Introduction to Probability, chapter 6
Partner _______________________
During this unit of study you will complete 5 guided labs to develop, practice, and apply
concepts related to the study of probability. You are expected to work collaboratively
with your partner during each class to develop concepts. You are expected to take notes
on each of the 5 labs, assess and clarify your understanding, ask questions of your teacher
as needed, and to complete the homework problems associated with each lab. You are
expected to take responsibility for learning the concepts in this unit.
You will act as a flexible, selfdirected learner. Specifically, you will
Manage your behavior so that you remain focused
Plan and budget time to meet the daily deadlines
Take ownership of your work and your own actions
Prioritize, plan, and manage work to achieve the intended results in a timely
manner
Assess your own work in order to identify areas of strength and weakness
You will act as a collaborative partner in class. Specifically, you will
Understand and commit to the goals of this unit of study
Positively interact with my partner and others in class
Assume shared responsibility for collaborative work, and value the individual
contributions made by my partner and others in class
Provide constructive feedback to my partner and others
After concluding the 5 computerbased lessons we will have a review day in class
followed by a partner quiz. You will be graded on the completion of all of the problems in
this packet as well as your daily level of participation. Specifically, you will be graded on
how you attend to the behaviors listed above. Work intently to develop each of the
concepts in this unit of study and ask for help when you need it.
