MAT-07.NS.01.c

7th Grade MAT Targeted Standards
Domain (NS) The Number System
Cluster: Apply and extend previous understandings of operations with fractions to add, subtract, multiply, and divide rational numbers

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.

MAT-07.NS.01.c Understand subtraction of rational numbers as adding the additive inverse, p – q = p + (–q). Show that the distance between two rational numbers on the number line is the absolute value of their difference, and apply this principle in real-world contexts.

Student Learning Targets:

Knowledge Targets

  • I can show the distance between two rational number on the number line is the absolute value of their difference
  • I can use the additive inverse to write a subtraction problem as an addition problem

Skills Domain (Performance) Targets

  • I can subtract rational numbers in real world contexts.
