Writelike lessons are text first, curriculum second. This means we retroactively map lessons to standards, but it's challenging because most lessons touch multiple standards and it's hard to know where to draw the line.
You can search for a standard in Browse and see which lessons have been mapped to that standard, or you can view all standards mapped to a lesson. However, as with year level ranges, the devil is in the detail and you really need to look at the lesson description and checkpoint to assess if it is right for your needs.
Lessons have been mapped against ACARA (Australia) and Common Core (US).
