Working with teachers in my my building I created a degrading average standards based Gradebook. The degrading average can be changed to fit your needs along with entering your students information on the first page so that it will transfer to each tab. Everything I have created from scratch to fit our needs. Upon purchase I will share a link that you can then copy to use as your own. I will support your questions as well as make changes you would like to see. All I ask is that you give it a try and help me grow this. Since it is a Google Sheets not sure how to download it for distribution but if you email me firstname.lastname@example.org I will make sure you get it ASAP.
