An OTJ draws on multiple source of data to make a judgement about their ability in comparison to national standard. You can't just use one piece of evidence as this is hazardous to forming a true picture.
Type of evidence you will include are:
and other group work.
To make a judgment you will need to use the The New Zealand Curriculum Mathematics standards poster, the standards books and additional illustration.
We also need to remember that just having the answer it is not enough it is about how they explain how they know it.
While the number is the most critical requirement, strand include geometry, measurement and statistics.
We also must remember that number knowledge is used to facilitate problem solving. Knowledge is important but it is there to help you with strategies.
When forming our OJT we need to think about are they able to do it independently and most of the time.
We need to think about how we are tracking all of this data overtime so that we don't have to go back to each individual sources each time. This can be done in many ways.
