Addition and Subtraction Within 1,000 Bundle and Game

3rd Grade • Lesson Plan Bundle

Lesson Plan Description

Help your 3rd graders ground their understanding of place value, partial sums and decomposing numbers with this bundle of 3 lessons.  Working together to discuss and explain their reasoning, your students will:

  • Segment 1: collaborate with peers, practice the “language” of math, take notes, use expanded form to decompose a number, identify the value of the digits in order to add using the partial sums method and subtract using the decomposing method
  • Segment 2: practice addition and subtraction within 1000 using open number lines
  • Segment 3: demonstrate their understanding of these skills by playing a game with open number lines to practice explaining value of digits and place values by adding and subtracting within 1000

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