| 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 | ||||
