Hello Students, my name is Mr. Lee.  Welcome to my teacher site!  I encourage you to check my site regularly to keep updated on due dates for assignments and exams.  
I use "Remind" to send out reminders for assignments.  You can join my Remind classes by following the directions on my "Remind Access Code" page.  
In addition, you can access some of my powerpoint lecture notes for your classes as well.  
If you are a new student make sure to visit my "Class Rules and Expectations" page to review my class rules and expectations. 
I am excited to have you!  I promise that I will do my very best to help you attain success in my class!  I hope that you can promise me that you will give me your best as well.  
I look forward to getting to know you and to work with you.  If you have any questions or concerns please feel free to contact me or visit me.  
Always with the warmest regards,
Isaac Lee
