Students use the calculator to compute the value of expressions involving order of operations.
Before the Activity
See the attached PDF file for detailed instructions for this activity
Print the Transparency sheet and pages 25 - 27 from the attached Student PDF file for the class
During the Activity
Distribute the pages to the class.Understand that mathematicians have developed an agreed-upon order of operations
First complete exponentiation, second complete multiplication and division, third complete addition and subtraction, from left to right
Use the calculator to determine the value of different expressions
Find alternate ways to complete each computation (break the expression into parts)
Record the keystroke sequence used for each solution
Follow the activity procedures:
After the Activity
Students complete the Student Activity pages.
Review student results
As a class, discuss questions that appeared to be more challenging
Re-teach concepts as necessary
