Abstract
The data from national tests such as the National Assessment Program Literacy and Numeracy (NAPLAN) and its precursor Victorian Achievement Improvement Monitor (AIM) are an important resource. The 2006 Year 3 AIM assessment included two subtraction items that are similar in content, and which were presented without text or images. The detailed, novel analysis of the children’s responses presented here provides insight into children's fluency and understanding of these items.
