Addressed:                 38.   Compare theoretical and experimental probability in real-life situations (D-5-M)

Mini-Lesson Procedure:
Objectives:                Objectives: Experimental and Theoretical Probability
(list all that apply)      1. Identify experimental and theoretical probability.
2. Compare experimental and theoretical probability in real-life situations.
3. Create the sample space to show all of the possible outcomes of an event.
4. Calculate the experimental probability of specific events.
5. Create a PowerPoint slide show to present to the class defining experimental and theoretical
probabilities and providing examples of each.( slide show checklist )

Procedures:

Essential Questions:
1. What is a probability?
2. How is probability determined?
4. How can our understanding of experimental and theoretical probabilities affect our understanding of the world
around us?

Pre-Assessment for Linear Equations Activity
1. Pre-Assessment: The teacher will pre-assess students’ knowledge of probability.
(It would be most useful to pre-assess student knowledge prior to the lesson introduction, this would give teachers
knowledge of how advanced in skills students are or which skills need to be further addressed.)
a. The teacher will complete a standard teacher created pre-assessment (based on availability of

2. PowerPoint as a teacher tool: The teacher will present the iLEAP warm-ups, an introduction/teaching video
from Unitedstreaming, Glencoe links, other lesson samples as needed, reproducible materials and close with a 3-
2-1 summarization.

3. Students will watch the Unitedstreaming video clip- real-world example of probability.

Real-world example A: Scenario- What are the Possibilities?
In the classroom, there are 18 students. Six are boys and twelve are girls. Experimental and theoretical
probabilities are explained and demonstrated using the students in the classroom.

-Teacher will pause the video and have students reflect by creating a journal entry about the video clip.

4. After students share reflections the teacher will provide more examples (these examples can be taken from
Glencoe transparencies already on the PPT or other.)

probabilities.

5. Collaborative Groups- Original Scenario for students’ technology product-Student groups will complete and
present a PowerPoint slide show which includes: an original scenario with graphics to illustrate experimental and
theoretical probabilities and the group’s explanation of their findings. Students will be allowed to use any
necessary means to complete the slide show. Students will present their finding to the class.

Teacher’s Technology Tools                                                   Student’s Technology Tools
