Commentary:
Students at both year levels enjoyed quite good success with this task, except when subtracting 1000 from 27,492 at year 4 level or .01 from 10.1 at year 8 level. Year 4 boys scored significantly higher than year 4 girls and many year 4 Mäori and Pasifika students found the task difficult.
