1. Topic Of Lesson Plan

Scientific Notation
Problem Solving 


2. Lesson Content

Use problem solving techniques to find answers to questions involving
scientific notation. 


3. Goals And Expectations

1.Standard 8.1.1 Read, write, compare and solve problems using decimals
in scientific notation 


4. Objectives

1.Students will work in cooperative groups to analyze word problems
and develop problem solving steps to find the answer
2. Students will check their answers to see if they are reasonable 


5. Materials and Aids

Whiteboard
Overhead
Transparency warmup
Warmup sheet
worksheets
notebook
calculator 


6. Methods Used and Procedures

A. Introduction
1.Students complete the wramup transparency over problems of scientific
notation
2.go over answers and correct misconceptions
3.collect papers 


B. Development
1.Explain that scientist use the information to try and understand
how it relates to other things. For example, we have the International
Space Station (ISS) in orbit around the earth. It has taken many calculations
of physics to determine the successful operation; how far from the
earth will it orbit; how long can it stay in orbit; when we need to
send people or supplies, what speed and time within seconds do we
launch?
These are all problems that had to be worked out to make the ISS successful
before it was launched with people on it. Any problem that mathematicians
need to solve can be approached using the following four steps.
Understand, Plan, Solve, Check.
Hand out the guidelines and worksheet.
Have student volunteers read the 4 steps.
Work through the first example together.



C. Practice
1.Explain the process to the students. Each tribe is to complete
the 4 exercise examples together
2.Give the tribes 1015 minutes to complete them together
3.Give the correct answers (or have them displayed for students to
check) 


D. Independent Practice
1. Hand out the problems with scienctific notations
2. Assign each tribe 1 of the questions
3. Their assignment is to design the steps to solving the problem.
Remind them that these have mutliple steps. Each step must be listed
in detail and worked out mathematically. Answers will be shared with
the class.



E. Accommodations For Students
1.Covercopy sheets
2.Reduced # of problems



F. Checking for understanding
1.During instructions, ask for questions
2.Walk around the room and look at students' practice sheets



G. Closure
1. Sharing the answers and steps with the class. 


7. Evaluation

1. Practice sheets
2. homework
3. quiz
