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
