I.        Introduction             

a.       The teacher will begin with putting a Warm up on the screen called “Sponge”.

                                                   i.      Review:

1.       83 less than a number n

2.       2 less than the product of 7 and a number m

3.        Half of x

                                                 ii.      What are the Order of Operations? What do you know about them?

II.      Body 15-20mins

a.        Students will enter notes from the session in their math composition books.

                                                   i.      Slide two: Evaluate  7 + 4 • 3.

1.       Is your answer 33 or 19?

2.       You can get 2 different answers depending on which operation you did first.  We want everyone to get the same answer so we must follow the order of operations.

                                                 ii.      Slide three: Remember the phrase
“Please Excuse My Dear Aunt Sally” or PEMDAS.

1.       ORDER OF OPERATIONS

2.       1.  Parentheses - ( )  or [ ]

3.       2.  Exponents or Powers

4.       3.  Multiply and Divide (from left to right)

5.       4.  Add and Subtract (from left to right)

                                               iii.      Slide four through seven include examples

1.       7 + 4 · 3

2.       3(3 + 7) ² ÷ 5

3.       20 - 3 • 6 + 10² + (6 + 1) • 4

b.       During the session, students will have the opportunity to interact with the presentation through solving problems online.

                                                   i.      Slides eight through ten

1.       11² + 18 - 3³ · 5 Answer: 4

2.       16 - 2(10 - 3) Answer:2

3.       24 – 6 · 4 ÷ 2 Answer: 12

c.        Students will continue to  enter notes from the session in their math composition books.

                                                   i.      Slide 11:

1.       Evaluating a Variable Expression To evaluate a variable expression    

a.        Substitute the given numbers for each variable.

b.       Use order of operations to solve.

                                                 ii.      Slide 12 through 13 include examples

1.       n + (13 - n) ¸ 5       for  n = 8

2.       8y - 3x² + 2n     for x = 5, y = 2, n =3

d.       During the session, students will have the opportunity to interact with the presentation through solving problems online.

                                                   i.      Slides 14-16

1.       10 – 4x  if  x = -13? Answer 42

2.       5k³ if k = -4? Answer -320

3.        if n = -8, m = 4, and t = 2 ? Answer -6

e.        Provide continuous feedback – are they getting it?

                                                   i.      The teacher will give practice problems throughout the lesson.

                                                 ii.      If students are having trouble with problems, teacher will go over material again and reteach.
