Published on 06/09/2008

Activity Overview

This App allows students to review how to perform algorithms for the four basic operations. The three modes - the step-by-step mode, fast mode, and the Missing Pieces game allows students to learn, review, and understand the concepts for each operation.

Before the Activity

  • See the attached PDF file for detailed instructions for this activity
  • During the Activity

    Follow the Activity procedures:

  • Select an operation (addition, subtraction, multiplication, and division)
  • Select the mode (step-by-step, fast math, or missing pieces)
  • Step-by-step mode emphasizes place value in the base-ten system for each algorithm
  • Each step of the operation is presented and the student enters values
  • Use the fast mode to review concepts


  • The Missing Pieces game tests understanding of the concepts in the operation selected
  • This timed game provides clues to the answer
  • After the Activity

  • Discuss difficult concepts
