## For **BOTH PERIODS**

I have some ideas of how homework accountability might change for our class. Please complete this Google Survey about homework. The survey is completely anonymous. Please be honest!

## For Period 3

We spent today practicing adding, subtracting, multiplying, and dividing with an IXL assignment. Your homework is one of two:

- Complete the three IXL modules linked below to a score of 80 or higher (or spend at least half an hour trying on each)
- Complete HW 2.6 – More Practice with Operations

## For Period 8

We did some more work with adding/subtracting rational expressions today, this time with polynomial denominators. The key thing to remember with these is that **we can only obtain a common denominator through multiplying**. We cannot add/subtract denominators. See the notes and the video below for examples.
