End of First Quarter

The first quarter officially ended November 8. I will accept work towards the first quarter marking period until I leave the building on Friday, November 10. The last official grade of the first quarter are the reteaching sheets I handed out on Monday; the Kuta worksheets assigned on Wednesday will count toward the second quarter.
