Examination
Questions from the Text
Week 1
- Define and compare and contrast standard and non-standard units.
o Non-standard units
• Units from everyday experiences of child
• Less consistent and less accurate
• Informal unit of measure – not recommended for over year 3
• Natural and fun
• Before standard units are introduced, most of the principles associated with measurement can
be developed naturally using non-standard units
o Standard units
• Metric units – Base 10
• Imperial – United States
• Generally agreed upon – consistency
• Universally recognised
• Exceptions in angle, temperature and time
- Why is measurement of length fundamental to developing other measurement understandings?
o Develops a sense of estimation and measurement of the attributes, allowing students to progress to
associated units of measure and recognise the relationship between them
o Early exposure
o Need an understanding of length before the other attributes can be learned

Week 2
- Write a progression for teaching mass and place it in approximate Year levels.
o Mass vs. Weight
• Mass
• The quantity of matter an object contains
• Metric Units – grams/kilograms
• Weight
• Size of the force gravity exerts on an object
• Determined by how much mass it has
• Measured in Newtons
o Measuring Mass
• Introduced in year 2
• Making comparisons
• Heavy and light objects
• Experimenting with beam balances – both masses directly compared
• Comparative statements can be developed – ‘A has a greater mass than B’
• Year 4-6
• Develop a feel for 1kg mass
• Comparisons made between objects that have 1kg mass but differing volumes
• 1kg of marbles, 1kg of sawdust, 1kg of fabric
• Understanding relationships between mass and volume
• Objects with the same mass don’t necessarily have the same volume

Document Summary
Define and compare and contrast standard and non-standard units: non-standard units. Informal unit of measure not recommended for over year 3: units from everyday experiences of child, natural and fun. Before standard units are introduced, most of the principles associated with measurement can be developed naturally using non-standard units: standard units. Imperial united states: metric units base 10, generally agreed upon consistency, universally recognised. Write a progression for teaching mass and place it in approximate year levels: mass vs. The quantity of matter an object contains: weight. Size of the force gravity exerts on an object: determined by how much mass it has, measured in newtons, measuring mass. Introduced in year 2: year 4-6, making comparisons, heavy and light objects, comparative statements can be developed a has a greater mass than b". Discuss the relationship between area and perimeter: no relationship, johnson & norris, 2006, perimeter.
