Shapes
 
or
 
groups
 
of
 
shapes
 
can
 
be
  
classified
 
by
 
their
 
properties
 
 
Two-dimensional
 
shapes
 
are
 
combined
  
to
 
make
 
three-dimensional
 
shapes
 
 
Area,

Shapes
 
can
 
be
 
described
 
in
 
terms
 
of
 
their
  
location
 
and
 
viewed
 
from
 
different
  
perspectives;
 
geometric
 
figures
 
can
 
be
  
moved
 
in
 
a
 
plane
 
without
 
changing
 
their
  
size

“Perhaps

the

first,
  
understanding

of
 
measuring
 
a
