## Reflection: Relevance Theoretical vs Experimental Probabilities - Section 1: Do Now + HW Check

The balance of rigor and approachability of the Do Now is a daily battle I have to fight. The Do Now must involve a task ALL students are able to complete independently, and yet challenge them in terms of rigor as well, pushing them to think about the concepts deeply to prepare for the day’s lesson. The Do Now attached to the original lesson lacks both relevance and rigor. I re-wrote the salamander problem (#1) to make it more rigorous. Then, I placed both of these problems in the homework sheet in order to review the concept.

Since we are beginning the probability section of this unit, I decided to instead create a Do Now that checked the understanding of the “language of probability” from the previous lesson. This makes the Do Now more relevant as it connect directly to the lesson. By including questions with the same language used the day before I hope to make the problems approachable, but I never know until my students actually complete the Do Now. Those precious 5 minutes while students are working silently and I am walking around are where I find my potholes – misconceptions I may have missed in the previous lesson’s exit ticket or lesson. Strategic grouping of students to review their answers can often be the best way to address this issue.

# Theoretical vs Experimental Probabilities

Unit 7: Statistics and Probability
Lesson 10 of 11

## Big Idea: students complete classwork in pairs and reflect on the difference between theoretical and experimental probabilities, including why they do not always equal each other when an experiment is carried out
