Grading

I am in the midst of a massive grading session. I am really not the best at getting all of my grading done right away. I have about 175 students of every grade so the first class of 25 is no problem, then you get to kid number 100 and you can't look at the assignment any more.
One of the most difficult parts of being a specials teacher comes with keeping all of the work organized and getting it to the right classes every day. I don't typically have a lot of paper and pencil work in my music classroom.The work I am grading now is assessed this way though due to the nature of the task.
Second graders just finished some note reading work with recognizing the direction of the notes either up, down, or repeated notes as well as writing the notes as a step, skip, or repeat on the staff. This has to be assessed in some sort of paper/pencil way until I have a tech app that can be used across the whole class.
Third grade was writing their own music and performing it. The parts I am grading on paper are the students' writing works. I am checking for their understanding of how to write notes on the staff, put the correct number of notes in a measure, and checking to see if they wrote their own music of just copied my example off the board. It is amazing to see how I can do the example on the SMART board and then take the whole thing down and they can recall exactly what I did and reproduce it with no changes. I had one class where 6 kids came up to me for checks, all having my example note for note.
I also have been watching the videos they took of each other playing their songs. This gives me  a performance grade as well. Can you write it? Can you do it? It is so much fun seeing my students not only create their own work but work together to practice and perform their works.
