Bellwork/Jumpstart is an assignment that needs to be started when you enter the class. Sometimes it will need to be completed individually; other times, with class members.
Classwork is just that; work that is done in class. It is expected to completed and turned in by the end of each period. In some cases, you may be able to complete an assignment at home if you have worked hard in class but still need the extra time.
Homework is work that is completed outside of class. You may complete it at home, at an after-school program, in tutoring, etc. It reinforces what we are studying in class. It is due the next day or on its given due date.
Assessments are used to measure how much knowledge you have gained and retained. Many of yours will be in the form of quizzes, tests, and essays. It is important that you do your best on all assessments so that I know what material needs attention.
