Lesson Plan Description

Really understanding that subtraction and addition are related is more complicated than memorizing math facts.  Help your 1st graders “see” and explain the relationship in this 2 segment bundle of lessons.  Your students will:

  • Segment 1: collaborate with their peers to practice the “language” and “why” of the Addition Commutative Property, practice subtracting as an unknown-addend problem using manipulatives, and display their understanding of using subtraction as an unknown-addend problem
  • Segment 2: play a “game” in order to demonstrate their understanding by turning subtraction problems into addition problems

These lessons can be taught over the span of a half day or you can use the lessons independently, broken up over several days.
