Order of Operations
A WebQuest for 6th-8th Grade Math Students
Designed by: Wendy Esquivel- [email protected]
Adopted by: Felicia Andorko- [email protected]
Introduction
Can you go to your classes whenever you want or do you have to follow the order of the schedule you
were assigned? Will your locker open if you use the three numbers in any order? Does it matter if you turn
the lock to the left or to the right first? Does 2 + 5 x 3 equal 21 or 17? You will be using this WebQuest to
find out the order of operations that must be followed when evaluating mathematical expressions so that
everyone gets the same answer.
Task
You are going to determine the order of operations that is used to evaluate mathematical expressions.
Once you have done this, you will discover memory devices the United States uses to remember the
order of operations and compare them to those that other countries use. Then create your own
mnemonic and illustrate it using Microsoft Word. There will be several checks for understanding along
the way including a matching challenge and an online quiz. Finally, you will work with a partner to
analyze a problem that was done incorrectly and create a PowerPoint presentation that identifies the
error in the problem and demonstrates the correct way to evaluate the problem with a step-by-step
explanation.
