### Partner Practice

I didn't participate in "My Favorite Friday" this past week but as I think back over the week, I find that I really like setting up Partner Practice.  Basically it's a worksheet.  But there are 2 sets of problems.  Each set has the same answers as the other set.  So partners who are completing the practice get immediate feedback if their answers match ... or if their answers don't match.  So on Friday, I heard great conversations about finding slope when the answers didn't match.  My ninth graders are not really into talking math ... so anytime I can structure an activity that creates the opportunity for conversation, I get excited!

This week's Partner Practice was just a simple basic "find the slope from 2 points" activity. It comes at the end of  a unit in which we have developed slope as rate of change; explored slope and its meaning in graphs and tables.  All of this led up to introducing the slope formula.

All my students completed this activity successfully!
