Singapore maths and Australian Curriculum Year 8 comparison
We began our comparison of highschool Singapore maths with the Australian Curriculum (AC) at year 7. If you are considering Singapore maths for homeschool year 8, and have come from a school, you should check the Grade 7 comparison to see if your child is prepared.
The difference between the Accelerated and Normal Academic editions becomes more obvious at year 8, and really makes a difference at Year 9 (NA Book 3). (The Accelerated Book 3 covers year 9 and 10 work). More concepts are covered in the Accelerated.
Another difference between these two editions is that there are more questions in each exercise in the Accelerated edition. I always recommend this edition over the Normal Academic as you have the choice of slowing down if you need to (and because I am inclined to train my children to be strong on maths skills). However, if you have a non-maths inclined child and you just want to get what’s necessary covered without a heavy workload, the Normal Academic is the way to go.
You will note that the main lack in Singapore maths at year 8 compared to the AC seems to be indices. However, this is introduced in primary school and used in year 7 and 8. It is advanced in year 9. Other concepts are either on par or advanced.
For more information on Singapore maths and how it has produced the world’s top maths students, read our overview here.
Any differences in content between the Accelerated edition and the Normal Academic (NA) version is because the Accelerated consists of 4 books (covering years 7-11) and the NA has 5 books. Please check the comparison for year 9 (coming soon!).
