In all honesty...I lose quite a bit. I did the math and I teach 64% of the day if you count independent work times and silent reading in the time I am teaching.

250 a week for specials(PE, Library, Computers)-these are not preps and I have to attend all of them and am not allowed to work on other work but I am not "teaching". WE also have 30 minutes a month of music.

125 minutes a week are lost to transitions into the classroom, out and back from recess, out and back from lunch out and back to a "special" outside the classroom and packing up. This includes taking attendance and announcements since attendance is just a couple minutes and we only have announcements once a week.

250 minutes a week for recess and lunch.

Some of the other non-core subject teaching areas vary A LOT-like art which we can only do if we get to it after we have done all the core instruction.

WE have assemblies and class reward times for things like good attendance at least every other week for 30-45 minutes as well so if we are coming up with a weekly average I'll just subtract 20 minutes

So if school is 1800 minutes a week and we subtract off 645 minutes thats 1155, Now I will divide it by 5 school days a week, and then further divide it by 60 minutes in an hour whats left

3.85 hours of instruction which is 64% of the day... gosh that makes me feel really bad about doing things like silent reading since I already lose almost half my instruction time as it is...but they need the eyes to text time...
