A long-answer question takes more than plain text. You can write maths, drop in an image, sketch a diagram, or photograph work you did on paper.
Opening a lesson
From your home page, click into the class with the lesson, then open it.
Maths
In the answer box, type / and pick Math Block for an equation on its own line, or Inline Math for one inside a sentence. Type LaTeX, or use the symbol picker.
A photo of your working
Click the + button, then pick a file, drag one in, or use Upload from phone to scan a QR code and take the photo on your phone.
Drawing
The drawing option in the same menu opens a canvas you can sketch on with a finger, stylus or mouse.
Check what we read from your photo
Every file you upload gets read so it can be marked. Under it, File transcription shows what we picked up.
While it is still reading it says "Reading your work...". If it got something wrong, click Edit file transcript and fix it, any time before your answer is marked. Your photo is still what your teacher sees, but the transcript is what the marking reads, so a misread word can cost you marks.
Saving and submitting
Your answer saves as you write. The page-level Submit button hands the lesson in.
