Keeping Order

Introduction

Why is order important?

If we do not have order, what will happen?

We are going to learn how to put things in order to solve expressions.

Description: This WebQuest introduces order of operation. Students will learn how to simply expressions using the order of operations property. Students will also use properties and operations to determine if two expressions simplifies into each other.

Grade Level: 9-12

Content Standard: 1.1 Students use properties of numbers to demonstrate whether assertions are true or false.

                              25.1 Students use properties of numbers to construct simple, valid arguements (direct and indirect)    

                                    for, or formulate counterexamples to, claimed assertions.

Curriculum: Math

Keywords: oder of operation, terms, like terms, coefficient

Task

This webquest will teach you:

1. The defintion of order of operation

2. How to simply expressions



Process

You already learned about the properties of addition and multiplication. If you are still unsure you can go to http://www.purplemath.com/modules/numbprop.htm 

Today, we are going to use the properties with a new set of properties in order to simply expressions through Order of Operation.

Order of Operation Properties:

1st: Perform operations inside grouping symbols

2nd: Evaluate powers

3rd: Perform multiplication and division from left to right

4th: Perform addition and subtraction from left to right

What is it important to have order in mathematics?

Order of Operation Practice

 

Directions: calculate the following problems using order of operation.

 

1.  15 – 2 x 5 + 3                                             2. (3 x 4) 2

 

 

3. 7 + 3 x 29 – 4 2                                       4. 5[4 + (8 – 2)] 

 

5. 10÷2 + 7 x 32                                            6. 2(3+ 6÷2)2

Conclusion

You began this WebQuest wondering why is it important to have order. Without order there can be choas or incorrect answers. With practice you were able to deomstrate your level of understanding of order of operation.
