A Learning Activity is a strategy a teacher chooses to actively
engage students in learning a concept or skill using a digital tool/resource.

Procedure
1. Introduction (5 minutes, whole group) The teacher will discuss the reason Scientific Notation is used:
The teacher will say, "Many mathematicians, statisticians, and other professionals who regularly work with large numbers use scientific notation to break down the numbers into more manageable amounts and for easier calculation. Scientific notification allows individuals to more easily understand the number and simplify arithmetic operations. We will explore the definition of scientific notation, why it's important, how it works, and the different ways you can write in scientific notation."
2. Watching the video (10 minutes, whole group):
The teacher will define scientific notation as a way to express numbers that are too big or little to write in basic decimal form. Scientific notation is also referred to as standard form, scientific form, or standard index form in some settings. Most frequently used by scientists, mathematicians, and engineers, scientific notation allows professionals and others to write very long numbers in a much easier-to-understand manner. When using a scientific calculator, the scientific notation can be implemented by selecting the "SCI" display mode.
Students will observe, take notes, use their math journals or paper, and ask questions.
3. Conclusion(10 minutes, whole group)
The teacher will review the lesson content embedded in the Using Scientific Notation video, using the Operations with Scientific Notation Introduction Practice, and answer any further questions the students may have concerning performing operations with numbers expressed in scientific notation, including problems where both decimal and scientific notation are used.
Assessment Strategies:
The student responses during the class discussion will be used as a formative assessment.
The students will need math journals if used for notes or paper if math journals are not used.
To get the most from the activity, students should be comfortable with writing numbers in Scientific Notation.
Variation Tips (optional):
The teacher can assign the example problems through a digital platform and have the students work on the problems first before the whole group learns together.
The teacher can have the students write their notes on plain notebook paper instead of in math journals.
Notes or Recommendations (optional):
This activity can stand alone or be used as a Before/Engage activity for the following learning activities:
