Commentary:
In
question one, many students showed a lack of understanding of the term
‘rärangi hangarite’ by drawing a vertical line between
the two sections of the pattern. Performance in question two was considerably
better where students were required to manipulate sections of a köwhaiwhai
pattern to sit correctly within two lines of symmetry.
