Trigonometry Lesson Plans

Nothing to do for Week 5! 

I am so proud of all of you and the work that you did! 

If you do not have the grade that you wanted, you may work on the Aleks Pie for bonus. You will get 2 points bonus for each % point earned. So if your Knowledge Check was a 50 and you raise it to a 55, then you will get 10 points bonus.

The deadline for bonus to be in is 3:30 pm on Friday, May 8.

***Semester grades will be cumulative, not 50/50 – so the grade you are seeing is your semester grade!
