Announcement: Starting today, 3.31.17, you may no longer turn in an original assignment late. You must go to the blog to get and complete the alternative assignment, even if you have an excused absence. Late assignments with excused absences need to be turned in within the number of days absent plus one day as per county policy to be considered for full credit. Otherwise, it will be considered late. As always late assignments are worth 80% of the original assignment. Late assignments must be turned in within two school days of the due date for the original assignment.
