The Individual Knowledge Assessment of Number (IKAN) forms can be used to determine a student's stages on the knowledge domains.  There are four versions of the form. 

The PDF version provides a single stage across the knowledge domains and is suitable for using as an assessment with an individual student.   

The three PowerPoint versions are designed to be carried out with a whole class.  The recording sheet for these versions is included in the Information for using IKAN PowerPoints file below, and separates the questions into separate knowledge domains.
