Mass Year One 2017 Victorian Curriculum Success Criteria- Know, Understand, Do Novice Competent Expert Use direct and indirect comparisons to decide which is longer, heavier or holds more, and explain reasoning in everyday language (VCMMG078) Foundation Use appropriate language of approximation (heavier, lighter) and comparison to describe the attributes of objects with regard to mass Measure and compare the lengths, masses and capacities of pairs of objects using uniform informal units (VCMMG095) Year One Compare the mass of familiar objects using descriptive terms such as heavier / lighter. Estimate and compare the mass of two objects using hefting or a beam balance Estimate and measure using informal units; for example, bricks for weight. Use informal units; for example, handfuls, counters; to estimate, measure and compare masses Find objects heavier/lighter/equal to a given object or unit of measure Compare and order several shapes and objects based on length, area, volume and capacity using appropriate uniform informal units (VCMMG115) Year Two Select and use the appropriate attribute when responding to measurement questions and select units of measure suitable for measuring mass Use ‘between’ to describe measurements; for example, it weighs between 7 and 8 marbles Understand that different attributes can lead to different results when ordering; for example, this bottle is taller than but weighs less than this bottle Recognise the differences between non-uniform measures and uniform measures Compare masses of objects using balance scales(VCMMG116) Year Two Estimate and compare objects to make judgements of comparison relating to mass by hefting Use the formal unit, kilogram for mass Measure, order and compare objects using familiar metric units of length, area, mass and capacity(VCMMG140) Year Three Use formal units of measurement; for example, kilograms and grams to measure mass Make increasingly accurate estimates of measurements using informal units and standard units Know the need to choose same size objects to use as units when comparing the mass of two objects Estimate and measure the mass of common objects; for example, kilogram of flour Make sensible numerical estimates and use ‘between’ statements to express estimates and measures; for example, I think the book will weigh between 40 and 50 grams They read circular scales; for example, bathroom scales, in measurement contexts Express a degree of confidence in estimates, and try to improve estimates with a particular unit by using it several times to measure different objects; for example, marbles for measuring the mass of various objects Order objects according to numerical measure of mass; for example, the number of marbles needed to balance each object
