Lesson 4
Tables of Relative Frequencies
Lesson Narrative
The mathematical purpose of this lesson is to make connections between two-way tables and relative frequency tables and to use the tables to determine probabilities for some events. The work of this lesson connects to previous work because students used sample spaces to calculate probabilities of compound events. The work of this lesson connects to upcoming work because students will use tables and Venn diagrams to determine probabilities for some events. When students use two-way tables to estimate probabilities they are seeing and making use of structure (MP7).
Learning Goals
Teacher Facing
- Interpret (orally and in writing) a two-way table that represents a sample space.
- Use information in a two-way table to calculate relative frequencies and to estimate probabilities.
Student Facing
- Let’s use tables to organize probabilities.
Required Materials
Required Preparation
One standard number cube is needed for each student.
Learning Targets
Student Facing
- I can use information in a two-way table to find relative frequencies and to estimate probability.
