Lesson objective: Estimate quantities in real-world scenarios using experimental probabilities written as percents.

This lesson helps to build procedural skill with calculating experimental probabilities as percents. Percents are used here because they allow quantities to be calculated even when the numbers involved are not compatible. This work develops students' understanding that experimental probabilities can be used to make estimated predictions.

Students engage in Mathematical Practice 4 (Model with mathematics) as they model real-world scenarios as experimental probabilities written as percents, and use them to estimate quantities.

Key vocabulary:

  • experimental probability
