By Anne Cutsinger, March 5, 2005

2. Microsoft Office in Education
Provides opportunities
Easy to use and teach
Various programs work well together
Students express themselves and communicate their ideas

3. Microsoft Powerpoint Students love working with color and animation
Students are inspired to create visual presentations
Student work can be posted to the web easily

4. Using PowerPoint in Instruction
Introducing a new topic
Direct Instruction
Guided Questions
Examples :
Order of Operations 1
Order of Operations 2

5. Microsoft Front Page (formerly part of the Microsoft Office Suite)
Mexican American Jeopardy
Ms. Cutsinger’s Math Class

6. Order of Operations Using Integers

7. “Operators” & “Terms”…
12 • • -6
Terms
Operators

8. What do we do first???? It Matters!!!! -5 + 7 • 10 = -5 + 7 • 10
2 • 10 20
• 10 65
It Matters!!!!

9. The Order of Operations
All of Algebra is Based on…
The Order of Operations
1. Parenthesis
2. Exponents
3. Multiplication & Division (left to right)
4. Addition & Subtraction (left to right)
5. Simplify any Fraction

10. What do we do first???? 5 + 7 • 10 = 5 + 7 • 10 12 • 10 120 5 + 7 • 10
5 + 70 75
5 + 7 • 10
5 + 70 75

11. The Order of Operations
Memorize
These
1. Parenthesis
2. Exponents
3. Multiplication & Division (left to right)
4. Addition & Subtraction (left to right)
5. Simplify any Fraction

12. Example 1 -2 -2 + 6(-8 + 5) -20 42 - 6 10 -2 + 6(-3) 42 - 6 -2 + 6(-3)
Holy Mackerel
-2 + 6(-3)
42 - 6 -2
-2 + 6(-3)
16 - 6
16 - 6

13. Example 2
12 • • -6
-42

14. Evaluating Algebraic Expressions
(2a) b2
Evaluate when a = -2, b = 4
(2•-2) •42
(-4) (4)2
(16)
16 + (-48)
-32

15. More “Placeholders” x2 - 2y2 + y Evaluate when x=7, y=-3
(-3)2 + -3
(9) + -3 28

16. Variables can “Vary” x2 - 2y2 + y Evaluate when x = -5, y = -2
(-5) (-2)2 + -2
(4) + -2 15

17. 2 only has power over the a (not the negative sign)
Looks Easy BUT…
2 only has power over the a
(not the negative sign)
Evaluate when a = -2
-a2
