This is a PowerPoint lesson and note-taking guide that teaches adding and subtracting rational numbers with common denominators. I use the PowerPoint on my smart-board and upload it to goggle classroom for students if they need extra help or if they were absent for the day. You will find that as you go through the PowerPoint, students can take notes on their note page which we put into our math interactive notebooks. The PowerPoint is editable and has 11 slides. It teaches adding and subtracting fractions with negatives and variables.
