- 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 students 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.
