If a student is having trouble writing or typing his/her thoughts on paper, consider voice-typing in Google Docs. This allows the student to talk out ideas and is helpful for those who have difficulty typing as quickly as the thoughts come into their head. This is also great accommodation for students with written expression disability.
In a Google Doc (and Slides), go to the Tools menu and select Voice typing. Punctuation is not automatically included, and your child will need to do some editing after voice-typing. Check out this 2-minute video demo!
