What does it mean when we say you have to clean up the problem?

A variaty of answers can apply (you will receive points if your group says something that makes sense)

200

What do these signs indicate: < >

Less than, greater than, need to use open circle when graphing 

300

What do these signs indicate: ≤ ≥

Less than or equal to, greater than or equal to, need to use closed circle when graphing

400

What is the difference between closed circle and open circle?

Closed circle can be used when a number CAN equal the other number, open circle is used when a number CANNOT equal the other number

Can you distribute for the following equation: 

2|-9+6m|+1= 57

No (explain/ review as a group)
