A very small number of students correctly answered this question. This is likely, at least partially, because it was expected to be difficult for both year four and year six students.
This question was above the expected minimum level of numeracy performance for year six students and substantially above the minimum expected performance for year four students. Only high performing year six students and very high performing year four students were expected to answer this correctly. Still, only 3% of year four students and 7% of year six students correctly answered this question. Both year levels experienced similar proportions of the various types of incorrect responses.
There may be a need to support students’ critical reading skills, particularly comprehension, so that they can understand the relationships established in these types of questions.
Students may also need support to understand what mathematical concepts mean in context, to better recognise and apply mathematics in ‘real’ situations rather than purely numeric presentations.
