Meter stick
A meter stick or ruler measured straight lines
Opisomiter
Can be used to measure short curved lines for example a road or river on a map
Trundle wheel

Mass
Is the amount of matter in an object
It is measured in the lab using an electronic balance
Area
How much space something covers
Length x width
Irregular area
Use graph paper and count squares
Volume
Find depth by width by length
How much space something takes up
Irregular shaped objects
We can measure the volume of irregular object using a graduated cylinder and or a overflow can
