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 warm-up Warm-up sheet worksheets notebook calculator
6. Methods Used and Procedures-

A. Introduction-

 1.Students complete the wram-up 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 10-15 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.Cover-copy 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
