Selection of outcomes and content

Using the evidence of learning from the assessment for Area, the following outcomes and content were selected for each tier.

Outcomes	Students learn about	Students learn to
Tier 1 MS1.2 Estimates, measures, compares and records areas using informal units WMS1.2 Uses objects, diagrams, imagery and technology to explore mathematical problems WMS1.5 Links mathematical ideas and makes connections with, and generalisations about, existing knowledge and understanding in relation to Stage 1 content	counting informal units to measure area and describing the part left over estimating, comparing and ordering two or more areas using informal units recording area by referring to the number and type of units used eg the area of this surface is 20 tiles	select and use appropriate informal units to measure area (Applying Strategies) explain why tessellating shapes are best for measuring area (Communicating, Reasoning)
Tier 2 MS1.2 Estimates, measures, compares and records areas using informal units WMS1.2 Uses objects, diagrams, imagery and technology to explore mathematical problems WMS1.3 Describes mathematical situations and methods using everyday and some mathematical language, actions, materials, diagrams and symbols	counting informal units to measure area and describing the part left over drawing the spatial structure (grid) of the repeated units describing why the area remains constant when units are rearranged	select and use appropriate informal units to measure area (Applying Strategies) explain why tessellating shapes are best for measuring area (Communicating, Reasoning) explain the structure of the unit tessellation in terms of rows and columns (Communicating)
Tier 3 MS2.2 Estimates, measures, compares and records the areas of surfaces in square centimetres and square metres WMS2.2 Selects and uses appropriate mental or written strategies, or technology, to solve problems	recognising the need for the square centimetre as a formal unit for measuring area estimating, measuring and comparing areas in square centimetres recording area in square centimetres eg 55 square centimetres using the abbreviations for square metre (m²) and square centimetre (cm²)	discuss and compare areas using some mathematical terms (Communicating) discuss strategies used to estimate area in square centimetres or square metres eg visualising repeated units (Communicating, Reflecting) apply strategies for measuring the areas of a variety of shapes (Applying Strategies) use efficient strategies for counting large numbers of square centimetres eg using strips of ten or squares of 100 (Applying Strategies)
