Year 8 maths skills ()« back to years
The skills below are aligned with common core maths and up to 90% with Australian and New Zealand school curriculum. Skills are organized into groups
and are ordered in a way we think would be useful. To master a skill, you will have to gain 10
stars
(In case of a classroom initiated timebound practise session, the time you can practise and the
skill level is determined by your teacher).
There are 3 levels to each skill,
 Easy: A star will be taken away if you get 3 consecutive wrong answers.
 Medium: A star will be taken away if you get 2 consecutive wrong answers.
 Hard: A star will be taken away on each wrong answer.
Most skills have multiple type of questions with varying difficulties. If you keep getting wrong
answers, system may give you the simplest of question to answer. Idea is to
have
you master these skills with a ground up approach.
There is very low probability of getting a question repeated.
If you get a question wrong, you can check how to solve a question correctly and try to get it
right
the next time.
All the best with your online maths practice for Year 8 year. If you see any issue,
