  • Calendar

    Posted on Google Class Work each week is WEEK At A Glance. Students are given a calendar at the beginning of each unit. It will include learning objectives, activities, homework assignments and test/quiz dates for the unit. It is the student's responsibility to be familiar with the dates for assignments and tests/quizzes. If a student is absent the day before a test/quiz, and no new material is covered in class, the student will be expected to take the test/quiz on the scheduled date. 

  • Homework
