  # Year 9 On-line

This page links through to some on-line resources for students. The great advantage of these style resources is that feedback is immediate.

The IXL site is good in that it makes questions progressively harder when students answer correctly, but unfortunately it is written for the US curriculum, so sometimes isn't appropriate for NZ students.
