Hello, David!

Google Classroom grades and Khan Grades via a quiz, or a assignment is always by manual grade. You can check your students assignments and progress on that assgnemnt you assigned by your class. You can grade them accordingly for the grade they got that Khan Academy produces when the assignemt is done. You can check this via the Teachers Interface.

Futhermore, giving a lesson can be also found on the assignment control consisting of mainly 4 questions, and a lesson followup examples of the lesson you assign. Quiz, and main assignments are 6 questions each with no lesson examples, and questions on their own.

If you are confused on making classes, or assigning assignments to a class, please click here for further informations, following other tips on class management.

Hope I helped!
