Year 9 & 10
The Ministry of Education has created an online learning site:
https://learningfromhome.govt.nz/
The other links on this page are to free online learning sites.
Some require no sign in, others require students to sign up for a free account with their email address, and some allow teachers to create classes and send their class a join code. Creating a class usually allows teachers to monitor their students' progress and shows strengths and needs for each student.
Note: when using sites that are not New Zealand based: Year 9/10 NZ = Level 5 NZ Curriculum = 8th/9th Grade USA = KS3/4 UK
Individuals can access the same N4L internet filters as schools use, for free, by going to
https://switchonsafety.co.nz/
to find instructions for individual devices.

You can learn any subject for free, from Y1-Y13 on Khan Academy.
Teachers can set tasks for their class and invite students to join their class using a code.
Khan Academy currently has suggested programmes for each day linked here.
