We will be having a test on Tuesday, October 19 over the material we have covered so far.
Below you will find a mixture of Learning Targets. Working with a partner, each of you
needs to pick a column to do. Partner 1 will do column A, Partner 2 will do column B. While
the problems themselves are different, the final answer to the problem is the same. Check
your answer with your partner. If you get different answers, work together to find the error.
