Add & Subtract Rational Numbers




 

Videos and lessons to help Grade 7 students learn how to apply and extend previous understandings of addition and subtraction to add and subtract rational numbers; represent addition and subtraction on a horizontal or vertical number line diagram.

Apply properties of operations as strategies to add and subtract rational numbers.

Common Core: 7.NS.1d

Suggested Learning Targets


  • I can identify properties of addition and subtraction.
  • I can apply addition/subtraction properties to strategies to solve mathematical problems. (Note: Task may involve two or three rational numbers.)
