1. Topic-
|
Know Your Order of Operations |
|
|
2. Content-
|
How do you solve a math problem if there is adding, subtracting,
division, and so fourth, AND if there are no parentheses or brackets?
How do you know which to do first? Add, divide, multiply? Which one?
When there are no other indications as to which computation to do
first, mathematicians follow The Order of Operations rule. Parentheses,
Exponents, Multiply, Divide, Add, Subtract.
NEW TERM - PEMDAS

6. Procedures/Methods-
|
A. Introduction-
You have learned that when you write algebraic expressions, use
+, -, and = signs; and for division, use / , the same way you know
that when you see a fraction, it means to divide the top number by
the bottom number. Then, for multiplication, we learned to write the
expression with no symbol or sign between them (such as 3a), with
an X , or using parentheses.
But what how do you know what operation to do first? |
|
|
B. Development-
1. Explain Order of operations and their importance
2. Teach the four- step procedure.Using the SMART Notebook presentation
3. Explain procedure and rules
4. Model how to work four sample problems.
|
|
|
C. Practice-
1. Students will do 4 practice problems on the board
2. Call students to solve these
3. Re-explain concepts to reinforce PEMDAS
4. Students will do two problems independently and I will provide
answer |
|
|
D. Independent Practice-
1. Order of operations Activity
2. Worksheet number 1
|
|
|
E. Accommodations (Differentiated Instruction)-
1. Students will be allowed 20 minutes to start their homework for
the night. During this time they can ask questions that they need
addressed.
2. I will group students for the activity.
3. Throughout my SMART board presentation my math examples will have
a variety of difficulty.

F. Checking for understanding-
1. Question and answer sessions throughout lesson
2. Feedback from students
3. Assessment and Activity |
|
|
G. Closure-
1. Name the order of operations
2. Review negative + negative
3. Preview next lesson |
