This idea comes from my wife, who is an excellent educator, and master teacher (see some of her wonderful blog posts here, here, and here). I love this idea because it is a great way to save myself precious time, and find out who hasn't handed back assignments.
gradebook, input the score, call out the student's name, and then repeat the process with the next student.
When I've recorded the last score, I quickly scan my gradebook to see who hasn't turned in their work. I call those students to the desk, and follow up with them. This is also a good way to find out who forgot to put their name on their paper (A post about never having no-name papers again is found here.)
This plan kills two birds with one stone. I record and hand back the papers in one fell swoop. What a handy time saver it is!
I hope you can use this idea in your classroom tomorrow!
