## Reflection: Developing a Conceptual Understanding Quiz + The Language of Probability - Section 3: Class Work + Closing

Probability is a unit that requires as much work with manipulatives as possible. The reason many students often struggle to understand probability and statistics concepts is that they lack a schema for what experiments/trials look like. By having students practice as many real life trials as possible, we can get them close to understanding probability as a percent. This is how I spent the additional time I gained this year in my 90 minute periods.

After reviewing the language of probability with students and emphasizing the use of percentages (100% - certain, 0% - impossible, etc), students were given a coin and a die. We spent 10 minutes performing two experiments (flipping a coin and rolling a die) and recording our results. Students were instructed to flip the coin 20 times in 5 minutes and record their answers. Then they were asked to roll the die 20 times and record those answers. We pooled the totals and calculated the percentages for each event at the end of the experiments. Activities like these can reinforce the use and understanding of the language of probability

I’ve included additional resources found online that extend these types of activities and reinforce the language.
