Lesson Plan : Scientific Notation
Teacher Name: | Christin Jacobs |
Grade: | Grade 9-10 |
Subject: | Math |
Topic: | Add, subtract, multiply, divide and compare numbers written in scientific notation. |
Content: | Estimate, compute and solve problems involving scientific notation, square roots and numbers with integer exponents. |
Goals: | Teacher will model how to add, subtract, multiply, divide and compare numbers written in scientific notation. Teacher will relate subject matter to real life examples of when scientific notation is used. |
Objectives: | Students will be able to add, subtract, multiply, divide and compare numbers written in scientific notation. Students will discuss different ways they believe scientific notation will be used. |
Materials: | Projector, calculator, PowerPoint, smartboard (If available), chalk board or whiteboard. |
Introduction: | Introduce the symbols and how to write in scientific notation. Review how to read in scientific notation. |
Development: | Provide steps in setting problems up in scientific notation. Then explain how to add, subtract, multiply,and divide in scientific notation. Finally set answer back to numeric denotion. |
Practice: | Students will be given separate problem numbers at the whiteboard that they will have to work from numeric form into scientific notation then back to numeric form. |
Accommodations: | Students will be given extra time if needed to complete worksheet. |
Checking For Understanding: | Worksheets will be graded before students leave to use as guides for completing homework. Extra problems will be given at this time to students who struggled on worksheet. |
Closure: | End lesson with a few relationships to real life use of scientific notation. |
Evaluation: | In class worksheets will be graded for completion and graded for level of understanding. Homework is collected and graded based on complete steps and correct computations. |
Teacher Reflections: | I would have liked to add more real world math. I was thinking of giving them a scenario based problem where they have a set amount of time to complete a task. |
