Order of Operations

Today's lesson is "Order of Operations".  Great News!!! I have found some really great ways besides just a textbook to learn about this topic.

Let's begin.  The first website that I will be using is Cool Math.  We are going to break down the "Order of Operations".  The lesson is under the PreAlgebra tab and then click Order of Operations.

Now that we have done several together, I want you to practice the ones below (30 total).  Answer them on your sheet of paper or on a page.doc.  After you have finished either email me your work smiller@bcbe.org or turn in your paper to me (make sure your name, date and which block you are is on it).

6. 2^3−1
7. 9×(6−6)
8. 7+1+8
9. (5+1)1
10. 2×3÷2

12. 7×2÷1

Great Job, I will walk around looking at these.  Now let's turn it up some and raise the bar.  Work the next 15 problems.  You can do this.  If you have any questions, raise your hand.  Once you are done,

**You did it, I will work on grading these and seeing what we need to work more on** Now time to wrap up everything you have learned.  Let's play, Who wants to be a Millionaire"

Okay I want you to divide into teams of 2.  Each team needs a computer.  Each team will play against another team.  We will keep doing this until the last five minutes of class and decide who the surviving teams are.  Good Luck!!!    This is the link to the game, Millionaire's Game you and your partner will be considered one person.  I want you to work in pairs so that you can help each other.
