Studyladder have announced that all teachers now have access to the NEW Naplan resource page without having to set up a free teacher account. There are free interactive and printable resources for teachers of Year 3, 5 and 7. Furthermore, the activities are tablet friendly, so they will work on most devices. There are an additional 150 NAPLan resources on the site but you need to create a free account. I use Studyladder with my class and it is fantastic.
For teachers out side of Australia, Studyladder is also a free resource with curriculum links for Canada, United Kingdom, United States and New Zealand.
