When I started teaching in 1987, many colleagues had an "EZ-Grader" - a cardboard device they used to calculate a student's percent on an assignment by matching up the number of correct answers with the total number of problems. And by-golly, you can still buy an EZ-Grader for under $2.00.
Then came the 90s and as the world moved from atoms to bits, electronic grade books became one of about a billion adjacent possibles, and most teachers trashed their EZ-Graders. (Seriously, who actually buys an EZ-Grader in 2016?)
