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
 
3. Goals: Aims/Outcomes-
1. Apply order of operations
2. Learn PEMDAS
3. 90% of students will understand and comprehend given material
4. The learner will model and solve problems using algebraic methods
 
4. Objectives-
By the end of this lesson the student will be able to:
1. Apply the order of operations to solve math equations.
2. Understand the order of operation rules.
3.The students will solve eight out of ten order of operations problems correctly
4. Compare and order integers.

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
 
7. Evaluation-
1. Grade and evaluate
2. Compare to pretest
