Practice content from Khan Academy and CK-12 (with more soon) have a "gradeback feature" with Kiddom. When students complete these assignments, Kiddom automatically retrieves student achievement data into the teacher gradebook.
Content that has a gradeback feature will request to connect with you when you select the assignment, like CK-12 below. Once students complete the assignment from practice content, the score they received will automatically be transferred into your gradebook.
The mastery score or percentage the student receives will be applied to the number of points or rubric you originally attached to the assignment. For example, if a student gets 80% of practice questions correct, that will be applied to the points possible in Kiddom.
