ORDER OF OPERATIONS - EXTRA PRACTICE

Here are some websites with games and helpful information so you can continue to practice working with the order of operations. We will continue to work on this Monday so make sure you are ready. If you complete any of the activities make sure you comment with a short explanation of what you worked on.

RELAY RACES IN MATH CLASS????
















Sharpen up those pencils and get ready!

LET THE RACING BEGIN!

1) I will split the class into 5 or 6 teams. Our teams will be in rows.
2) I will give each team the same order of operations problem.
3) Each student on the team is allowed to complete only ONE step. To keep track of this each team member will have a different colored pencil.
4) When the student finishes his/her step, he passes the paper back (the last person in the row has to run up and give the paper back to the first student) until the problem is completed.
5) The first team to finish wins … almost. The teams that aren’t done must turn the paper over while I check the answer. If it’s incorrect, I will write the work on the board and the remaining teams can resume their problem solving until a team comes up with the right answer. Afterwards we will find the error together so that all teams can be successful on the next round.

GOOD MORNING FRIDAY!!!!!!!!!!!!!!!!!!!!!!!!!!

Today in class we will be doing more practice on the Order of Operations and then begin our official introduction into Algebra.

MORE ORDER OF OPERATIONS

Today in class we continued to talk about the Order of Operations. The following 6 problems were put on the board to be worked in class.

1.)  (18 ÷ 2) - 4
          9 - 4
             5

2.)  14 ÷ 2 x 14 - 12
          7 x 14 - 12
             98 - 12
                 86

3.)  20 ÷ 10 + 21 x 25
          2 + 21 x 25
              2 + 525
                527

4.)  9 + 23 + (11 - 3) x (4 ÷ 2)
        9 + 23 + 8 x 2
        9 + 23 + 16
         48

5.)  14 ÷ 7 x (6 ÷ 2) x 10
       14 ÷ 7 x 3 x 10
          2 x 3 x 10
               60

6.)  23 + (5 x 3) - 3 ÷ 1
      23 + 15 - 3 ÷ 1
      8 + 15 - 3 ÷ 1
       8 +15 - 3
        23 -3
         20

IS OPERATING IN THE CORRECT ORDER REALLY THAT IMPORTANT?

Does a doctor need to operate in a particular order?
Is there a correct order for getting ready for school?
Is it easier to count when you start with 1?
Is it better to do classwork and practice skills before you take the test?
Is it safer to know how to drive before you go on a road trip?
Is it better to start reading at the beginning of the book?

YES!!!!!

There is a PARTICULAR order we should do things for almost every activity we do in life. In math there is a particular order that we have to work problems. This is called the ORDER OF OPERATIONS, there is an order that we have to work out math problems especially when there are multiple operations used in 1 problem.

Check this out!!! With this problem, 9 + (2 x 4) - 22 ÷ 4, I bet some of you would get 10 and some of you would get 16. Which is correct?

Look at the following stuff to see if it helps you decide










PARENTHESES

EXPONENTS

25 + 6 - 8

31 - 8



ANSWERS: 1.) 24, 2.) 17, 3.) 365

























So what is the answer to 9 + (2 x 4) - 22 ÷ 4? Is it 10 or 16?
