Introducing Slope Formula

File for the Post: Introducing Slope Formula

This week, we began our Chapter 3 “Linear Functions” unit. My team introduces Linear Functions by first teaching how to find the slope from two ordered pairs and a given table. We strongly emphasize using the slope formula, since it is on the student's Algebra 1 Formula Chart. 

This year, I decided to create and laminate a “Slope Formula” template for students to write on with Expo Markers (HIGHLY recommend it)! To be honest, I didn’t think a majority of students would like to write on the sheet, but I was wrong. This was very successful (especially in our Algebra 1 co-teach classes).

 

After the notes, students completed the following cut-and-paste activity. Students had to match ordered pairs and tables that have the same slope. Students really enjoyed this activity and felt confident using the slope formula by the end of the class period!

Any interesting ways that you teach the slope formula? Would love to hear more successful teaching strategies!
