Activity Overview

Students will explore patterns related to place value in calculations.

Before the Activity

  • See the attached PDF file for detailed instructions for this activity
  • Print pages 5 - 8 from the attached PDF file for your class

    		•

    		During the Activity

    		Distribute the pages to the class.

    Follow the activity procedures:
  • Enter 5 single-digit numbers and use each digit once to create a problem containing a one-digit number multiplied by a four-digit number
  • Interchange the digits and record the products each time
  • Estimate the largest possible product for the problem
  • Understand that the largest digits should be used in the largest place value positions to maximize the product
  • Realize that the smallest digits should be used in the largest place value positions to minimize the product

    		After the Activity

    		Students complete the Student Activity pages and list the largest and smallest possible answers for each combination of numbers.

  • Review student results
  • As a class, discuss questions that appeared to be more challenging
  • Re-teach concepts as necessary
