Student identifies
the same land mass or body of water in each of two images
obtained from two different time periods.
|
Land or body of water
chosen to measure is not the same on both photos/maps.
|
Land or body of water
chosen to measure is the same but blocked off / outlined
incorrectly.
|
Land or body of water
chosen to measure is the same and the outline drawn
has no more than 2 flaws.
|
Land or body of water
chosen is precisely outlined to make measurements more
precise and easier.
|
____
|
|
Student draws simple
shapes (ie. rectangles and triangles) on the image in
order to calculate surface area.
|
Very few shapes are
drawn leaving much room for error in finding surface
area.
|
Few to moderate number
of shapes are drawn to measure to calculate surface
area.
|
Moderate number of
shapes are drawn to break up the image to calculate
a more precise surface area.
|
|
____
|
|
Student measures
dimensions of basic shapes and finds the area of those
shapes.
|
The use of the map/photo
scale is not evident in the measuring process,the formulas
used for area are incorrect, or too many arithmetic
mistakes are made.
|
The use of the scale
is evident, however the measurements are not precise,
but the formulas are correct.
|
The student correctly
uses the scale, is precise with measurements and formulas
are used correctly to calculate area.
|
The student correctly
uses the scale, is precise with measurements with units,
and formulas are used correctly to calculate area
|
____
|
|
Student uses addition
or subtraction of simple shapes to find the surface
area of the land mass or body of water.
|
Did not complete this
calculation.
|
Calculation is completed
but some simple arithmetic mistakes are made.
|
Student correctly and
precisely finds the surface area of the land or body
of water.
|
|
____
|
|
Student writes a
statement concluding if there is a change in area or
not and supports with math.
|
This statement is not
made, or no comparison is made.
|
Work is shown to find
a comparison between the two images, but no coherent
statement is made.
|
A statement comparing
the surface area of the location at different times
is made and has work to support the find.
