In this lesson, students solve subtraction problems using paper-and-pencil methods. They begin by recording their work with base-ten pieces on base-ten recording sheets. Then they use the standard paper-and-pencil subtraction algorithm, the compact method, to solve problems. They check their work with addition.

Content in this Lesson

  • Solving multidigit subtraction problems using paper and pencil [E4].
  • Using place value to make connections among representations of number to the thousands using base-ten pieces [E1].
  • Representing and solving subtraction problems using base-ten pieces [E2].
  • Checking subtraction problems with addition.
