly used fractions of a kilogram, including , , , and relate these to the number of grams solve problems, including those involving commonly used fractions of a kilogram (Problem Solving) record masses using kilograms and grams, eg 1 kg 200 g Background Information Refer to background information in Mass 1. Language Students should be able to communicate using the following language: mass, measure, scales, kilogram, gram.
