7
1) length
2) are
3) volume
4) mass
5) time
6) angle
7) temperature
What is measurement
The process in which we quantify observable aspects of the world around us
Eg how tall short heavy light hot fat fast
Measurement describes by?
Comparison
Observable aspect is compared to a unit of measurement
Measurements are most easily compared when what has been used?
Standard units
What is the teaching development of measurement?
1) identify attribute
2) direct comparison
3) ordering
4) use of arbitrary units
5) use or standard units
6) nothing of special cases, formula and relationships
When converting from a larger unit to a smaller unit we?

Length
Length is measured in?
Km,m,cm,mm
Length is measured with?
Rulers
Tape measures
Trundle wheels
Odometers
Area is?
The amount of 2D surfaces within a plane shape
Area is measured in?
Square km, square m, square cm, or square mm
Area is measured in square units because?
It involves measuring length in 2 dimensions
1) base and height
2) length and width
What is volume?
The amount of space occupied by a 3D object
What is capacity
The amount an object or container can hold
Volume and capacity are measured with either?
Cubit units or liquid measure
As volume involves measuring lengths in 3 dimensions, what measurement is used?
Cubic units
Volume is measured in?
Cubic meters (m3) or cubic cm (cm3)
Volume and capacity can also be measured in?
Litres or millilitres
1ml =
1 cm3
What is mass?
The amount of matter in an object
