Dividing Whole Numbers: 2-Digit Divisors


Performance Task Objectives

  • Divide by 2-digit divisors
  • Use a formula to find volume


Sunshine State Standards

  • MA.5.A.1.1
  • MA.5.A.1.4

Materials

  • Student recording sheet
  • Paper and pencil
  • Calculator
  • 48 centimeter cubes per student or group

Student arrangement

  • Individual or small group

Task

Present the problem on the student Recording Sheet to your students.

Performance Criteria

  • Does the student understand how to divide by a two-digit number?
  • Does the student show his or her work and exhibit the ability to rearrange the digits to achieve the desired quotients?
  • Is the student able to construct the figure and determine its volume?
  • Do the student’s drawings correspond to the dimensions and volume of the solids created with the cubes?

 

Directions:

1. Two number cubes were rolled and the numbers 6 and 9 were displayed.

The cubes were each rolled two more times with the numbers 8, 3, 7, and 5 being displayed.

 


Using the digits 6 and 9 as the divisor and the 8, 3, 7, and 5 as the dividend, arrange the digits to give the least possible quotient. Show your work to prove your answer. You may check your work with a calculator.

 

 


2. Rearrange the digits to find the greatest possible quotient. Show your work to prove your answer. You may check your work with a calculator.

 


3. A. Using 48 centimeter cubes, construct a rectangular solid.



B. Determine the length, width, height, and volume of the solid.



C. Draw a diagram of the solid showing its dimensions and volume.



D. Using a different number of cubes, construct another solid and determine its volume.



E. Draw a diagram of the solid made in D. Show its dimensions and volume.
